| Abstract: | Paeonia ostii ‘Feng Dan’ is rare and valuable treasure of peonies, its medicinal value ranks the top among the four famous Chinese medicine.However, the cultivation of P.ostii ‘Feng Dan’ has been limited due to high level of seed dormancy.In the study, the effects of different treatments (AgNO3, GA3, KT, TDZ and 4℃) on seed dominancy were studied.The results showed that the treatments of AgNO3, GA3 and 4℃ accelerated germination, produced high germination rate and improved the growth (fresh weight, seedling length and root development etc.) of P.ostii ‘Feng Dan’ seedling compared with the control to some extent. |
