在长期贮存过程中，贮存温度对大豆种子的活力及细胞膜透性、ＳＯＤ和ＰＯＤ酶活性、可溶蛋白含量、酯酶同工酶等生理生化指标有明显影响。低温贮存种子活力保持较好，各项生理指标测定结果与之相吻合。在４℃条件下贮存，种子活力及生理生化指标变化较明显。常温贮存种子活力几乎全部丧失。大豆种子对贮存温度的敏感性可能与遗传特性有关 During long-term storage, the storage temperature significantly affected the vigor and membrane permeability of soybean seeds, the activity of SOD and POD, soluble protein content, esterase isozymes and other physiological and biochemical indexes. Low-temperature storage of seed to maintain better vitality, the physiological indicators measured results are consistent. Storage at 4 ℃, seed vigor and physiological and biochemical changes more obvious. At room temperature almost all the loss of seed storage. The sensitivity of soybean seeds to storage temperature may be related to the genetic characteristics
