RESUMO

The objective of the present work was to study the relationships among the variations in the initial hydration, size and on physiologic quality of soybean seeds. Three lots (cv.BRS-157) with different physiologic quality had the seeds standardized according to thickness (13/64 inches) and submitted to hydration at 20ºC in variable periods (3, 6, 9 and 12h). After the hydration, the seeds were classified according to thickness and subsequently the individuals frequency in each fraction was estimated, submitted to evaluations of the physiologic quality. The physiologic quality was verified to affect the water content and the thickness reached by the soybean seeds during the hydration; therefore, it is possible to compare the relative physiologic quality of lots through the thickness frequency data in moisturized seeds.
