leaf stoma

The mechanism of stoma and the differences of the correspondence of photosynthesis and transpiration to environmental changes were the physiological basis of WUE at leaf level.

气孔运动机制及光合作用和蒸腾作用对环境变化响应的差异是叶片水平WUE的生理基础；

The experiment indicated that, in the blast environment, the leaf layer relative humidity was reduced greatly, and that the air quality, the stoma conduct of leaf, dehydration rate, respiratory rate, products of soaking row tea, free amino acids increased.

结果表明，恒温恒风调控方式能有效降低叶层空气的相对湿度，改善空气质量，增大青叶的气孔导度、失水速率及呼吸速率，提高毛茶的水浸出物和游离氨基酸含量，毛茶品质较优。

The density of stoma in the down-epidermis was bigger than the up-epidermis, the two sides of the leaf had corneous layer.

叶为异面叶，表皮毛为多细胞型，下表皮气孔密度多于上表皮，上下表皮均有角质层。

The stoma morphology, leaf development characteristics and leaf water-holding ability of Cylocarya paliurus seedlings from three provenances were investigated after salt treatments.
