Research Progress on Dormancy of Paeonia suffruticosa

Paeonia suffruticosa is a unique ornamental, medicinal and oil plant in China.Its seeds、buds and test tube plantlet have dormancy characteristics, which seriously restricts the industrialization development of peony.In recent years, the research on dormancy of Paeonia suffruticosa mainly focused on the mechanism of seed and bud dormancy and the method of breaking dormancy, but the research on test-tube seedling, dormancy was still in the primary stage.In this study, the recent advances in Paeonia suffruticosa dormancy were reviewed, and the reasons mechanism and methods of breaking dormancy of Paeonia suffruticosa seeds and buds were summarized.And the problem in this research were also discussed.In the later stage, we should study the dormancy mechanism of seed and bud, on the other hand, we should study the dormancy of tissue culture seedlings of Paeonia suffruticosa,to provide theoretical basis and technical support for the method of breaking dormancy of Paeonia suffruticosa.
