Effect of Chlorpyrifos Stress on Seedling Growth and Activities in Antioxidant Enzymes of Greengrocery

[Objective] The effect of chlorpyrifos stress on seedling growth and activities in antioxidant enzymes of greengrocery were studied.[Method] Pot experiments were conducted to evaluate effect of chlorpyrifos stress on soluble sugar and chlorophyll content,activities of SOD and CAT in Greengrocery.[Result] The results showed that Chlorpyrifos stress had a certain effect on the plant growth and antioxidant enzyme system.The soluble sugar content in plant decreased significantly by 78.56% compared to control;during seedling period,Chlorophyll a,Chlorophyll b,total chlorophyll,and carotenoids increased by 7.72%,8.72%,7.96%,and 4.52% separately;SOD activities increased by 50.2%,while CAT activities decreased 10.7%.[Conclusion] These primary research results wight provide the theoretic basis for the safe application of chlorpyrifos on vegetables.
