摘　　要：采用室内试验测试和统计分析方法,研究了桃叶卫矛种子的休眠机制,并探讨种子的催芽方法。结果表明:桃叶卫矛种子休眠属于形态生理休眠。针对该休眠类型催芽试验采用了赤霉素和层积处理相结合的方法来打破休眠,最终确定发芽效果最好的方法为:300mg/L赤霉素处理48h后,将种子置于25℃环境条件下层积28d,种子发芽率在10d内达到95%以上。In this paper, we studied the dormancy mechanism and germination method of Euonymus bungeanus seeds.The result indicated that the dormancy type of E.bungeanus seeds belonged to Mor- phophysiological dormancy.We used the method of GA3 with stratification to break the dormancy for this type dormancy.At last,we selected the best way to break the dormancy which is the combination of 300 mg/L GAs after 48 hours processed with 25 ℃ stratification for 28 days,the germination rate can be reached to 95% for 10 days.
