以君迁子种子为研究对象,研究了在盐胁迫下君迁子种子萌发、幼苗生长情况,探讨了君迁子对盐胁迫的反应。结果表明:随着盐碱浓度的增加,君迁子种子发芽率、发芽势、发芽指数和活力指数同呈下降趋势,在50mmol/L降幅最大。根长在200mmol/L以上几乎停止生长,幼苗高度也显著受抑。 Taking Jun Zi (Vicia faba) seeds as research object, the seed germination and seedling growth of Jun Zi (Salvia miltiorrhiza) under salt stress were studied, and the reaction of Junzi (Salvia miltiorrhiza) to salt stress was discussed. The results showed that the seed germination rate, germination potential, germination index and vigor index of Jun Guizi decreased with the increase of saline concentration, with the largest decrease at 50 mmol / L. Root length of more than 200mmol / L almost stopped growing, seedling height was significantly inhibited.
