Abstract: Tobacco seedlings were inoculated with VAmycorrhizal fungi in natural soil.The results showed that compared with the control,the contents of nitrogen,phosphorus,potassium and chlorophyll,nitrate reductase activity,and protein in leaves were higher,malondialdehyde(MDA) and hydrogen peroxide(H2O2) decreased,while the activities of superoxide dismutase(SOD),catalase(CAT),and peroxidase(POD) increased.Meanwhile,seedlings were inoculated with two strains of ectomycorrhizal fungi respectively,and the above physiological indices trended the same changes.Moreover,the effect of strain Calvatia lilacina was higher than that of VAmycorrhizal fungi.
