摘　　要：对苦参种子硬实的最佳破除方法、最适发芽的温度、光照条件及盐浓度对种子萌发的影响进行了研究。结果表明:98%浓硫酸处理、烫种和砂纸磋磨处理均可提高苦参种子的发芽率,其中以98%浓硫酸处理40 min为最佳处理方法;25℃为苦参种子发芽的最适温度,光照条件非苦参种子萌发的必备条件;适量的NaCl(<5 g/L)有利于提高苦参种子的发芽势和发芽率,高浓度的NaCl(>7 g/L)则明显抑制种子萌发。Seed treatment methods,temperature,illumination and salt concentrations on the seed germination and seedling growth of Sophora flavescens Ait were studied.The results indicated that the seed treated with 98% H2SO4,scalding with boiling water and grinding with sand paper could improve germination rate obviously,and the effect was the best when treated with 98% H2SO4 for 40 minutes.For the seeds of Sophora flavescens Ait,the optimum temperature was 25℃,illumination was not essential to Sophora flavescens Ait seed germination.And the germination potential as well as germination rate under low NaCl concentrations（0.5%） was higher than that of high NaCl concentration,and high NaCl concentrations（0.7%） obviously inhibited seed germination.
