Abstract:
Objective: To study the rule of breaking seed dormancy and content changes of endogenous hormone of the Paris polyphylla var. Yunnanensis seeds. Methods: The seeds were treated under fluctuating temperature, and the content of endo-hormone, such as GA, IAA, and ABA, was mensurated by HPLC. Results: During the first three months, the stratification under fluctuating temperature could break the seed dormancy. The content of GA rose obviously and the content of ABA reduced. Conclusion: It is suggested that ABA and GA have significant effect on the dormancy and germination of P. polyphylla var. yunnanensis seeds.
