To reveal the difference of Paeonia lactiflora growth between direct introduction(T1)and restrain transplanting 3 years after introduction(T2),an experiment was carried out to explore the suitability of foreign P.lactiflora in China suitability period.Agronomic traits,quality seeding and content were measured regularly.The results showed that the climatic condition in Yongdeng County was suitable for cultivating P.lactiflora.Foreign P.lactiflora could grow and blossom,meanwhile pure colour,full flower shapes,upright and strong stems,and rich leaves were obtained under the field management conditions both in T1 and T2.Compared with T2,T1 showed better growth performance,survival rate was increased by 4.26%(P<0.05),survival rate of the flowering rate was increased significantly by 8.34%(P<0.01),fresh weight of root seedling,root diameter,root length,lateral-roots and the number of buds were increased by 0.31 kg(P<0.05),3.27 mm(P<0.05),7.00 cm(P<0.05)and 5 numbers(P<0.01),the content of its main component paeoniflorin was increased by 48.68%(P<0.01).In conclusion,the direct introduction is more conducive to the growth of P.lactiflora and has higher market prospect and value.
