Epidermal strips from well-watered faba-bean plants were subjected to a range of abscisic acid (ABA) and indolyl-3-acetic acid (IAA) concentrations (10-5 to 1 mM) in the presence or absence of CO2 in light or dark. ABA had inhibitory effect on abaxial stomatal apertures in all the concentrations studied and retained them closed even after addition of KCl (SO and 100 mM) to the incubation medium. It also influenced stomatal responses to CO2. In the presence of CO2 apertures were greater than in… CONTINUE READING
