摘　　要：对绞股蓝(Gynostemmapentaphyllum(Thunb)Makino)的种子在不同温度、不同时间下进行浸种处理,根据其种子的发芽率、发芽势以及幼苗生长情况分析得出:浸种时间以16h处理的发芽率、发芽势较高;浸种温度以20℃的处理为宜;黑暗条件下的浸种处理,其发芽率、发芽势及幼苗生长状况均高于光照条件下;用0.1mg/L的GA、6-BA浸泡后,发芽势和发芽率显著提高,但对幼苗生长有仰制作用.Seeds of Gynostemma pentaphyllum were treated at different dipping times and temperatures,their germinating energy, germination vigor,seedling growth were tested. The results were as follows： 1.the best dipping time and temperature are 16 hours and 20℃ respectively;2. The seeds treated in the dark have higher germinating energy and germination vigor than those treated in the light; 3. Their germinating energy and germination vigor are obviously increased, but seedling growth is decreased when the seeds are treated with 6-BA and GA.
