Fig. 2From: Residual transpiration as a component of salinity stress tolerance mechanism: a case study for barley a genetic variability in osmolality of barley leaves at three positions in plants grown under normal (no salt) growth condition. Mean ± SE (n = 6). b correlations (Pearson’s R2 values) between leaf sap osmolality 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 < 0.01Back to article page
