Abstract
Boron enhances stomalal opening in epidermal strips of Commelina communis L. under conditions conductive to opening, i.e. light and KCI. This effect is obtained when boron is given together or before KCI application. Since boron increases 86Rb net uptake in both illuminated epidermal strips and illuminated isolated guard cells, it is suggested that boron acts either by reducing potassium leakage or by increasing its uptake, thus leading to increased osmotic potential and, as a result, to stomatal opening.
