Fig. 4. Effects of drought stress on activities of SOD, POD, and CAT. (A) Changes in SOD activity. (B) Changes in POD activity. (C) Changes in CAT activity. Shown are the means ± standard deviation (n = 3). The asterisk indicates a significant difference (p <0.05) between drought-stressed and control plants (Duncan's singlefactor variance analysis).
