A large amount of research results showed that plants show isohydric behavior when the plant hydraulic and chemical signals cooperate to promote the stomatal regulation of leaf water potential.

当植物力信号和化学信号共同作用促进气孔对叶调节时，植物对叶调节表现等行。

Antitranspirant A chemical that reduces transpiration. Antitranspirants may work by depositing a waterproof film over the stomata or by inducing stomatal closure.

可减少蒸腾作用化学物质。抗蒸腾剂可沉积气孔上防膜或诱导气孔关闭起作用。
