Figure 7.
Effects of 150 mM NaCl on sodium and potassium contents in wild and cultivated rice seedlings after 14 days of stress. (A) Sodium content in shoots (B) Sodium content in roots. (C) Potassium content in shoots (D) Potassium content in roots. Data represent the means ± SE (n = 9). Asterisks indicate the significant difference of salt-stressed plants with respect to non-stressed plants, based on the Student t-test (ns-not significant, * p ≤ 0.05). DW—dry weight.
