摘要
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。
Effects of different storage temperature (-4℃,4℃ and room temperature) on five soybean varieties were reported in this paper. Results showed that storage temperature had remarkable impacts on seed vigour, permeability, enzyme activities of SOD and POD, soluble protein contents and esterase isozymes. After storage for eight years, the seeds of five varieties stored at -4℃ were still in good condition, they remained high seed vigour,enzyme activities of SOD and POD, and soluble protein contents. However,those stored at 4℃ showed noticeable changes in both seed vigours and their physiological reactions. The seeds at room temperature suffered heavy losses not only in seed vigours but also in physiological functions. The tolerance of soybean seed to different storage temperature might have something to do with its genetic characters.
