Relationships between leaf thickness (LT) and stomatal conductance (gs), mesophyll conductance (gm), leaf hydraulic conductance (Kleaf) and leaf photosynthetic rate (A). The data points are the means ± s.d. of 3–5 biological replicates for LT, gs, gm and A, and of 4–8 biological replicates for Kleaf. Both linear and non-linear models were fitted, and the models with the lowest residual sum of squares are shown. Model equations: (A) gs = 4.14LT + 0.229, (C) Kleaf = 1.1e27.6LT and (D) A = 157LT + 14.5.
