  • On-farm conservation of cassava, cuiabá, Mato Grosso: ethnobotanical aspects and genetic diversity
  • Data: 28/01/2022


  • Mostrar Abstract
  • This research aims to analyze the on-farm conservation of cassava practiced by a community in the Baixada Cuiabana region, state of Mato Grosso, under the ethnobotanical and molecular aspects, through the study of the genetic diversity of the collection they maintain. Root and tuber cultures originating in tropical regions play an important role in Brazilian small-scale agriculture, especially cassava. In the Baixada Cuiabana region, there is a strong characteristic that traditional farmers have in common, which is their dedication to the production of cassava, with in-depth knowledge about the management of ethnovariety, production and processing. Farmers were interviewed about ethnobotanical aspects of cassava, applying a questionnaire with open questions regarding the characteristics of each ethnovariety maintained by the farmer, morphological and physiological aspects, and how the vine was acquired. The collected sheets for molecular characterizations with fluorescent microsatellites. The leaf tissues of the cassava species they maintained were inserted into 2.0 mL polypropylene tubes with loading buffer (containing 1 mL of saturated NaCL-CTAB solution, 70g of NaCL, 3g of CTAB dissolved in 200 mL of water distilled). Then, the material was identified and sent to the Phytochemical Laboratory of Embrapa Agrossilvipastoril, Sinop-MT, and stored in a freezer at -4ºC until DNA extraction. To analyze the genetic diversity of cassava ethnovarities, allele frequencies, number of alleles per locus (A), expected (He) and observed (Ho) heterozygosity, allele fixation index (f) and percentage of polymorphic loci were estimated. (%P) through the GDA program - Genetic Data Analysis. The mean for expected (He) and observed (Ho) heterozygosity stands out with significant values, 0.67 and 0.72, respectively, with observed heterozygosity was higher than expected in nine of the 15 loci analyzed. Farmers' ethnobotanical practices contributed to the high genetic diversity found in the collection. There are rare alleles within the evaluated population, which reinforces the importance of maintaining and expanding the on farm/in situ conservation of these collections in order to stop genetic erosion. The matrinxã ethnovarity stood out for being the most divergent among the collection.

  • Data: 21/02/2022


  • Mostrar Abstract
  • The glass of milk is a cut flower belonging to the Araceae family, originating from flooded regions of Africa, 
    with great economic potential, being produced mainly in cold climate regions, which provide a greater number 
    of quality flowers. Despite being a plant of great economic importance, it does not stand out in local production in 
    the state of Mato Grosso, given the adverse environmental conditions. Cultivation in hot climates is not impossible, 
    although it may become unfeasible, given the amount spent to acclimatize greenhouses and/or environments. 
    Another point that also makes the process more expensive is the automation system, in the case of hydroponic 
    systems, which also requires prior knowledge from the producer in its handling. Therefore, the present work will 
    aim at the production of commercial standard flowers, from milk cups, using for this the cultivation in a vertical 
    hydroponic system, with refrigeration of the nutrient solution, this entire system being controlled by the low-cost 
    automation platform Arduíno, in the experimental area of the State University of Mato Grosso “Carlos Alberto 
    Reyes Maldonado” (UNEMAT), Campus de Cáceres-MT.

  • Mostrar Abstract
  • Beans are among the main crops of greatest economic importance and the most produced in the Brazil. 
    One of the main problems that affect the culture are diseases, between the main one and the one that the 
    most significant loss is Fusarium wilt, caused by the Fusarium pathogen oxysporum f. sp. phaseoli, and its
    main control measure is the use of resistant cultivars. THE identification of sources of resistance and development 
    of resistant cultivars is one of the targets of plant genetic improvement. Thus, the objective of this work is to 
    identify SNPs markers associated with Fop resistance in common bean.

  • Mostrar Abstract
  • Due to the great demand for bioenergetic species on a world scale, the safflower crop has been highlighted as an important alternative for energy production. Safflower is an oilseed with several applications, in addition to its bioenergetic potential, it has high value for human consumption, in the food, industrial, ornamental, medicinal and animal consumption sectors. In addition, it has aroused interest in national agriculture, as it presents itself as an option for second crop cultivation, not competing for area with crops used for human consumption. However, the lack of technical knowledge regarding its cultivation and the lack of improved cultivars adapted to our environment is one of the reasons that prevent the expansion of this culture in the country. Considering that safflower genetic improvement is essential to increase its acceptability and utility as a global oilseed, the objective was to estimate the genetic divergence between safflower accessions in terms of morphological, agronomic, chemical and molecular characters using the Gower algorithm. A total of 116 genotypes from the LRG&B - UNEMAT Germplasm Collection were evaluated. The information regarding the morphoagronomic, chemical and molecular characterization was obtained through field and laboratory experiments carried out at the State University of Mato Grosso (UNEMAT), Mato-Grossense Company for Research, Assistance and Rural Extension (EMPAER) and Instituto Federal of Mato Grosso (IFMT). For data analysis, a joint analysis of the data was performed, in which the Gower Algorithm was used to create the dissimilarity matrix. The resulting matrix was submitted to different clusters, such as the Tocher Optimization, Hierarchical UPGMA and Ward-MLM clustering methods. The clustering methods applied were efficient in distinguishing the accessions and the results indicate the existence of genetic divergence between the safflower genotypes. Pi 193473, pi 195895, pi 237539, pi 262443, pi 279344, pi 401474, pi 401475, pi 401475, pi 406006, pi 537658, pi 544028, pi 532639, pi 568787, pi 568787, pi 613382, pi 613382, pi 613503, pi 638543 were the most divergent genetically, being indicated for possible crosses.

  • Data: 28/02/2022


  • Mostrar Abstract
  • The genus Catasetum is formed by the species that belong to the Cymbidieae group, many of these species are terrestrial, the genus is the one that most arouses interest in botanists, due to its admirable adaptation and the trimorphism in its flowers. Studies related to the chromosome number for this genus point to a large chromosomal variation, directing hybridization as one of the responsible for the increase in diversity, a fact that can be commonly used to seek characteristics considered to be of greater acceptance. Therefore, this work aims to perform the chromosomal characterization of Catasetum saccatum x Catasetum saccatum mutant, from the analysis of chromosomal morphometry to contribute to botanical, evolutionary and genetic improvement studies. The cariological variability of these plants generates results that may present possible differences between the species based on the chromosomes. The study was carried out at the Laboratory of Cytogenetics and Plant Tissue Culture of the University of the State of Mato Grosso “Carlos Alberto Reyes Maldonado” (UNEMAT) Campus of Alta Floresta - MT, using explants of Catasetum saccatum x Catasetum saccatum mutante cultivated in the Alta Floresta Orquidário. Florestense of the same unit. For cell blockage, root meristems were blocked in 3 μM amiprophos-methyl (APM) for 15 hours, then the roots were fixed in methanol:acetic acid (3:1) solution. To prepare the slides, the treated meristems were washed to remove excess blocker, after which the roots were exposed to enzymatic digestion composed of three enzymes in a water bath at 36°C, for 1:30 hours, for later staining of the slides. slides were stained with 5% Giemsa solution (Merck KGaA). Observations were performed using a Microscope, and measured using the MicroMeasure program version 3.3 (MM). In view of the chromosomal morphometric analysis, we observed that the C. saccatum species has a total of 54 chromosomes, and the mutant C. saccatum species, in addition to the characteristics visibly observed in the flowers, has a chromosomal deletion in pair 2, with the loss of the satellite in one of the chromosomes, causing the appearance of 3 male structures in the plant. Thus, classical cytogenetics is extremely necessary in the analysis of mutations occurring in species.

  • In vitro production of synthetic hexaploid and evaluation of seed behavior of triploid plants of Passiflora cincinnata Masters

  • Orientador : MAURECILNE LEMES DA SILVA
  • Data: 28/02/2022


  • Mostrar Abstract
  • The production of polyploids is a relevant strategy in genetic improvement programs for the selection and cultivation
    of ornamental and commercial plants. This is because polyploid individuals generally have greater vigor compared to
    their respective diploids, exhibiting significantly larger vegetative and floral organs. Due to the triploid nature of the
    endosperm, an embryonic reserve tissue, its in vitro culture is considered a relatively simple biotechnology method
    for obtaining triploid plants, being an important tool for use in plant genetic improvement. In the genus Passiflora, 
    endospermic tissue culture is little explored and with many gaps in knowledge. Thus, the project aims to increase 
    the ploidy level in triploid (3n) plants regenerated in vitro from the endosperm tissue by the embryogenic pathway 
    of genetically stable plants with the use of antimitotic agents, aiming at improving the morphoagronomic characters 
    in Passiflora cincinnata. Plants obtained from polyploidy will be evaluated by cytogenetic analysis and evaluation of 
    vegetative and reproductive attributes of the obtained plants, with the future perspective of producing new cultivars.

  • GENETIC PARAMETERS OF COMMON BEAN RESISTANCE TO THE PHYTOPATHOGEN CAUSING WHITE MOLD

  • Orientador : THIAGO ALEXANDRE SANTANA GILIO
  • Data: 28/02/2022


  • Mostrar Abstract
  • Common bean (Phaseolus vulgaris L.) is a legume with great importance in human food for all social classes, especially for the poorest, due to its low cost and great nutritional qualities and great economic and social importance, being its cultivation affected by several biotic and abiotic factors that reduce productivity and make the product more expensive for the final consumer. Among the main pathogens, Sclerotinia sclerotiorum Lib. de (Bary), the phytopathogen that causes white mold, stands out for its wide dissemination, potential damage to crops and resistance structures. This work aimed to determine the genetic factors that make up the physiological resistance of common bean to the phytopathogen that causes white mold. Crosses between common bean genotypes BGF 13 X BGF 89, BGF 20 X PI 207262 and BGF 20 X BRS FC 402, contrasting in terms of resistance to white mold previously selected and from different gene pools, were obtained, obtaining the generation F1 and F2 segregating generation. The resulting plants in F2 were inoculated with an isolate of the phytopathogen that causes white mold by the “seedling straw test” method (seedling straw test) and the variables noted at day 5, Area Below the Disease Progress Curve (AACPD) and Plant Disease Ratio (RDP) were used to determine environmental variance, genotypic variance, phenotypic variance, broad-sense heritability and number of genes through the joint scale test performed in the genes statistical software. The environmental variance represented, in general, a large part of the phenotypic variance, indicating that the characteristic white mold resistance is moderate to highly influenced by the environment, in agreement with what has already been reported in previous studies. The genotypic variance was expressive only for the variable RDP in the crosses between BGF 13 X BGF 89 and BGF 20 X PI 207262, moderately expressive for the variable Grade at 5th day and AACPD for the BGF 20 X PI 207262. The segregating generation F2 presented individuals with resistance and susceptible, indicating the efficiency of determination of resistant individuals by the straw method in seedlings and the polygenic nature of resistance to white mold. Broad sense heritability was moderate to high for white mold resistance. The estimate indicated the number equal to or greater than 2 genes in the expression of resistance to white mold, indicating the action of polygenes in the determination of resistance to white mold.

  • Mostrar Abstract
  • The Gladiolus (Gladiolus grandiflorus Andrews) is a widely known cut flower, which due to its temperature requirement can be cultivated in different regions of the country. However, studies regarding the planting and management of the crop in the growing region are necessary. The study of spacing is important to determine the best number of plants per row, crop development and productivity. Shade cultivation can be an alternative in regions with higher temperatures such as those found in Mato Grosso. For the Midwest region there are no studies that characterize the reproductive phenophases of the gladiolus, or the determination of the ideal spacing, they are still scarce. This study aims to carry out the morphoagronomic characterization of four gladiolus cultivars grown in single and double row planting systems and in two growing environments: shade and full sun, in the town of Tangará da Serra - Mato Grosso. The experiment was carried out under shade and full sun environments, in a randomized block design, in a 2x4 factorial scheme, with two planting systems (single rows and double rows) and four cultivars (White Goddess, Tradehorn, Peter Pears and Gold Field), with four replications and 14 plants per plot. In each plot, the evaluation of the ten central plants was carried out. The work was divided into two parts, initially the morphoagronomic characterization was executed and the characteristics evaluated were: plant height and plant diameter in each phenophase (R0, R1, R2), flower stem length, inflorescence diameter, inflorescence size, number of flower buds, fresh mass of the inflorescence, day of harvest up to half of flowers of open stem and harvest day up to half of flowers of senescent stem. Afterwards, the classification of the gladiolus stem was carried out according to the commercialization standards of Veiling Holambra, in relation to stem sizes and diameter and post-harvest longevity, the stems were visually evaluated every three days. The results were analyzed individually, submitted to analysis of variance and in accordance with the significance of the F test, the averages were compared using the Tukey test, at 5% probability. The shade environment presented greater precocity between the phenophases and in the total flourishing cycle, ranging from 67 to 70 days, while the variation in full sun was from 76 to 85 days. The system of double rows in shade environment was higher in productivity between 20.43% and 25.92% than in single rows, with emphasis on production for cultivars Peter Pears and Gold Field. In the full sun environment it was observed non-marketable stems, a higher percentage of tortuosities, stains, burns and a 21.17% lower productivity. The longevity between cultivars ranged from approximately 4 to 5 days. For the state of Mato Grosso, the most recommended environment for the production of gladiolus is the shading in double row systems, as they provide better quality stems and greater commercial value.

  • INTERACTION BETWEEN BIOMASS SORGHUM GENOTYPES AND GROWING ENVIRONMENTS IN MATO GROSSO STATE
  • Data: 09/03/2022


  • Mostrar Abstract
  • Acting in the generation of thermal energy, as a substitute for combustion in boilers, or production of low-cost roughage for animal feed, sorghum biomass has gained space in recent years, due to its formidable characteristics both for co-generation of energy and the possibility of be ensiled and fed to animals. In view of this, research aimed at increasing the productive potential is prioritized, however studies of the genotype x environment interaction (GxE) are important, since this is one of the greatest difficulties when recommending cultivars for planting in different locations. Thus, the objective was to evaluate the interaction between biomass sorghum genotypes and cultivation environments in the State of Mato Grosso for the characteristics height, green mass production (PMV), dry mass production (DMS) and biomass moisture at harvest. Thus, in a 24 x 2 factorial scheme (24 genotypes x 2 environments), 22 biomass sorghum genotypes and two silage sorghum cultivars, used as controls, were cultivated in the municipalities of Cáceres and Sinop, in a randomized block design, with three repetitions. The useful experimental plots consisted of 2 rows of five meters, spaced 0.70m apart. The data of the measured characteristics were submitted to analysis of variance and the means of the genotypes, for the characteristics that demonstrated significance in the F Test (P<0.05) were grouped by the Scoot-Knott test, at 5% probability. The presence of the GxE interaction was verified for all the characteristics mentioned above. When splitting the GXA interaction into its simple and complex parts, as proposed by Cruz and Castoldi, with the exception of height, the other characteristics showed that the complex part prevails. Such results indicate that the best genotype for cultivation in Cáceres does not coincide with the best for Sinop. New tests are recommended in a greater number of environments in Mato Grosso that allow a study of the adaptability and stability of genotypes, thus allowing the safe recommendation of biomass sorghum genotypes for cultivation in the state.

  • Mostrar Abstract
  • Cassava (Manihot esculenta Crantz) is cultivated in several brazilian regions, it is one of the crops of greatest socioeconomic importance for the country. It has a wide possibility of use, such as in the manufacture of food products for human and animal consumption. This study aimed to carry out the molecular, phenotypic and culinary characterization of roots of 15 of cassava landraces cultivated in the north of Mato Grosso state, Brazil. For the molecular characterization, young leaves were used for DNA extraction and 15 molecular markers of the ISSR type. The phenotypic characterization of the roots was performed by evaluating the texture of the epidermis, skin color, cortex color and pulp color. Culinary quality was determined by analyzing the facility of peeling the roots, the cooking time, the pre and post cooking weight variation and the cooked mass pattern of roots in natura and stored in the freezer in packages with and without vacuum for 30, 60 and 90 days. Using the ISSR markers, it was possible to confirm the existing genetic diversity among the 15 evaluated cassava landraces. This diversity was revealed by the percentage of polymorphism (72.94%) and by the formation of groups with 15 landraces in the UPGMA, Tocher and Structure cluster analyses. The landraces did not form groups by sample location, which may be associated with the exchange of cassava stems among farmers in the municipalities of MT, an important activity for the maintenance of cassava genetic resources. 73.3% of the evaluated landraces have rough root epidermis texture, 53.3% have dark brown skin color and 73.3% have white or cream cortex color and 60% have white in natura pulp color. The cooking time in a conventional pan ranged from 17 to 35 minutes and the pattern of cooked pasta varied between 5 and 10, while in the pressure cooker all landraces were cooked after 10 minutes, with a pattern of cooked pasta ranging from 4 to 9 minutes. Regarding the evaluation of frozen roots, a better pattern of cooked pasta was observed in roots stored in vacuum packaging. Considering the cooking time and the pattern of cooked pasta, four landraces stood out as promising for fresh consumption (Cascatinha, Folha Roxa, Branca and Amarelinha), and after freezing the landraces: Capelari, Amarelinha, Folha Roxa and Cascatinha stand out.

  • Mostrar Abstract
  • Manihot esculenta Crantz popularly known as cassava, is the only species of the genus Manihot domesticated for human consumption and cultivated for commercialization. Cassava is cultivated in different kinds of soil and climatic conditions, has productive potential and is of significant importance in the diet. The objective of this study was to carry out the morphoagronomic characterization and evaluate the culinary quality of three landraces of cassava in three harvest seasons, in the edaphoclimatic conditions of the municipality of Paranaíta, Mato Grosso, Brazil. The morphoagronomic and culinary characterization were carried out with three cassava landraces (“mandioca de fritar sem cozinhar”, “mandioca branca” and “branquinha”) at three different harvest times (6, 8 and 10 months post-planting). The following characteristics were evaluated: shoot and tuberous root productivity, harvest index, number of roots per plant, length and diameter of the root, skin color, cortex and pulp, root shape, epidermis texture, root constrictions, skin and cortex detachment, cooking time, cooked mass pattern and post-harvest root deterioration. The results show that the harvest times influence the yield characteristics, the landrace “mandioca de fritar sem cozinhar” at six months post-planting, standing out from the others in terms of shoot production as well as tuberous root productivity. As for the phenotypic characteristics evaluated in the roots of the landraces, there was variation, with the exception of pulp color and root constrictions. The “mandioca de fritar sem cozinhar” and “branquinha” cooked in a conventional pot were not influenced by the harvest times, as they presented regular cooking (21-30 minutes) in all evaluations. While the “mandioca branca” was affected, presenting regular cooking only in the eight-month harvest. In the other hand, the cooking time in a pressure cooker was not altered by the harvest seasons in any of the three cassava landraces. Cassava root peeling and cooked pasta pattern were not affected by harvest times. The roots of the landraces presented 20% of deterioration in the harvest at eight months post-planting and in the other harvest times they did not deteriorate, after being kept for five days post-harvest at ambient temperature. We concluded, therefore, that the best time to harvest the three landraces is in the sixth month after planting, being the “mandioca de fritar sem cozinhar” indicated for productive purposes, while for culinary purposes, the three landraces (“mandioca de fritar sem cozinhar”, “mandioca branca” and “branquinha”) are suitable for cultivation on the soil and climate conditions of the municipality of Paranaíta, Mato Grosso, Brazil.

  • This study aimed to verify the presence of genotype x environment interaction in sweet sorghum genotypes in different regions, as well as to identify the most productive materials. For this, the assays were conducted in randomized blocks with three replications, and 21 experimental hybrids and 4 varieties, of these, 2 commercial, of the Embrapa Maize and Sorghum Breeding Program were evaluated. The experiments took place in three locations (Sete Lagoas-MG, Sinop-MT and Jaguariúna-SP), in the periods of first harvest 2018/2019 and second harvest 2019. The following characteristics were evaluated: flowering (FLOR), green mass production (PMV), total soluble solids (SST) and ton of brix per hectare (TBH). Individual variance analyses were performed by environment and together, and then the genotype means were grouped by the Scott-Knott test (P<0.05). Additionally, studies of adaptability and stability and comparison of the Annicchiarico (1992) and GGE biplot (YAN et al., 2000) models were conducted. Occurrences of genotype x environment interaction were observed for all studied characteristics. Among the results, the hybrids 5, 6, 20 and 21 were the earliest and the 14, 17 and 18 were the most productive. In the study of adaptability and stability, the GGE biplot model was more efficient, presenting hybrids 18 and 16 as the most adapted genotypes.

  • Mostrar Abstract
  • The safflower culture (Carthamus tinctorius L.) is one of the oldest in the world, being considered an oleaginous belonging to the Asteraceae family, whose raw material is destined for various purposes such as the production of lubricants, biofuels, soaps, varnishes, cooking oil and animal feed. The safflower culture is a very relevant oleaginous, it has attracted the attention of researchers and industries for having high quality and quantity of oil, being important the accomplishment of studies, mainly in the genetic improvement, that helps in the selection of superior genotypes. In this context, the evaluation of genetic variability with the use of markers is essential for the exploitation of genetic resources in plant breeding programs. Therefore, this work aimed to estimate the genetic variability of 121 safflower genotypes via 21 SSR molecular markers from the Genetic Resources & Biotechnology Laboratory (LRG&B) of the State University of Mato Grosso "Carlos Alberto Reyes Maldonado" (UNEMAT), Campus of Cáceres-MT. The study was conducted in the laboratory and in the vegetation house of LRG&B with controlled humidity and temperature. 121 safflower genotypes were evaluated, 11 of which were not used because they were from populations containing only one genotype, thus avoiding the overestimation of this information for these individuals, so the analyses were made with 110 genotypes from ten different populations. The genetic diversity of the 121 safflower genotypes was estimated by means of number of alleles, mean heterozygosity observed (Ho), mean heterozygosity expected (He) and inbreeding coefficient (F). The number of alleles detected among the genotypes considering the 21 loci was 158, ranging from six (CT6, CT12, CT13 and CT19) to 11 (CT26), with a mean of 8 alleles per locus.  The He can be considered high, ranging from 0.551 to 0.80, with an average of 0.71, while the Ho was low, ranging from 0.00 to 0.50, with an average of 0.03. F results were positive in all locus and in all populations, with a general average of 0.95. The high and positive F values are due to He levels in relation to Ho, both for each locus and in each population, indicating a probable inbreeding process.

  • Mostrar Abstract
  • Common beans (Phaseolus vulgaris L.) are grown worldwide and one of the phytosanitary problems that compromise grain quality and productivity is the pathogen Sclerotinia sclerotiorum (Lib.) de Bary, a fungus that causes white mold. The objective of the study was to select common bean genotypes with a physiological resistance reaction to the pathogen that causes white mold and to identify candidate genomic regions associated with this characteristic. For the selection of parents, the reaction to the disease was evaluated in a panel composed of 114 genotypes using the straw test and seedling straw test inoculation method. The genotypes were genotyped via GBS and obtained, after MAF of 0.05, 28,823 high quality SNPs, using them for associative mapping through the MLMM, FarmCPU and BLINK models. Given the complex nature of physiological resistance, genotypes BL10, BL15, BL18 and BL95 were selected, indicated by both methods used, suggesting a high level of physiological resistance. The regions associated with the physiological resistance characteristic were indicated on chromosomes Pv02, Pv03, Pv09 and Pv10, indicating the presence of the QTL already reported WM2.2 BV, R31 and WM3.1AN, XC, AP in addition to the annotation of genes related to resistance to biotic stresses Phvul.002G023400, Phvul.009G230200 and Phvul_009G232100, in the associated regions, providing candidate genes for validation studies.

  • Mostrar Abstract
  • The genus Catasetum belongs to the Orchidaceae family, which has approximately 300 species distributed throughout the Brazilian territory, which have been gradually destroyed by human anthropic action. The knowledge of the plant genome is of great importance for the characterization of the germplasm, and is essential for genetic improvement works, when crosses are programmed. And, being an integral part of cytogenetics, it has its fundamental contribution in evolutionary and taxonomic studies. In view of the above, the present study aimed to quantify the DNA by flow cytometry of the species mentioned above to generate results that can provide support to characterize the genus and that assist in research related to genetic improvement. The species C. atratum Lindl., C. albovirens Barb.Rodr., C. joaquinianum Campacci & G.F.Carr., C. hopkinsonianum G.F.Carr & V.P.Castro., C. discolor Lindl., C. rooseveltianum Hoehne. For cytometric analysis, young leaves of plants grown in the Altaflorestense nursery were used. Based on the data obtained through flow cytometry we can infer that the DNA content diverged for all species of Catasetuns studied, however Catasetum discolor was the one with the highest value of 9.711pg and Catasetum rooseveltinianum was the one with the lowest value of 6.063pg.

  • AGRONOMIC PERFORMANCE AND PRODUCTIVITY STABILITY OF BIOMASS SORGHUM GENOTYPES CULTIVATED IN THE STATE OF MATO GROSSO

  • Data: 02/02/2021


  • Mostrar Abstract
  • Biomass sorghum has emerged as a crop with high biomass production that can be used for both energy generation and animal feed. However, for the success of a crop, one of the main factors is the use of productive and stable genotypes in the growing region. The present research aiming to provide farmers in the State of Mato Groso with a new alternative for local agribusiness, evaluated the agronomic performance and productive stability of sorghum biomass genotypes through field experiments developed in three different locations in the state. The main objective of the research was to identify cultivars adapted to cultivation in the State of Mato Grosso, which could be recommended for use by farmers. For this purpose, 25 sorghum genotypes were evaluated in the 2019/20 harvest in the municipalities of Cáceres, Nova Xavantina and Sinop. Of the 25 genotypes, four are commercial hybrids, two of which are silageiro (BRS 658 and Volumax) and two are biomass (BRS 716 and AGRI002-E) and the other 21 genotypes are of the biomass type, but experimental genotypes, developed by Embrapa Corn and Sorghum. Average plant height (ALT), green mass production (PMV), dry mass production (PMS) and flowering (FLOWER) were evaluated and the data were subjected to joint analysis of variances of the environments and, subsequently, depending on the means for the different characteristics, the genotypes were grouped by the method proposed by Scott-Knott (P <0.05). For PMV, PMS and ALT, characteristics that demonstrated significance of the genotype x environment (GxA) interaction, the genotype stabilities were evaluated by the method of Wricke (1965). As for flowering, forage hybrids were earlier than biomasses, with BRS 658 blooming, on average at 68 days, and Volumax blooming at 76 days in Cáceres and 72 days in Sinop. The biomasses varied between 115 to 134 days to flower in Sinop and between 127 and 158 days in Cáceres. BRS 658 and Volumax equalized in terms of heights, PMV and PMS, with averages of 2.8 m and 36 t.ha-1 and 13 t.ha-1, respectively. With later flowering and longer cycles, sorghum biomass showed superiority to silagers in terms of plant size, PMV and PMS, with variability among them and the possibility of selecting the most productive and stable ones. In this regard, among commercial cultivars, despite similar plant heights, around 5 m, the hybrid BRS 716 was superior in productivity of green and dry mass to the giant Bolivian sorghum AGRI002-E in Cáceres environments (PMV = 89 t. ha-1 x 59 t.ha-1; PMS = 39 x 29 t.ha-1) and Nova Xavantina (PMV = 97 t.ha-1 x 73 t.ha-1; PMS = 31 t.ha-1 x 26 t.ha-1), similar in Sinop, with averages around 85 t ha-1 for PMV and 35 t ha-1 for PMS. Despite the significant GXA interaction for PMV and PMS, experimental hybrids 2 (201934B002) and 9 (201934B009) stood out, surpassing the commercial ones in stability being the most suitable for cultivation in the evaluated environments, whether for energy production or animal feed, since demonstrated high average yields of green matter (PMV = 95 t ha-1) and dry matter (PMS = 38 t ha-1), in addition to high phenotypic stability for these characteristics in different cultivation sites.

  • Mostrar Abstract
  • Safflower is an annual oilseed possessing oil with potential for use in several sectors, such as biodiesel production, pharmaceutical industry, paint manufacturing, besides ruminants feeding, since it is a product rich in linoleic and oleic acids and proteins. It is characterized as an oilseed plant for oil production, since this specie presents important characteristics such as simple management, similar to existing crops, high oil content, easy adaptation to Brazilian climate and also possibility of sub products generating from oil production to be used in animal feed. The present study evaluated the fatty acid profile of 120 safflower genotypes for oil quality, considering as evaluated characters palmitic, stearic, oleic and linoleic acid content. Means of each character were clustered by using Scott-Knott test (1974) at 1% probability. Considering all characters simultaneously, genetic divergence was estimated by Generalized Mahalanobis Distance (D²ii ́) and the most similar individuals were grouped by Tocher Optimization method and hierarchical grouping method UPGMA. The results indicated significant differences (p < 0.01) for all characters evaluated, evidencing the existence of genetic variability among studied genetic materials. Genotypes that stood out for the four variables analyzed were: PI 369842, PI 392031, PI 401474, PI 401475, PI 405975, PI 532639 and PI 613382. The genetic diversity of evaluated genotypes existing among the four fatty acids evaluated, combined with productive potential, suggests expressive expectations for obtaining promising genotypes in a safflower breeding program.

  • Mostrar Abstract
  • Brazil is the country richest in biodiversity, changing the greatest wealth in plant species. Bixa arborea and Bixa orellana, are two similar plant species, of the Bixaceae family, with wide distribution in South America, and widely used by the traditional population. The species of the genus Bixa have a pigment in the seeds, which has been used by the native populations of America for a long time, mainly in the ornamentation of the body and objects. Today it is known that this pigment and the leaves of Bixa arborea and Bixa orellana are rich in carotenoids, antioxidant compounds and vitamins. Mandatory to the high concentration of phytochemicals, Bixa orellana is widely used in the food and textile industry (as a dye) and in the pharmaceutical and cosmetic industry, in addition to being used as herbal medicines by the population. Bixa arborea besides phytotherapic use, is also widely used in forest restoration and as a source of wood. In this context, it is extremely important to differentiate genetically and morphologically B. arborea from B. orellana, through the taxonomic description of the species and the quantification of nuclear DNA of the species, further expanding the knowledge about these species. It also sought to analyze whether there was a morphological and genetic difference between B. arborea specimens, to find out if there were hybrids in the analyzed population. For this, the biometrics of the fruits and the morphological description of the two species were carried out at the Laboratory of Cytogenetics and Tissue Culture and at the Herbarium of the Southern Amazon of the University of the State of Mato Grosso, Alta Floresta campus, in addition to analysis of the DNA content through flow cytometry. From this, it was possible to perceive that the two species present many anatomical similarities, basically differing one another by the aspect of the fruit: B. arborea presented papulous fruits or partially covered by non-flexible spines with length varying from 0.1 to 1.8 mm, while B. orellana presents fruits completely covered by flexible spines and with length varying from 4 to 9.6 mm. The average amount of seeds in the fruits of B. orellana was higher than that found in the fruits of B. arborea. The specimens of B. arborea columns point morphological differences, such as greater number of flower stamens (phenotype 3), presence of thorns in the fruit (phenotype 5 and 6), absence of thorns in the fruit (1 and 2) and presence of fruit with long mucronatiform apex, being the only phenotype with this characteristic. The amount of nuclear DNA showed a difference between the two species and neither between those belonging to B. arborea, however this difference was not summarized. This shows that the species are very close genetically and, therefore, very related. Thus, we can conclude that the two species have difference mean the size of the genome, with the shape of the fruit and the quantity of seeds being the most suitable to separate the two species.

  • Pre-breeding of balsa stick (Ochroma pyramidale Cav. Ex Lam. Urb.)

  • Data: 04/03/2021


  • Mostrar Abstract
  • The balsa stick is a native species of the Amazon, occurring in Brazil and neighboring countries, having as a characteristic low density of wood, being used in the nautical and aeronautical industries. However, its use is not restricted only to these areas, but occurs from the furniture industries to medicinal purposes. Due to their characteristic of rapid growth, foresters in the state of Mato Grosso implemented commercial crops, but with seedlings without selection and standardization and little information on the crop. In order to promote the pre-improvement of the crop, the objective of this work was to estimate the basic density of the wood in situ, to evaluate the phenotypic variability among individuals planted in Mato Grosso and to validate proposed vegetative propagation techniques for the species. To predict the density of the wood, Pilodyn equipment was used on 20 adult trees. From each individual, three sampling points were determined: at the base of the trunk, at 1.30 m and 3.10 m, on the north and south sides of the tree. The use of Pilodyn for the prediction of the basic density of the wood in the balsa stick proved to be efficient and applicable when performed at 1.30 m in height. For the selection and phenotypic divergence, 70 individuals of balsa stick, seeds from Brazil and Ecuador were selected. The following measures were obtained: total height of the individual, DBH and basic wood density. The Euclidean dissimilarity matrix and the Toucher optimization method were performed. Variability was found between individuals, with the formation of nine different groups using the Toucher optimization method, with emphasis on genotypes A09 and A14, both of Ecuadorian origin. For vegetative propagation, 240 cuttings were selected from 10 pre-selected matrices. The treatments were carried out with different concentrations of AIB, in DIC, with 4 repetitions. The percentage of survival, calluses and root formation after 60 days were analyzed. It was found that after this period, the treatments did not obtain a significant response to root formation, and presented low survival, making the vegetative propagation of balsa stick unfeasible by cutting. Analyzing the research for the pre-breeding of the species, Pilodyn is indicated for in situ assessment of the wood density at 1.30 in height and that the analyzed plantations present phenotypic variability, with emphasis on trees of Ecuadorian origin. However, vegetative propagation through cuttings proved to be unfeasible for the species.

  • Mostrar Abstract
  • In Brazil, the cultivation of pineapple has grown considerably, but fusariosis, considered as the main disease of this culture, has been causing high losses in production. Thus, the present study aimed to evaluate the efficiency of resistance inducers applied in cultivars to control pineapple fusarium disease, as well as to verify their influence on the vegetative characteristics of the cultivars. The treatments were used: T0 - absolute control; T2- acibenzolar-S-methyl (ASM) 0.4gL-1; T3- Bacillus subtilis 1x109 UFC mL-1; T4-ecolife® 0.2 mL-1; T5- acibenzolar-S-methyl (ASM) 0.4gL-1 + Bacillus subtilis 1x109 UFC mL-1 + and T6- ecolife® 0.2 mL-1 + Bacillus subtilis 1x109 UFC mL-1. The experimental design used was randomized blocks in a 6x2 factorial arrangement (6 treatments and two cultivars (one resistant and the other susceptible), containing 3 replicates, each plot with 5 plants, in which the same plants were used for enzymatic analysis, as well as to analyze the severity of the disease, two plants of each replicate per cultivar were used to evaluate the dry matter. The collections for enzymatic analysis of peroxidase, polyphenoloxidase, phenylalanine ammonia lyase, β-1,3-glucanase and total proteins were performed at 24, 48, 72, 96 and 120 hours after inoculation of Fusarium guttiforme. All inductors evaluated provided increases in the activity of peroxidase, polyphenoloxidase, β-1,3 glucanase and phenylalanine ammonia lyase, but only ASM, PBC and Bacillus subtilis + PBC were efficient in controlling fusariosis, in addition, the plants of the resistant cultivate (BRS Imperial) showed less severity and less Area Under the Curve of Severity of Disease Progress (AUDPC) when compared to the plants of the susceptible cultivate (Pérola). All inductors provided an increase in the dry mass in the aerial part to cultivate Pérola. There was no influence of inductors on the other vegetative characteristics evaluated.

  • Mostrar Abstract
  • The mung bean lines, selected by the breeding program of Embrapa Meio-Norte, are evaluated in the state of Mato Grosso during the off season to assess the adaptability and stability of production and other phenotypes of agronomic interest. In this work, the objective was to evaluate the response of lines to grain yield by applying fertilizers. The experiments were installed with and without application of fertilizer, with two tests per site, with the same lines, varying only the application of fertilizer, one without application (zero fertilizer) and the other with application of the formulated NPK 0-20- 20 in the sowing furrow and 45 kg / ha of nitrogen in cover, 25 to 30 days after emergence. The doses were defined considering the soil analysis at each location. The experiments were conducted in Sorriso-MT 2019, Sorriso-MT 2020, Sinop-MT 2019 and Sinop-MT 2020, totaling four trials without fertilizer and four with fertilization. Before sowing samples were collected composed of soil from the 0-0.20m layer, for physical, chemical characterization and interpretation of soil fertility. The tests consisted of eleven treatments, ten pre-commercial lines and one control. The experimental design was the DBC, with 3 replicates, plots of 2 lines of 4m in length and 0.50m spacing. The cultivation value, the length of the pod, number of grains per pod, the mass of 100 grains, grain yield and the grain index were evaluated. In general, a significant effect was observed between strains for all evaluated characteristics, indicating the presence of variation between them. The interaction between treatments and environments was not significant, indicating that there was no change in the classification of strains, regardless of whether the environment was fertilized or not. The strains that showed the best response to fertilization were BRA-000027 (MV4) and BG3 (MV10). The strain BRA-000027 was the one with the best general adaptability and also the best for unfavorable environments. The BG3 strain showed the best adaptability to favorable environments.

  • Mostrar Abstract
  • The characterization and evaluation of genetic resources are essential for the development of new cultivars by breeding programs. Among the activities carried out, it highlight the morphoagronomic and reproductive biology studies. Therefore, this study aimed to carry out a morphoagronomic, phenological characterization and estimate the pollen viability of thirteen bean varieties under the conditions of the city of Alta Floresta-MT. The experiment was conducted at the DIC consisting of thirteen treatments (PV01, VU02, VU03, VU04, VU05, PV06, VU07, PV08, PV09, VU10, VU11, VU12, PL13) and ten repetitions. The morpho-agronomic characterization was performed using descriptors of plants, leaves, flowers, fruits and seeds. The data obtained were evaluated using descriptive, uni and multivariate statistics. Only violet and white flowers were observed. Most varieties had small seeds with different colors. The analysis of variance showed significant differences at 1% probability for all quantitative characteristics evaluated. The number of days for flowering and physiological maturation were the characteristics that presented more groups formed by the Scott & Knott average cluster test. The UPGMA and Tocher clustering methods agreed to separate the varieties into three groups and according to species. The canonical variables revealed that the first two characteristics explained 100% of the total variation and separated the varieties into five groups. The characteristics that most contributed to the genetic divergence were: number of days for flowering and physiological maturation. In the evaluation of the phenological phases, a scale of notes established for common beans was used and applied to all varieties. The flowering rate, peak flowering and pollen viability were estimated using the Alexander dye. The vegetative and reproductive development of the thirteen bean varieties ranged from 22 to 36 days and 36 to 59 days respectively. Varieties with a longer reproductive period took longer to complete the development cycle. The genotypes PV06 and PV08 both of determined growth and belong to species P. vulgaris are the earliest, while the VU05 variety of undetermined growth took longer to complete the cycle. The highest peak and flowering rate was obtained by the PL13 genotype, and all varieties had a high percentage of viable pollens. It is concluded that the thirteen bean varieties have genetic variability and potential genetic resources to be conserved and used in breeding programs. In addition, it is essential that studies be expanded to increase knowledge of the existing local variability.

  • Mostrar Abstract
  • The identification of genotypes with high production potential and with broad stability and adaptability is one of the main targets of maize breeding programs (Zea mays). That is why, before being recommended to farmers, these genotypes are evaluated in multi-environmental tests. The objective of this work was to evaluate the adaptability and stability of corn hybrids in six environments in the North of Mato Grosso and Southeast of Rondônia. For this, 36 simple corn hybrids were evaluated in six environments, namely: Vilhena-RO, Sorriso-MT, Alta Floresta-MT, Carlinda-MT and Sinop-MT, since the latter was evaluated in two years of production (2017/2018 and 2018/2019), thus totaling six environments. The experiments were outlined in a square lattice (6x6) and in 2 repetitions. Each experimental plot was composed of two rows of four meters long, spaced 0.7 m apart, making a total of 144 experimental units (36x2x2). The PG was obtained by weighing the threshed grains from each plot, afterwards, the data were subjected to stand correction, from the analysis of covariance with correction for ideal stand, corrected to 13% humidity and converted to kg.ha-1. Stability and adaptability were assessed using the methods of Annicchiarico (1992), Lin & Binns (1988), Eberhart & Russel (1966) and AMMI using the Genes program and for the REML/Blup method, the Selegen software was used. There was a significant difference (p <0.01) for the effects of environments and GXA interaction. The Annichiarico methodology revealed the environments of Vilhena-RO, Sorriso-MT and Alta Floresta-MT as the favorable cultivation environments and the 1P2255 genotype with adaptability in all cultivation environments. The method proposed by Lin & Binns, on the other hand, revealed the genotypes DKB310, 1P2247, 1L1411, 1P2215, 1P2267 and 1M1782 showed adaptability to general environments. For the Eberhart & Russel method, the genotypes with high average grain yield, broad adaptability and high stability were 1O2112, 1P2203, 1P2184, 1P2212, 1P2255 and 1P2231. The AMMI method identified the 1P2255 genotype as more productive and also more adapted and stable for the evaluated environments. The REMEL / Blup methodology indicated the genotypes DKB310, 1P2247, 1L1411, 1P2255, 1P2215, 1P2214, 1M1782, 1P2267, DKB390, 1M1807, 1N1958, 1P2184 and 1P2231 as the most stable, adaptable and with the best productive performances. The methodologies of Annicchiarico, Eberhart & Russel, AMMI and REMEL/Blup showed similar results in the classification and recommendation of hybrids1P2255 with wide adaptability. However, there was a divergence in the indication of hybrids with specific adaptability to favorable and unfavorable environments.

  • Mostrar Abstract
  • The commercially planted forests of Tectona grandis L.f have been increasing in the state of Mato Grosso, due to the edaphoclimatic conditions that favor the vegetative development and mainly the gain in productivity of m3 / ha / year. These conditions also provide the appearance of several diseases and one that deserves mention is the fungus of the genus Ceratocystis, which initially colonizes the vascular exchange of the plant between the bark and the wood and prevents the passage of sap, causing the death of the tree. However, there are few genetic improvement works aimed at the selection of material with resistance and susceptible to diseases. In this sense, the work was to evaluate the genetic variability of 37 clonal teak genotypes in a greenhouse after inoculation of the pathogen isolate. The experimental design used was randomized blocks, with 3 replications and each plot composed of 3 plants, totaling 333 units. The seedlings were evaluated 120 hours after inoculation of the fungus Ceratocystis fimbriata for alternate days until completing 126 days, where the variables were measured: total height of the plant, diameter of the neck and the sizes of the lesions made by photogrammetry. However, being found different forms of manifestation of the pathogen in the genotypes, a large patch moving between the medulla and the conducting vessels, another with risks distributed linearly and randomly through the shaft, and an ellipse.

  • Mostrar Abstract
  • The balsa tree (Ochroma pyramidale Cav. ex Lam. Urb) belongs to the Malvaceae family, and is a perennial tree species which is native to South and Central America. The species is widely used in the recovery of degraded areas and its harvesting has proved to be a productive activity of economic value for the production of low density wood. However, knowledge regarding the reproductive aspects and genetic diversity of this species is scarce. Therefore, this study aimed to analyze aspects of reproductive biology and evaluate the genetic diversity of populations of O. pyramidale cultivated in the state of Mato Grosso, Brazil. For analyses related to reproductive aspects, flower buds at different stages of development were collected in the municipalities of Sinop, Itaúba and Alta Floresta, Mato Grosso, and were used to study palynology, meiotic index, cytochemistry and pollen viability. For the genetic diversity investigation, PCR reactions were performed with 15 ISSR primers, using DNA extracted from young leaves of 60 individuals of O. pyramidale, which were collected from three populations in the municipality of Guarantã, Mato Grosso. The results demonstrate that the pollens of O. pyramidale are of the suboblat type, triporate, large, have a large polar area and sexine with reticulated ornamentation. The species has a high percentage of viable pollen, regular meiotic index and has starch and lipid as storage substances in pollen. ISSR primers amplified a total of 111 loci, of which 97.3% were polymorphic. The values of genetic dissimilarity obtained from the complement of the Jaccard index ranged from 0.17 to 0.79, not showing identical individuals in genetic terms. The genetic diversity of Nei (0.32) and Shannon Index (0.48) for the species is indicative that there is genetic diversity among the 60 individuals studied. AMOVA revealed that 71% of the total genetic variation is found in populations while 29% among the evaluated populations. The ISSR molecular markers were efficient in analyzing the genetic diversity of the 60 individuals of O. pyramidale, and can be considered promising sources of genetic resources for selection and use in breeding programs. Furthermore, the study enabled the expansion of knowledge regarding the reproductive aspects and the genetic diversity of O. pyramidale, which is useful information both for conservation of this species, as well as for breeding programs.

  • Mostrar Abstract
  • Tropical floriculture is an activity that is on the rise in Brazil, the sector of production and marketing of ornamentals has shown continuous growth in recent years. The unique Heliconia genus belonging to the Heliconiaceae family, stands out in this branch for containing bracts in different shapes and colors. The state of Mato Grosso has a favorable climate for cultivation in full sun or half shade and also provides numerous diseases, including anthracnose, caused by species of the genus Colletotrichum which interfere in the production, development and quality of this culture. In this sense, the purpose of this study is to induce resistance in the control of Colletotrichum sp. in Heliconia psittacorum x spathocircinata cv. Golden Torch of the Active Germplasm Bank of Tropical Flowers at the State University of Mato Grosso Carlos Alberto Reyes Maldonado. Heliconia psittacorum x spathocircinata cv. Golden Torch, grown in full sun and half shade. Two resistance inducers used together, a biotic inductor Bacillus subtilis and an abiotic, the product Acibenzolar-s-methyl (ASM), were used. In the evaluation, severity of the disease was observed, as well as the analysis of peroxidase and β-1,3-glucanase. The inducers reduced the severity of the disease in both cultivation conditions, with shading plants having the greatest reduction in severity. There was an increase in the production of peroxidase and β-1,3-glucanase. In the leaves and inflorescences of Heliconia psittacorum cv. Golden Torch of shading showed greater peroxidase activation when compared to plants in full sun. The activity of β-1,3-glucanase was verified in all plants regardless of the cultivation condition, with emphasis on the leaves grown in half shade where they showed activation during all the days of analysis.

  • Mostrar Abstract
  • Common beans (Phaseolus vulgaris L.) are of great importance in the global diet due to their low cost and nutritional quality. Several factors limit the production of the crop, especially the disease called white mold, caused by the phytopathogen Sclerotinia sclerotiorum (Lib.) De Bary. Among the most suitable control methods, which offer greater savings and less risk to the environment, is the use of resistant cultivars, through genetic resistance. Thus, this study aimed to identify sources of resistance to white mold among common bean cultivars of Andean and Mesoamerican origin. The experiment was carried out in a greenhouse and in a laboratory in a Randomized Block Design (DBC) with six replications and two inoculation methods, the straw test straw inoculation method, with 109 genotypes. The experiment was carried out at the State University of Mato Grosso, Cáceres and at the Laboratory of Genetic Resources and Biotechnology also in Caceres, Mato Grosso, between the months of March and May 2019. It was used by UFV-Ss493, grown in BDA (Potato Dextrose Agar) poured into 90 x 30 mm Petri dishes, stored in the BOD chamber (Bioclimatic Oxygen Demand) with a temperature of 23 ° C and a photoperiod of 12 hours. The inoculation method can consist of inoculated plants 21 to 28 days after planting, cutting with sterile scalpel at the point of growth of the plant below the second well-developed trefoil. While the seedling test uses plants for 15-day inoculation, cutting with a sterilized scalpel at the point of growth of the main stem of the plant below the first trefoil and displaying a mycelium disk followed by the protection of a 200 ul bridge. Variables of lesion length and scores were observed every two days. There was a significant difference in all variables, such as the cannula inoculation method and the cannula inoculation method. The genotypes BGF 205, BGF 203, BGF 200 and BGF 67 were considered the most resident when compared to the other bean materials used in this work. Therefore, these genotypes can be considered as a source of resistance to the pathogen that causes white mold in the improvement protocols of common beans.

  • Mostrar Abstract
  • The safflower culture has stood out for presenting excellent quality and high oil content in its seeds, which can be used in industries with different purposes, such as for food and pharmaceuticals or for the production of energy by biodiesel. Brazil is an important producer of biodiesel and has favorable edaphoclimatic conditions for the cultivation of safflower. As it is a drought-tolerant plant and presents resistance to water deficit, its cultivation can be indicated in conditions with reduced humidity, such as in the second harvest period for the Midwest region of Brazil. In view of the above, this study aimed to evaluate 122 safflower genotypes from the Germoplasm Active Bank (BAG) of the Instituto Mato-Grossense do Algodão (IMA-MT), based on the oil content and chemical analyzes, in order to identify accesses with superior characteristics in relation to oil, by means of multivariate analysis, aiming to expand information on this culture. The characteristics analyzed were: oil content; acidity level; iodine index and saponification index. The data were subjected to analysis of variance and multivariate analysis based on the generalized Mahalanobis distance to estimate genetic divergence, using the Tocher grouping method, UPGMA, canonical variables and relative importance of the characters. The results indicated significant differences (p <0.01) for all variables analyzed, showing the existence of genetic variability between safflower genotypes. The genotypes PI 369845 and PI 401589 showed greater genetic divergence (= 946.00), and the clusters generated by the method of Tocher's optimization, UPGMA and graphic dispersion showed similarities in the clusters of genotypes. The first two canonical variables were sufficient to explain 90.87% of the total variation and the variables oil content and acidity level obtained the greatest contribution to genetic divergence, demonstrating that among the 122 accessions evaluated there is wide genetic divergence.

  • Learning becomes more captivating as new content is incorporated into knowledge structures in students' daily school life. With this, they acquire meanings for studies from the relationship with knowledge in practice. The Inga genus has a great diversity of species, known on average 300 species of the Neotropical genus, having great diversity in the Amazon Forest. This work had as objective, a practical class on the cell division (Mitosis), with the visualization and identification of the plant cells of Allium cepa by the students of the 2nd year of high school and Behavior of the cell cycle of Allium cepa L. through the cytotoxic potential , genotoxic and antiproliferative of infusions of leaves of Inga edulis, Inga pilosula, Inga laurina and Inga macrophylla. For the study, theoretical and practical classes were held with students in the Didactic laboratory. For laboratory analysis, four plant species of the genus Inga were used. The test organism used was Allium cepa bulbs. The infusions were obtained from the dry leaves of Inga edulis, Inga pilosula, Inga laurina and Inga macrophylla collected during the dry and rainy season.
    With the results obtained, it was found that practical classes are considered of great importance in the teaching-learning process. When teaching the theoretical class and then applying the questionnaire, statistical data was obtained below 60% of correct answers in the identification of mitotic cells. However, after the theoretical and practical class, and applying the same questionnaire, a statistical percentage above 80% of correct answers in the identification of mitotic cells was obtained. According to the analysis of Allium cepa cells, using the Direct and Indirect Method for both periods, exposed under the infusions (1g, 1.5g 2g) of the dried leaves of Inga edulis, Inga pilosula, Inga laurina and Inga macrophylla, obtained considerable statistical differences between the two Methods. The species I. edulis, I. laurina and I. macrophylla showed the highest rates of cell division. With regard to the Anomaly Index (ÍA), the Indirect Method obtained the highest rates of abnormal cells for both species. For the Interphase Percentage, the Direct method obtained the highest percentages of interphasic cells. These data, when compared with the negative and positive controls, showed lower and higher percentage results, with a statistical difference between treatments. This study showed that the four species, had genotoxic and cytotoxic effects under the roots of Allium cepa

  • Mostrar Abstract
  • The general objective of the work was the in vitro production from somatic embryogenesis using the endosperm, morpho-agronomic characterization and evaluation of the behavior of triploid plants in the production of resistance enzymes in Passiflora cincinnata. For the production of triploid plants via somatic embryogenesis, mature endosperm from the seed of P. cincinnata is used. The highest average of somatic embryo production was observed in the supplementation treatment with 18.1 μM of 2.4-D + 4.5 μM of BA, with an average number of nine embryos per explant at 30 days of culture. Seedlings regenerated in vitro for 45 days were grown at home and a confirmed ploidy level with a DNA amount of 4.38 pg and chromosome number 3n = 3x = 27 and the respective diploids (2n = 2x = 18). The flowering of the triploid plants occurred at 210 of cultivation and showed high variability in phenotypic expression due to the genetic variability provided by the increase in ploidy. Diploid and triploid plants described polymorphism (77%) in the morpho-agronomic descriptors. As the triploid plants exhibit heteromorphic leaves, predominantly trilobed with larger size and darker tonal width. The flowers were bigger, darker and more intense, with a predominance of purple color. The diversity of flowers found in triple plants, seven changes, suggests that the addition of ploidy causes changes in the expression of genes and causes the occurrence of phenotypically variable colorings of flowers, improving the ornate patterns of the species. The internal and external diameter of the crown cavity increased in the triploid plants. The fruits of the triploids had smaller width and number of seeds/fruit and greater length and thickness of the peel compared to diploid. Pollen analysis data show that diploid and triploid species have high rates of pollen viability, 98.21 and 97.82%, respectively. Physiological changes in the production of oxidative (peroxidase and polyphenol oxidase) and hydrolytic (β-1,3-glucanase) enzymes were observed in the triploid plants of P. cincinnata. The increase in ploidy affected the activity of enzymes used in plant resistance. As plant growth-promoting rhizobacteria, A. brasilense and B. subtilis, were used in the activation of enzymes related to the resistance and plant defense mechanisms in diploid and triploid plants. A. brasilense provided the highest values of activity induction of the enzymes peroxidase and polyphenol oxity and B. subtilis induced greater activity of β-1,3-glucanases in P. cincinnata. The ability to respond to the defense mechanisms of triploid plants produced in vitro with the use of Pcincinnata endosperm and the induction of biostimulants in the production of resistance enzymes, opens new approaches in the genetic improvement for the genus.

  • Mostrar Abstract
  • The objectives of this research were to overcome the dormancy of seeds of Passiflora alata and Passiflora cincinnata MAST. as well as to evaluate the internal and external morphology of P. cincinnata seeds by X-ray test and image analysis using GroundEye® software, aiming to relate the seed morphology to their respective maturation stages and to establish the ideal moment for collecting fruits, associating with the quality of the seeds. To overcome dormancy, the pre-germinative treatments were: imbibition in Fluridone® in concentrations of 0,1; 10 and 100 µM, for 12, 24 and 48 hours; soaking in Promalin® in concentrations of 0,03; 0,45, 0,90 and 2%, for 6 and 12 hours. The treatments were distributed in DIC, with four replications of 25 seeds. Germination, meantime, germination speed index, germination uncertainty and synchrony were evaluated. The results revealed that in seeds of P. alata, Promalin® at a concentration of 0,90% in 12 hours of imbibition, guaranteed better germination results, average germination time and germination speed index. For seeds of P. cincinnata, treatment with Promalin® is effective at a concentration of 2% for 6 hours, promoting an increase in germination and the rate of germination speed. To perform the X-ray test and image analysis using the GroundEye® software, four replications of 50 seeds were used for each stage of ripening of the fruit of P. cincinnata (green, “from time to time”, mature and senescent). The seeds submitted to X-ray exposure were classified as full or empty. GroundEye® equipment was used for computer image analysis, evaluating 15 descriptors related to color dominance and 7 geometry. Subsequently, the seeds were evaluated for germination percentage. From the X-ray test, it was found that there was no statistical difference between the maturation stages. The results obtained by the GroundEye® software indicate differences in color and geometry between the fruit ripening stages. It is concluded that the seeds of P. cincinnata can be collected from fruits in the mature and senescent stages without prejudice to the physiological quality.

  • Mostrar Abstract
  • In the culture of passion fruit, seeds are considered the main form of propagation, the species of passion fruit besides having seeds with different biometric aspects, also have different dormancy mechanisms. For the following work seeds of the Passiflora eichleriana, Passiflora nitida and Passiflora mucronata species were used, submitted to biometric analysis where data were submitted to descriptive statistical analysis to determine the mean (M), median (MD), kurtosis (K), standard deviation (DV), coefficient of variation (CV), maximum (MAX) and minimum (MIN) and data amplitude (AMP), and after biometric analyzes were submitted to germination test after treatments to overcome dormancy, obtaining the germination percentage (%), average germination speed (VMG) and average germination time (TMG). With the biometric analysis of the data, we can conclude that the seeds of the analyzed species vary in height, length and thickness, not only within the species, but when compared with other species of the same genus. In overcoming dormancy, it was observed that for the P. crisp species the highest percentage of germination was observed in the treatments with GA3 dosages: 2000 mg L-1, 3000 mg L-1, 4000 mg L-1 during 6 hours of soaking and 4000 mg L-1 during 12 hours of soaking, and also in treatments with dosages of 4500 mg L-1 and 9000 mg L-1 of Promalin® during 12 hours of soaking. For P. eichleriana, the seeds showed higher germination percentages in the soaking treatments in 9000 mg L-1 solution of Promalin® during 6 hours of soaking and 4500 mg L-1 and 9000 mg L-1 of Promalin® during 12 hours of soaking. For the species P. mucronata it is observed that the treatments 4500 mg L-1 and 9000 mg L-1 of Promalin® during 12 hours of imbibition and 2000 mg L-1, 3000 mg L-1, 4000 mg L-1 during 6 hours of soaking and 4000 mg L-1 for 12 hours of soaking show better germination percentages.

  • Mostrar Abstract
  • Parkia pendula (Will.) Benth. ex Walp., popularly known as Angelim Saia, is a native species of the Amazonian upland and lowland forest, very important for the recovery of degraded areas, due to its rapid growth and for having a high survival rate in clearings. It has an ecological function in the recovery of degraded areas because it is a rapidly growing climatic species in open environments, by nitrogen fixation and by attracting wild animals. The inadequate exploitation of natural resources has been causing the extinction of a large number of species in the different biomes of the planet. Among the various causes of these extinctions, the most common are habitat loss and fragmentation. In view of this reality, there is an urgent need for genetic studies at the population level, so that strategies for managing and conserving genetic species can be established. Biometric studies help to determine different phenotypic parameters among individuals in a population, and are important instruments in the detection of genetic variability in populations of the same species and also in the inference of the relationships between variability and environmental factors. Therefore, this chapter aimed to characterize the biometry of fruits and seeds of the Parkia pendula forest species from different matrices in the North of the State of Mato Grosso and to evaluate the genetic divergence between the matrices, in order to obtain data to serve as a subsidy for future research related to the conservation of the species.
