Study on the Biomass Variance and Comprehensive Evaluation at the Seedling Stage of Cinnamomum comphora Provenances

The provenance test at seedling stage was carried out at the nursery of Changle Forestry Farm in Yuhang City,Zhejiang Province in 1997 with the 50 provenance seeds collected from the distribution area fo C.comphora(L.) Presl in 1996.Seedling biomass and relative traits were observed and the relationship among traits was analyzed with variance analysis,relationship analysis and comprehensive index selection.The results show that there is extreme significant difference on the seedling biomass among provenances and extreme significant relationship among 9 traits including seedling height and seedling ground diameter,in which the ground diameter is a leading factor related to the seedling total biomass.Also,five superior provenances were selected with the comprehensive index selection,they are Lianzhou (Guangdong),Jinganshan(Jiangxi),Jianou(Fujian),Qingyuan(Zhejiang)and Shanhang (Fujian) provenances.
