Effect of ouabain on stomatal movements and transpiration rate of Secale cereale

Abstract

Young rye seedlings (Secale cereale cv. Petkus) were grown for 12 or 18 din aerated nutrient solution. CO2-free air in light or in darkness induced stomatal opening. When light and CO2-free air were applied together, maximum stomatal opening was observed. Na+ channel inhibitor [3H]ouabain was taken up from nutrient medium and translocated into the leaves… (More)
