Fig 1. Effect of Fe and Cd interaction on root and shoot biomass (g).

Here, Fe and Cd indicates 0, 0.2, 0.4 and 0.6 mg L⁻¹ Fe as FeSO₄.7H₂O and 0, 10, 20 and 30 mg L⁻¹ Cd (supplied as CdSO₄). The data presented are mean ± standard deviation (n = 3). Mean values followed by different letter are significantly different using Duncan’s multiple range test at 5% level.
