Abstract
[Objective] The impact of the copper,zinc and chromium on the antioxidant enzymes of rice seedling was investigated.[Method] The rice variety-Jinyou 402 being taken as testing variety,the activity of SOD,POD,CAT and the content of H2O2 in the leaf of rice seedling,which was cultured in water solution with the concentration of copper,zinc and chromium of 10,20,30 and 40 mg/L for 10 days,were measured.[Result] The activity of SOD,POD,CAT and the content of H2O2 in the leaf of rice seedling were increased in the treatment with the concentration of copper and zinc of 10 mg/L and the activity of SOD,POD,CAT and the content of H2O2 in the leaf of rice seedling were gradually declined with the increment of treating concentration.The activity of SOD,POD,CAT and the content of H2O2 in the leaf of rice seedling were gradually declining trend in the treatment of chromium of 10-40 mg/L.[Conclusion] The toxicity of Cr to antioxidant enzyme in rice seedling was higher than that of copper and zinc.
