摘　　要：对桃叶卫矛种子的发芽特性进行了研究 .结果表明 :采种时间晚 ,有利于提高桃叶卫矛种子的播种品质 ;人工母树种子的抑制物质存在于假种皮中 ,去除假种皮进行高温催芽 ,种子可快速发芽 ;天然母树种子的抑制物质不仅存在于假种皮中 ,而且存在于种子内部 。The germination characteristic of Euonymus bungeanus seeds was studied in this paper. The results showed that the later picking was propitious to improve the seeding quality of Euonymus bungeanus seeds. The inhibitory substance of artificial maternal plant was existed in bogus seed capsule. If we got rid of the bogus seed capsule and accelerate the germination of seeds in high temperature, the seeds would germinate quickly. The inhibitory substance of natural maternal plant was not only in bogus seed capsule but also in inside of seeds. The accelerating the germination of seeds in low temperature could break the dormancy of seeds.
