Stomata in isolated epidermal strips open in response to light plus air free of carbon dioxide when the strips are floated on potassium chloride solutions of low concentrations. This opening depends on the stimulation of active accumulation of potassium in quantities sufficient to account for the observed changes in solute potential of the guard cells.
当分离的表皮条漂浮在低浓度氯化钾溶液上时,其气孔会在光照和无二氧化碳的空气中开放。这种开放取决于钾离子的主动积累受到刺激,积累的钾离子数量足以解释观察到的保卫细胞溶质势的变化。
