Data are presented as mean ± SE. Different superscripted letters (a, b, c, d) within a column indicate significant difference from each other in all combinations (Tukey's test, p<0.05). Symbols “*” and “§” indicate significant difference in a given column for EBL+Spd vs. EBL and Spd+EBL vs. Spd under Cr-stress, respectively (Tukey's test, p<0.05). GSH, glutathione; ASA, ascorbic acid; PL, proline; GB, glycine betaine; TP, total phenols.
