Among the five antitranspirants, antitranspirant F1 had the least inhibition effect while antitranspirant F5 had the greatest inhibition effect on the decrease of leaf water potential.

F1两种苗木叶水势下降抑制作用最，F5两种幼苗叶水势的下降抑制作用最大。

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.
