Effect of sodium dodecyl sulfate (SDS) and hydrogen peroxide (H2O2) foliar spraying on alternations in the capacities of enzymatic antioxidant: superoxide dismutase (SOD) and ascorbate peroxidase (APX) (a), and glutathione-s-transferase (GST) and polyphenol oxidase (PPO) (b) of Juncus acutus leaves and root grown in solution culture with increasing SDS concentrations (0, 50 and 100 ppm) treated or not with 15 mM H2O2. Values are the means of four replications ± SE. Variants bearing the different letters donate statistically significant at P > 0.05
