Physiological Responses and Tolerance of Halophyte Sesuvium portulacastrum L. to Cesium

Figure 5

Effect of cesium on antioxidant enzymes activity of S. portulacastrum: (a) superoxide dismutase (SOD), (b) catalase (CAT), (c) ascorbate peroxidase (APX), and (d) glutathione reductase (GR). All the values are mean of twelve readings ± S.E. One-way ANOVA significant at p ≤ 0.05. Different letters indicate significantly different values of antioxidant enzymes (DMRT p ≤ 0.05).
