摘　　要：[ Objective] To study the germination characteristics of Hordeum brevisubulatum seeds in the Songnen Plains of China under different conditions and find out the optimum conditions for germination. [ Method] A total of five variable temperatures including 15/25, 20/30, 15/30, 20/25 and 15/20 ℃, five concentrations of sodium chloride solutions including 0, 75, 85, 95 and 105 mmol/L, and five concentrations of CS2 strain （the A values were 0, 0.500 0, 0.050 0, 0.005 0 and 0.000 5, respectively） were studied by orthogonal experimental design. [ Result] The germination rate, germination energy and germination index were significantly （ P 〈 0.05） affected by the temperature and sodium chloride concentration, but rarely affected by the CS2 strain concentration. Moreover, the germination rate, germination potential and germination index were all decreased with the increasing of sodium chloride concentration. [ Conclusion] The optimal germination conditions of Hordeum brevisubulatum are as follows： temperatures of 15/25 ℃ and 15/30℃, 0 mmoVL of sodium chloride concentration.[ Objective] To study the germination characteristics of Hordeum brevisubulatum seeds in the Songnen Plains of China under different conditions and find out the optimum conditions for germination.
