1.There are a few stomatal apparatus in abaxial . The surface of guard cells and accessory cells are smooth.
气孔器仅见于下表皮，分布稀疏，副卫细胞和保卫细胞表面光滑。
2.At the early stages, the cell initiation was finished, so stomatal density decreased gradually due to the expanding cell mentioned above.
在发育早期，细胞的分裂已完成，因此气孔密度因表皮细胞体积的增大而不断减小。
3.Stomatal apparatus are often distributed in lower epidermis. Epidermis cells is of different shape in different plants.
气孔器常分布下表皮，在不同植物中表皮细胞有不同的形状。
4.The number of chloroplast and chlorophyll content in the dodecaploid are more than hexaploid, stomatal density are lower than hexaploid.
同时，十二倍体较六倍体的叶绿体数目明显增多，叶绿素含量提高，但气孔密度减小。
5.Stomatal distribution, morphology and behavior respond to a spectrum of signals, from intracellular signaling to global climate changes.
气孔的形态、发育和开闭行为受到从细胞到全球尺度的信号调控。
6.Water metabolism is an important part of plant metabolism. Stomatal opening and closing modulate water loss and photosynthesis.
水分代谢是植物基础代谢的重要组成部分，气孔开关精细地调节着植物水分散失和光合作用。
7.Phyllostachys pubescens; net photosynthetic rate; transpiration rate; stomatal conductance.
孟宗竹；净光合作用速率；蒸散速率；气孔导度。
8.Under full irrigation condition, stomata open completely, and stomatal resistance and canopy-air temperature difference are smaller.
水分充足时，气孔处于全开放状态，气孔阻力较小，冠气温差较小；
9.The stomatal indexes and the stomatal density are various among the different plant groups.
气孔指数和气孔密度不同植物间变化较大；
10.Stomatal, dispersed shrinkage, shrinkage cavity, sonim and slag inclusion belong to this kind of defect.
属于这种类型的缺陷有气孔、缩松、缩孔、夹砂、夹渣等。
