RESUMO:

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.
