Qualidade fisiológica e rendimento de grãos em função do local de produção de sementes

Abstract

This study aimed to evaluate the physiological quality of seeds and its influence on grain yield depending on the location of seed production. The experiment was conducted in Silvania in the state of Goiás with seed produced in the city Cascavel (Parana) and Silvania (Goiás) and that were used 8 seed lots of cultivar NA5909RG. The quality analysis of seeds were carried out in Germinax laboratory. The evaluations were: germination test, pre conditioned germination, first count, seedling emergence, plant height, productivity. The experimental design was completely randomized. Data were submitted to analysis of variance,and the effects of the treatments evaluated by F test and, when significant, the means were compared by Tukey test at 5% probability. The local production of seeds influences the physiological quality of the seed produced at the time of the resulting plants and grain yield.
