摘要:
为探讨SO2对小麦幼苗主要细胞保护酶的影响，现采用酶活性测定技术，测定了SO2熏气处理后小麦幼苗体内过氧化氢酶、过氧化物酶、超氧化物歧化酶等酶活性的变化。结果表明：用50 mg·m-3的SO2熏气处理后，小麦幼苗叶片细胞中CAT和SOD的活性下降，POD的活性升高。因此，50 mg·m-3的SO2熏气处理对小麦不同细胞保护酶的影响是不同的，细胞保护酶活性的高低在SO2对小麦的伤害和小麦对SO2的抗性中可能具有重要的作用。
Abstract:
In order to explore effect of SO2 on mainly cell defense enzyme of wheat seedling,using assay of enzyme activities,the dynamic changes of catalase,peroxidase,superoxide dismutase activity in wheat leaves cells under 50 mg·m-3SO2 were determined.The results showed that CAT and SOD activity in wheat leaves cells were decreasing after being treated with 50 mg·m-3SO2,but POD activity increased immensely.So it concluded that SO2 had different effects on defense enzymes in wheat.The activity level of cell defense enzymes might play an important role in SO2 damage and resistance in wheat.
