    • Abstract

       

      The apertures of stomata on isolated epidermal peels from both the leaf surfaces ofCommelina communis were reduced in response to chlorocholine chloride as the concentrations increased from 0·01–10·0 mol m−3. When chlorocholine chloride was applied in combination with different concentrations of indoleacetic acid, stomatal closure occurred only when a high concentration of chlorocholine chloride was applied with a low concentration of indoleacetic acid, while low concentrations of chlorocholine chloride did not affect the stimulation of aperture caused by indoleacetic acid treatments. Chlorocholine chloride treatments caused depletion of K+ from the guard cells while indoleacetic acid resulted in accumulation of K+.
