Both upper and lower epidermis cells are polygonal or irregular in shape in all species studied. The patterns of anticlinal walls are straight, arched or sinuous, and the raphal cuticular striastriae are occasionally observed on periclinal walls.

干旱胁迫下，光合速率的下降是气孔因素与非气孔因素双重作用的结果：轻度干旱胁迫下（土壤相对含水量55%~40%）气孔限制是光合速率下降的主要原因，而严重干旱胁迫下（土壤相对含水量20%）非气孔限制是光合速率下降的主要原因。
