在水稻幼苗一叶一心期用质量浓度分别为６ ｍｇ·Ｌ－ １ 的ＳＯＤ（ 超氧化物歧化酶）模型化合物（ｓｕｐｅｒｏｘｉｄｅ ｄｉｓｍｕｔａｓｅ ｍｏｄｅｌｃｏｍｐｏｕｎｄ ；ＳＯＤＭＣ） 和１０ ｍｇ·Ｌ－ １ 的含锌复合物进行叶面喷施，结果表明：两种化合物均能相应提高低温胁迫后稻苗的ＰＯＤ（ｐｅｒｏｘｉｄａｓｅ） 和ＣＡＴ（ｃａｔａｌａｓｅ） 活性， 增加叶绿素、可溶性糖和可溶性蛋白质的含量，对冷害后幼苗生长的恢复、根系活力的增强有明显效果。
Leaves of rice seedlings were harvested at the leaf-one-leaf stage using leaves of SOD (superoxide dismutase model compound; SODMC) at a concentration of 6 mg · L -1, and 10 mg · L -1 of zinc- The results showed that both compounds could increase peroxidase and CAT (catalase) activities of rice seedlings and increase the content of chlorophyll, soluble sugar and soluble protein, and restrain the growth of seedlings after chilling injury, Increased root activity has a significant effect.
