(a) Photosynthetic assimilation of CO2 (A); (b) Substomatal concentration of CO2 (Ci) and (c) stomatal conductance (gs) of P. oleracea under treatment with 100 mM and 300 mM NaCl. Means ± SE; n = 3; one-way ANOVA with Tukey’s post hoc test; (a) F(8, 207) = 44.276; p = 0.0001; (b) F(8, 207) = 44.276; p = 0.0001; (c) F(8, 207) = 44.276; p = 0.0001. For each time point, the columns with different letters indicate significant difference at p < 0.05.
