Abstract

The vacuolar pH of individual cells of the epidermis of intact leaves of Commelina communis L. has been determined using pH sensitive microelectrodes. The results show that the pH of the guard cells increases by approximately 0.5 units during stomatal opening. The changes in vacuolar pH mirror the changes in vacuolar potassium concentration that occur during stomatal movements.

摘要

使用 pH 敏感微电极测定了完整的鸭跖草属植物叶片表皮细胞的液泡 pH 值。结果表明，气孔开放时保卫细胞的 pH 值大约增加 0.5 个单位。液泡 pH 值的变化反映了气孔运动过程中液泡钾浓度的变化。
