OBJECTIVE： To select the optimum conditions for germination test of Sophora alopecuroides seed， and to provide reference for formulating seed test rule and standardization of S. alopecuroides. METHODS： S. alopecuroides seeds were soaked in 98％ H2SO4 for 30 min and 35 ℃ warm water for 29 h， and then treated under different temperature conditions （15 ℃， 20 ℃， 25 ℃ and 30 ℃）， different germination beds （on paper， between paper， on sand， in sand） and different light conditions （2 000 lx lighting 16 h， dark）. Optimal germination condition was screened by using germination rate， germinative potential and germinative index as indicators. S. alopecuroides seeds were cultured under this condition for 7 days， and then germination rate was determined. RESULTS： Different temperatures had no significant effect on germination rate， but influenced germinative potential and germinative index； those indicators reached maximal value at 20 ℃. Different germination beds affected each indicator， and under condition of on sand， those indicators were the highest. Light treatment had no significant effect on germination indicators. Under suitable condition， the seed sprouted since first day of germination bed treatment； germination rate was more than 90％ on second day， and reached maximal value on fifth day and didn’t increase any longer. CONCLUSIONS： The suitable condition of seed germination was soaking in 98％ H2SO4 30 min+35 ℃ warm water for 29 h， on sand under light at 20 ℃. Initial count on second day of germination bed treatment and final count on forth day were analyzed statistically as well as germination rate. This method can be used as standard quality test of the seed of S. alopecuroides.
