Fig 1 — The effects of low temperature and drought stresses (25°C and 0 MPa, 15°C and -0.15 MPa) on the photosynthetic characteristics: (A) intercellular carbon dioxide (Ci), (B) net photosynthesis (Pn), (C) stomatal conductance (Gs), and (D) transpiration rate (Tr) of Brassica napus seedlings (varieties ZY15 and HY49). Seven different treatments (a) control (Ck), (b) water (H₂O), (c) salicylic acid (SA), (d) gibberellic acid (GA), (e) sodium nitroprusside (SNP), (f) calcium chloride (CaCl₂), and (g) abscisic acid (ABA) were evaluated. Each point represents the mean of three replicates. The values presented are the mean ± standard deviation (SD). Significant differences among treatments were determined using a three-way analysis of variance (ANOVA) (p < 0.05 according to Duncan’s multiple range tests).
