Abstract
The germination rate was determined for Leymus chinensis seeds under NaCl, Na_2CO_3, and mixed salt stress. The germination rate was higher than the control for NaCl concentration of 12.5～600 mmol/L, Na_2CO_3 at 12.5～150 mmol/L and mixed salt at 37.5～250 mmol/L. Germination rate was highest when NaCl and Na_2CO_3 had a concentration of 12.5 mmol/L, and mixed salt had a concentration of 75 mmol/L. Germination rate was higher under NaCl stress than under Na_2CO_3 and mixed salt stress. It was shown that appropriate concentrations of salt-alkali can promote seed germination, and that neutral salt was the most suitable to promote seed germination. ANOVA analysis showed that the germination response of Leymus chinensis seeds under the three kinds of salt-alkali stress showed differentiation. The CV of germination rate was 64.1905%～66.6255%. Under different environmental conditions, Leymus chinensis seeds have ecological plasticity.
