| 摘 要： | 以晋棉21、晋棉32、晋棉34等六个棉花品种为材料, 研究了人工高温、高湿老化处理对种子活力、以及幼苗下胚轴中过氧化物酶(POD)、超氧歧化酶(SOD) 活性以及丙二醛(MDA) 含量的变化的影响。结果表明:在高温(45±1)℃、高湿(相对湿度100% ) 密闭环境条件下, 随着老化处理时间的延长, 6个棉花品种的种子活力均表现为先升高而后逐渐降低的变化趋势。老化处理后发芽3d的幼苗下胚轴中POD、SOD活性的变化, 表现为单峰或双峰曲线, 而MDA含量受POD、SOD活性的影响, 与POD活性变化达到了极显著的负相关。

| Abstract: | The activity of seeds, the levels of POD, SOD and MDA content in hypocotyl of seedling were studied with six (JinMian21, JinMian32, JinMian34, Tai91995 and so on) treated with high and high humidity. The result showed that, in the closed circumstance of high temperature (45±1)℃ and high humidity (RH 100%), seed germination and activity of six cotton varieties raised at the beginning, then dropped off as the treating time went on. The changes of POD and SOD in aging three days hypocotyl took a single peak or a double peak curve pattern . The change of MDA content was influenced by the activities of POD and SOD significantly. |
