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

可以减少蒸腾的质。抗蒸腾剂可以通过沉积气上的防水膜或诱导气关闭。

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处理对两种苗木叶水势下降抑制最小，F5处理对两种幼苗叶水势的下降抑制最大。
