Cadmium effect on germination rate (a), root length (b), root fresh weight (c) and soluble protein content (d) in roots of faba bean seedlings, pretreated with 2% CaCl₂ (P) or H₂O (NP) for 6 h, and germinated for 7 days under 0 or 50 µM Cd. Values are the means of at least 12 replications ± SE. The data followed by different letters are significantly different at P ≤ 0.05
