摘要：

The effect of NaCl stress on H2O2 metabolism in detached rice leaves was studied. NaCl (200 mM) treatment did not cause the accumulation of H2O2 and resulted in no increase in lipid peroxidation and membrane leakage of leaf tissues. The activities of peroxidase, ascorbate peroxidase, superoxide dismutase, and glutathione reductase were observed to be greater in NaCl-stressed rice leaves than in control leaves. However, glycolate oxidase was lower in NaCl-treated rice leaves than in the control leaves. There was no difference in catalase activity between NaCl and control treatments. These results suggest that some antioxidant enzymes can be activated in response to oxidative stress induced by NaCl.
