Effects of salt stress (SS) and alkali stress (AS) on relative growth rate (RGR) of leaves (a) and roots (b), net photosynthetic rate (P _N) (c), stomatal conductance (g _s) (d), intercellular CO₂ concentration (C _i) (e), transpiration rate (E) (f), chlorophyll a (Chl a) (g) and b (Chl b) contents (h), and carotenoid (Car) (i) content of wheat. Values are means of five replicates. Means followed by different letters in the same stress type are significantly different at p < 0.05 according to Duncan’s method
