Vacuolar pH Variability in a Protoplast Population
Different methods to determine the vacuolar pH have been proposed (see Kurkdjian et al. 1984 for a review). Techniques used for plant organs or cells are not always suitable for protoplasts or isolated vacuoles. Furthermore, most of them consider a cell population as a whole (plant organ or suspension of cells in liquid medium) and give a “mean” pH value which in turn depends on the technique used to obtain it (Kurkdjian et al. 1984c).
