1·Conversely, when atmospheric carbon dioxide is low, stomatal density tends to increase - it's like getting more mouths to breathe with.
相反，当大气二氧化碳浓度低时，气孔密度似乎增加了——就像长出更多的嘴来呼吸。
2·The pattern made by the cells of a leaf’s stomatal openings can help paleobotanists to identify it.
叶子气孔细胞的这种活动方式有助于古植物学家识别它。
3·Our results showed that young grape plants were able to adapt to a low light environment, and their leaf transpiration characteristics were correlated with stomatal structure.
说明葡萄幼苗能够对弱光环境产生适应性变化，其蒸腾特性的变化与其气孔结构的变化相关，具有一致性。
4·The results showed that stomatal density of flag leaves has significant difference among types and varieties, which is a character of variety.
研究结果发现，剑叶的气孔密度在水稻类型间和品种间具有明显差异，是一个品种特性。
5·This phenomenon is mainly caused by the stomatal resistance.
这种现象是由于受气孔阻力的影响所致。
