Abstract
Closure of stomata caused by low (10(-7)M) concentrations of abscisic acid (ABA) is specific for cis-trans ABA, and is initiated within 5 minutes. Upon withdrawal of the hormone supply, reopening starts within 5 minutes. Gas analysis of leaves treated with ABA or DCMU allows one to distinguish effects on the stomatal apparatus from inhibition of photosynthesis and to conclude that ABA acts on stomata directly.
摘要
低浓度（10（-7）M）脱落酸（ABA）引起的气孔关闭是 cis-trans ABA 特有的，并且在 5 分钟内开始。当激素供应停止时，在 5 分钟内开始重新打开。用 ABA 或 DCMU 处理的叶片的气体分析允许人们将气孔装置的作用与光合作用的抑制区分开来，并得出 ABA 直接作用于气孔的结论。
