Effects of salinity and leaf age on the FV channel activity in quinoa mesophyll vacuoles. A and B, Whole vacuolar FV conductance versus voltage, the first derivative of the whole-vacuole I/V relation, measured upon establishment of the high-conductance state. C, Same data as in A and B, but only the points within the physiological tonoplast potential range (±20 mV) are considered. Data with different lowercase letters are significantly different at P < 0.05. O, Old leaves; Y, young leaves. Data are means ± se (n = 3–7 vacuoles for each condition). Other conditions are as in Figure 8.
