Abstract
25 provenience of Quercus variabilis seeds were collected from its main distribution area in China.Raising seedlings experiments were carried out at Caichong Village,Huanggang Town,Feixi County,Anhui Province.Seedling growth traits and biomass were measured.The results showed that Q.variabilis seedling height and ground diameter growth showed an S curve,with July to September as the fast-growing period.Significant differences were observed on height,ground diameter,height to diameter ratio,biomass and roots from different Q.variabilis provenience.Height was significantly positive related to ground diameter,stems,leaves,total biomass.Significant positive correlation was also observed between ground diameter and root,stem,leaves,the total biomass.Similarly,roots were significantly positive correlated with the stem,leaves,biomass too.Principal component analysis showed that the main differences among provenience were decided by the ground diameter and biomass of various parts of the plant.Seven improved provenience,originated from Menghai of Yunan Province,Dongzhi of Anhui Province,Xingyang of Henan Province,Youyang of Chongqin city,Hangzhou of Zhejiang Province,No.2 Jinzhai of Anhui Province and Jixi of Anhui Province,were selected.
