Abstract
Effects of the different concentration of Fe3+on membrane lipid peroxidation and activity of endogenous protective enzymes in tratary buckwheat(Fagopyrum tataricum(L.) Gaerth) were studied.The results showed that with the increase of the concentration of Fe3+,the contents of MDA in roots decreased at first then increased,the contents of MDA in leaves increased gradually;the activity of catalase(CAT) increased;the activity of peroxidase(POD) in roots increased then decreased,but the activity of POD in leaves increased;the activity of superoxide dismutatase(SOD) increased at first then decreased in roots,but increased in leaves;and the activity of cytochrome-oxidase(CO) decreased.
