Effect of different concentrations of exogenous application of FeSO₄ (0, 50, and 100 µM) on oxidative stress indicators, i.e., MDA contents in the roots (A), MDA contents in the leaves (B), H₂O₂ contents in the roots (C), H₂O₂ contents in the leaves (D), EL percentage in the roots (E) and EL percentage in the leaves (F) of Oryza sativa (cultivars) grown under different levels of Cd stress (0, 50 and 100 µM). Bars sharing different letter(s) for each parameter are significantly different from each other according to Duncan’s multiple range test (p < 0.05). All the data represented are the average of four replications (n = 4). Error bars represent the standard deviation (SD) of four replicates.
