Table 5.
Leaf type, mesophyll thickness, fias, mesophyll surface area exposed to intercellular airspace (Sm/S), chloroplast surface area exposed to intercellular airspace (Sc/S), the ratio Sc/Sm, Tcw, Tcyt, Lchl and Tchl in Q. robur and Q. faginea leaves. Data are mean ± SE. Different letters indicate statistically significant differences (P < 0.05) between Q. robur and Q. faginea.
