Abstract Responses of stomata to light and CO2 were smaller when detached epidermis of Commelina communis L. was incubated on a medium containing 50 mol m−3 NaCl than when an equimolar KCl solution was used. Although opening in the light in the absence of CO2 seemed to be the same whichever salt was present, apertures on KCl solutions were smaller in the dark or with CO2-containing air. The response to 10−7 mol dm−3 ABA was similarly reduced in the presence of NaCl. If there is an optimal NaCl concentration for stomatal CO2 and light responses it is at or below 25 mol m−3. These findings point towards control of stomatal movements by light, CO2 and ABA at the level of cation uptake or extrusion.
