Table 2.
Total “osmotic pool” was estimated by dividing the amount of all analyzed solutes (Na+, K+, amino acids and proline) by the amount of water in the leaf tissue: the contribution of each solute was expressed as a percentage of the total “osmotic pool”. The values are means of three replicates
