Measurements of physiological indices for different groups across drought stages: (A) Leaf RWC; (B) H₂O₂ level; (C) Proline level; (D) Malondialdehyde (MDA) level; (E) Abscisic acid (ABA) level; (F) Salicylic acid (SA) level; (G) Gibberellic acid (GA3) level; (H) Indole acetic acid (IAA) level; (I) Catalase (CAT) activity; (J) Superoxide dismutase (SOD) activity; (K) Ascorbate peroxidase (APX) activity; (L) Glutathione reductase (GR) activity. Comparisons were performed using ANOVA with Duncan’s multiple-range test. c1, c2, and c3 on the x-axis indicate the three stages at 3 days (D1), 5 days (D2), and 7 days (D3) after the water deficit, respectively
