Accumulation of Na+ and K+ in leaves of salt-treated chickpea plants. (a) Based on sap, or leaf water content, (b) based on leaf dry weight, and (c) the ratio of Na+/K+ calculated from the same samples. Significant differences are indicated by different letters (p < 0.05), calculated using ANOVA with post-hoc Tukey tests (n = 8 ± S.E.M.)
