Abstract
[Objective] The purpose of the research was to discuss the resistant mechanism of rice with different genotypes.[Method] The effects of organic acid and EDTA on the physiological and biochemical indices of rice in cadmium(Cd)-contaminated soil were researched through potting experiments.[Result] The activities of SOD in the rice in cadmium(Cd)-contaminated soil were enhanced significantly by using organic acid and EDTA separately and their mixture and the activities of POD and CAT and content of MDA in the rice were decreased significantly in comparison with that of Cd-contaminated controls.Compared with low Cd-contaminated controls,MDA contents of Xiushui63 in low Cd-contaminated soil were decreased by 7.5% and 16.4% resp.by using adding organic acid and EDTA.After the organic acid and EDTA were added,the content of free proline in rice was higher than that of Cd-contaminated controls and that in ⅡYou527 was higher than that in Xiushui63 in the same treatments.The change of root activity of Xiushui63 was less than that of ⅡYou527.In low Cd-contaminated treatments,the root activity of rice was decreased by adding organic acid and EDTA.In high Cd-contaminated treatments,the root activity of rice was enhanced significantly only by adding organic acid.[Conclusion] The activities of POD and CAT and the content of MDA in rice could be decreased significantly and its activity of SOD could be increased by using organic acid and EDTA.
