Table 1. Changes in shoot height, shoot fresh and dry weight of wild sand cultivated soybeans under control and salt stress conditions.

The values are shown as mean ± SE. Different letters (A–G and a–g) mark significantly different values at P < 0.05 according to Duncan’s method. W, wild soybean; C, cultivated soybean; CK, Control; L-NS, M-NS, and H-NS represent low (10 mmol L ), medium(20 mmol L⁻¹) and high (30 mmol L⁻¹) concentrations of saline salt stress, respectively; while L-AS, M-AS and H-AS represent low (10 mmol L⁻¹), medium (20 mmol L⁻¹) and high (30 mmol L⁻¹) concentrations of alkaline salt stress, respectively.
