【 摘 要 】

The objective of this study was to evaluate the physiological quality of the soybean seed during storage for 180 days at different moisture contents and two temperatures. Seeds of soybean, cultivar CD 242RR with initial moisture contents of 12, 13 and 14.0% (w.b.) were used. The seeds were acquired with a moisture content of 11.0% (w.b.), then were soaked in growth chamber at 20 ºC and 85% relative humidity, homogenized and packed in polypropylene bags. The vials were kept in two different environments. For the evaluation of seeds during storage analysis of moisture content, germination, speed of germination and electrical conductivity were conducted. The experiment was conducted in a completely randomized design, according to the triple factorial 2x4x3 (two storage conditions, four storage times and three levels of moisture) with three replications. The initial moisture content influenced the quality of soybean seeds during storage. The air-conditioned environment (20 ºC) provided better results in all the studied traits.
