  1. LL, Thickness of the leaf lamina; CT, Thickness of the cuticle of the adaxial surface; PP, Thickness of the palisade parenchyma; SP, Thickness of the spongy parenchyma; SCL, Number of sclereids in the mesophyll; AIS, Abundance of intercellular spaces in the mesophyll (Area/Area); SC, Number of secretory cavities near the central vein. All values are expressed as the mean ± standard deviation. Means followed by the same letter in rows (a, b) do not differ by the Scott-Knott test (P < 0.05).
