Effect of sodium dodecyl sulfate (SDS) and hydrogen peroxide (H2O2) foliar spraying on photosynthetic pigments; chlorophyll a (Chl a), chlorophyll b (Chl b), carotenoids (Carot) and Chl a/ b of Juncus acutus plantlets 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
