Fig. 1

Response of (a) net photosynthetic rate (Pn), b stomatal conductance (gs), c transpiration rate (Tr) and d intracellular CO2 concentration (Ci) to exogenous glycine betaine (GB) and salicylic acid (SA) under 150 mM NaCl regime. CK = Control; GB2.5 = 2.5 mM GB; GB5.0 = 5.0 mM GB; GB7.5 = 7.5 mM GB; SA1.0 = 1.0 mM SA; SA1.5 = 1.5 mM SA; SA2.0 = 2.0 mM SA; and ST = saline treatment (150 mM NaCl). All data are mean ± standard deviation. Differences between treatments having different letters above the error bars are significant at P < 0.05
