Abstract:
Objective: To explore the impacts of temperature, endogenous hormone, and pollination methods on the seeds germination and emergence of Paris polyphylla var. yunnanensis and polygerm varieties, and establish the technical system to promote the germination of P. polyphylla var. yunnanensis seeds and provide scientific guidance for the cultivation of Paris L., To ease the bottleneck problem of current serious shortage of high quality source of seeding material and commercial herbal products of Paris L., and highest market price. Methods: Using wet sand cultured P. polyphylla var. yunnanensis seeds under different conditions and determined the rate of germination and the mean germination time, the cultivated seeds were planted in the field to investigate the rate of seedling emergence and the average time of emergence. Results: The higher germination rate and emergence rate were obtained at the temperature of 4-18℃; Gibberellin (GA3) treatment could promote the seed germination, and reduce the mean germination time, especially in 100 and 200 mg/L; The germination rate and emergence rate of artificial pollination were significantly higher than natural pollination (P < 0.05); There is no difference between P. polyphylla var. yunnanensis and polygerm varieties seeds. Conclusion: The peeled seeds are treated by 100 mg/L gibberellin, and cultured to sprout by wet sand at the temperature of 4-18℃, then sown in the field. It can shorten the seed emergence period one year and up to more than 80% of emergence rate.
