Investigation on cultivation and application of tree peony in Zhejiang and Anhui.

On-the-spot investigation and analysis of cultivars,plant area,management and application of tree peony were conducted in the south of Anhui and Zhejiang in order to provide the basic information and reference for the construction and development of peony industry. The survey recorded 16 traditionalcultivars,of which 10 cultivars were recorded in book of Chinese Tree Peony(Volume of Northwest,Southwest,and South of the Yangtze River),6 were the new records; 9 new cultivars were breeds of Fengdan strain. Under natural conditions the growth of traditional cultivars was better than that of introduced cultivars. The adaptability of introduced cultivars was significantly different and the selection of introduced cultivars should be paid attention to. The main application of tree peony in Zhejiang and Anhui was the species-divided gar-den. But the ways of development were diversified. To develop tree peony in the south of the Yangtze River,it's necessary to establish a resource base for tree peony cultivars,hence the peony resources collection,standard nomination of cultivars,introduction and cultivation of new cultivars can be carried out in a planned way.
