Popis:	One of the most clearly defined roles for abscisic acid (ABA) is the induction of stomatal closure when water supply is suboptimal (Mansfield & Davies, 1981). Ca2+ is also known to induce stomatal closure but its role as a regulator of guard cell turgor has received little attention. As Elliot and coworkers (1983) reported that calmodulin (CaM) antagonists influence growth regulator action it seemed logical to investigate whether Ca2+ and ABA interacted in influencing stomatal aperture.
