Fig. 3From: Physiological responses and proteomic changes reveal insights into Stylosanthes response to manganese toxicityAnalysis of antioxidant enzyme activities. SOD activity in leaves (a) and roots (b). POD activity in leaves (c) and roots (d). CAT activity in leaves (e) and roots (f). After 30 d of normal growth, stylo seedlings were treated with 5 or 400 μM MnSO4 for 10 d. Each bar indicates the mean of four biological replicates with standard error. The same letter represents no significant difference at the P = 0.05 levelBack to article page
