To improve the cultivation of current peony ,use and protect wild peony resource ,we did a research on the peony in China .There has seven species ,one variety and one supspecie in all of China .From literature ,wild investigation and so on ,we concluded three characteristics .Firstly ,peony and pobovata was distributed in most of china ,peony cut flower and peony cut flowers was distributed in Tibet ,and others were distributed in the central or west south of China .Secondly , as a result of XingJiang peony and beautiful peony’s beauty ,they can be used in cultivation and most of them are sciophile .At last ,the hybridization between wild and cultivated specieses can form macroprogeny .Apart from that ,we know that the wild peony resourses are pessimistic ,which caused from the destructive lumbering and the excellent resistance disease and negative in wild peony can offer a material basis for species improvement . |
