Effect of different concentrations of exogenous application of FeSO₄ (0, 50, and 100 µM) on non-enzymatic antioxidants and sugars, i.e., phenolic contents (A), flavonoid contents (B), ascorbic acid contents (C), anthocyanin contents (D), soluble sugar contents (E), reducing sugar contents (F), non-reducing sugar contents (G) and proline contents (H) in the leaves 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.
