Effects of different salt treatments on ion contents of <i>Elaeagnus angustifolia</i> seedlings.

<p>Na⁺ (A), Cl^- (B), Ca²⁺ (C), Mg²⁺ (D), K⁺ (E) concentrations and K⁺/Na⁺ ratios (F) were determined in roots, stems and leaves of <i>E</i>. <i>angustifolia</i> seedlings hydroponically treated with 0, 100 and 200 mM NaCl for 30 days. Each vertical bar represents standard error (SE) for the mean (M) of three replications (n = 3). Different letters above the vertical bars denote the significant levels at 0.05 according to Duncan’s multiple-range test (A-C denote significance between the different plant organs at a given salt concentration, whereas a-c denote significance between the different salt concentrations in a given plant organ).
