Effect of Varied Treatments on Germination of Polygonatum cyrtonema Hua Seeds

Effect of storage conditions and methods of breaking dormancy for the germination of Polygonatum cyrtonema Hua seeds was investigated in preparation for its cultivation.The wild seeds were stored under varied conditions.Physical and chemical methods were applied to break the seed dormancy.The results showed that the seed germination rates under the sand storage at normal and low temperature were not significantly different.However,the rate was markedly decreased when the seeds were stored at ambient temperature in dry storage.No significant difference on the germination rate was found when the seeds were treated with different physical and chemical means.The highest germination rate,93.33%,was obtained by soaking the seeds in 50 mg·L-1 GA3 solution for 3hours at low temperatures.
