| Abstract: | Objective] This work was aimed to explore the mechanism of Hg2+ toxicity on plants. Method]Activities of peroxidase(POD), catalase (CAT) and superoxide dismutase(SOD) were investigated in wheat (Triticum aestivum L. )seedlings under Hg2+ stress at different concentrations. Re-pared to POD and SOD. Conclusion] The toxic effect was related to the concentration of Hg2+ (0.10 mmol/L). The higher concentration of Hg2+ could affect the expression of POD, CAT, and SOD isozymes in the leaves, roots of wheat seedlings and germinated seeds, which further affect the normal metab-olism of membrane lipid and inhibit the growth of wheat seedlings at last. |
