| 摘 要： | 主要研究了在不同程度的土壤水分胁迫下“两优培九”功能叶抗氧化系统的变化情况。结果显示，在水分胁迫的前期，抗氧化系统中各成分的反应并不完全一致，SOD活性略有下降，而POD和CAT的活性则快速上升；AsA和GSH的含量不同程度地下降；脯氨酸和可溶性蛋白的含量均大幅增加。O2．- 的产生速率及膜脂过氧化产物MDA的含量始终

| Abstract: | The effect of water stress on the antioxidant system of the functional leaves were studied. The results showed that during the prophase of water stress, (1) the activity of SOD was descended slightly, but the activities of POD and CAT were enhanced; (2) the contents of AsA and GSH were reduced; (3) |
