Résumé:
Soybean cultivation (Glycine max (L.) Merrill) is of great economic and social importance,
being one of the main commodities exported by Brazil. Cultivation requires specific
environmental conditions to achieve maximum productivity. Obtaining a satisfactory crop
depends on the use of high quality seeds, the evaluation of which is crucial to the success of the
agricultural enterprise. The objective of this work was to evaluate different batches of soybean
seeds based on physiological quality and vigor tests. 10 lots of soybean seeds were used,
identified as lots 100, 101, 110, 118, 120, 131, 144, 207, 336 and 447, obtained through
collaboration with a commercial company, from Uruçuí - Piauí. Germination, accelerated aging
and tetrazolium tests were carried out. The design used in the experiment was completely
randomized (DIC). The physiological tests consisted of ten lots, four replications of fifty seeds.
The evaluated lots presented satisfactory physiological quality conditions, storage resistance
and germination capacity, with vigor levels and were classified as medium and high quality
seeds. Therefore, evaluating the physiological quality of soybean seeds is essential for
increasing productivity.
