Abstract: Salt stress is one of the main abiotic stresses affecting plant growth at present.In this study, the NaCl solution with different concentrations were used to stress Sophora alopecuroides and soybean W 82 at the seed germination stage and seedling stage, respectively.The germination rate and germination potential of S. alopecuroides and soybean W 82 under different concentrations of salt stress were calculated, and the phenotypic changes of seedlings were also observed.Meanwhile, the activities of antioxidant enzymes（POD,CAT,SOD） in the radicle after treatment were determined, and the salt tolerance of S. alopecuroides and soybean during germination stage and the difference between them were analyzed.The results showed that the germination rate of S. alopecuroides decreased by 29.09%,germination rate of soybean W 82 decreased by 77.5%,germination potential of S. alopecuroides decreased by 53.97%,and germination potential of soybean W 82 decreased by 95% at 1.2% concentration.The salt tolerance of S. alopecuroides was stronger than that of soybean W 82 at the germination stage.The wilting concentration of S. alopecuroides seedlings was 1.2%,and that of soybean W 82 seedlings was 0.9%.Phenotypic analysis showed that the salt tolerance of S. alopecuroides seedlings was stronger than that of soybean W 82 at bud stage.
