Effect of AMF on antioxidant enzymes in the third fully expanded leaves of peanut plants under stressful conditions. The peanut seeds were inoculated with/without AMF before exposing to normal/salt/drought/cold growth conditions. The activities of (a) superoxide dismutase (SOD), (b) guaiacol peroxidase (G-POD), (c) catalase (CAT), and (d) ascorbate peroxidase (APX) were measured on the 8^th day after the onset of stress treatments. Bars represent the mean values of three biological replicates with standard deviation; asterisks indicate a significant difference in comparison to non-AMF according to Tukey's test (P < 0.05)
