Abstract

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.

Key words： Jatropha curcas; seed; disinfection method; compare
