In this article:
Stomatal closure associated with plant moisture stress probably depends upon the combined effects of reduced turgor and abscisic acid (ABA) formation within the leaves.
Vine leaves were excised to follow any short term increase in ABA-like inhibitors at the onset of stomatal closure and then relate this information to changes in leaf water potential, any gas exchange during prolonged moisture stress and subsequent recovery.
The results emphasise the speed with which levels of endogenous ABA-like inhibitors can alter in response to changes in leaf water potential.
