RESUMO:

In Brazil, the presence of L. theobromae causing cancer and even death in Tectona grandis was identified, in this 

sense the objective of this study is to carry out the characterization of Lasiodiplodia theobromae associated with

the damage caused in Tectona grandis and to identify the potential severity of the isolates collected in the state 

from Mato Grosso and Pará. The study will be divided into two stages, the first being conducted at the Laboratory 

of Plant Genetic Improvement with the morphological characterization of samples collected from symptomatic teak

 plants and isolated in culture medium with subsequent identification under an optical microscope, for cultural

 characterization of the isolates, will be An experiment was set up in a 6 x 3 x 2 factorial arrangement

 (temperature, culture medium, photoperiod) and every 24 hours the mycelial growth diameter (DM) will be 

measured, until the colony completely covers the diameter of the Petri dish, quantifying the number of conidia 

with the aid of a Neubauer chamber. In this way the average mycelial growth rate will be determined.

 The analysis  of variance and the means when significant will be compared by the Scott-Knott test with a 

probability of 5% using the Sisvar computer program. The second stage will be carried out in a greenhouse

with an aggressiveness and pathogenicity test of the different isolates inoculated in UNEMAT 33 genotype. 

The plants will be evaluated at 150 days after the fungus inoculation, the internal lesion length (CL) will be

 measured by longitudinal section. of the stem of the seedlings and evaluation of the lesion area (AL). The data

 obtained will be applied by the Scott-Knott test at the level of 5% of probability for the comparison of the 

means using the static program Sisvar.
