摘　　要：比较了不同消毒方法处理后膏桐种子的霉烂率和发芽率。结果表明,与对照相比,不同浓度高锰酸钾溶液浸种30min,虽然可显著降低霉烂率,但同时也抑制了发芽率;1%硫酸铜溶液浸泡10、20和30min处理,不仅显著降低霉烂率,而且明显提高种子的发芽率,其中,1%硫酸铜溶液浸泡种子30min效果最好;而高锰酸钾不适于膏桐种子的消毒处理。The statistics of decayed seeds and testing of seed germination in Jatropha curcas were conducted after sterilization with different treatments. The results indicated that there were significant differences in disinfection effect and seed germination rate of the seeds soaking with different KMnO4 concentrations for 30 min and soaking with 1% CuSO4 for 10 min, 20 min and 30 min, respectively. Among these treatments, soaking seed with 1% CuSO4 for 30 min was the best, which not only presented the best disinfection effect, but also could break the dormancy and accelerate the seed germination of Jatropha curcas. The germination of Jatropha curcas seed was inhibited after KMnO4 treatment.
