Qualidade das sementes de girassol de diferentes genótipos

The sunflower is one of the most important crops which produce edible oil, so the study was developed to evaluate aspects of the physical, physiological and sanitary seeds of different sunflower genotypes produced in the North of Minas Gerais. The seeds were evaluated using the following determinations and tests: water content, mass of 1000 seeds, seed biometrics (length, width and thickness), germination, first count, speed of germination, tetrazolium test and seed health, in a completely randomized design. In different genotypes observed uneven in size and mass of seeds and the genotypes SYN 034A, SY 3840, SY 4065, HLA 06270, M 734 and SYN 039A showed high vigor and viability, while the SYN 034A and SY 3840 showed low quality by the tetrazolium test. The fungi detected in seeds of different genotypes had low influence on the vigor and germination
