Effects of PEN (0, 15 and 25 mg/L) pretreatment on fresh weight and dry weight of leaves (A), fibrous roots (B), and corms (C), leaves relative water content (RWC) (D), leaf carotenoids content (E), and leaves chlorophylls (Total Chl, Chl a, Chl b) content (F) of C. sativus L. under PEG (0, 5, 10 and 15%) induced drought. Dry weight of PEN treated corms increased significantly with increasing drought intensity. Vertical bars indicate means ± SE based on three replicates. Different letters above columns indicate a significant difference at P < 0.05 using Duncan multiple range test.
