摘　　要：以采自云南双柏县的膏桐种子为试材,测定种子千粒质量、出仁率、种仁千粒质量、种仁含油率、种子含水量、自然虫蛀率、不同处理和不同贮藏温度下发芽率和发芽势等指标。结果显示,双柏县膏桐种子千粒质量为556.25 g,出仁率为75.09%,种仁千粒质量为382.53 g,种仁含油率为55.90%,种子含水量为5.98%,自然虫蛀率为24.91%,不同处理和贮藏温度对种子萌发影响不显著。The indexes of Jatropha curcas seeds collected from Shuangbo County, Yunnan Province were meas- ured including 1 000-seed weight, kernel weight of seed, 1 000-kernel weight, kernel oil content, moisture content, natural vermiculated rate, germination rate and germination energy of the seeds treated by different storage methods and different storage temperatures. The results showed that the 1 O00-seed weight was 556. 25 g, kernel weight of seed was 75.09%, 1 000-kernel weight was 382.53 g, kernel oil content was 55.90%, seed moisture content was 5.98%, and the natural vermiculated rate was 24.91%. The study showed that the seed germination rate and germination energy indexes were not significantly influenced by different storage treatments and different storage temperatures.
