Fig. 3
a genetic variability in osmotic potential of barley leaves at three positions in plants grown under normal (no salt) condition. Mean ± SE (n = 6). b correlations (Pearson’s R2 values) between leaf osmotic potential and residual transpiration measured by two different methods. Data labelled with different lower case letters are significantly different at P < 0.05 and asterisks are significant at P < 0.01
