Plants were subjected to 0 (0.5 dS/m), 25 (2.5 dS/m) or 50 mM NaCl (4.5 dS/m). Different letters indicate significant differences (P < 0.05) among the treatments at each salt level (a, b, c, d, e, f) or among salt levels for each treatment: T1 (A, B, C), T2 (D, E, F), T3 (G, H, I), T4 (J, K, L), T5 (M, N, O) or T6 (P, Q, R). Each value represents the mean of four replicates ± standard error (SE)
