摘要：1996年从我国樟树全分布区采集50个樟树种源种子,1997年在浙江省余杭市长乐林场进行苗期试验。对1年生樟树苗生物量及相关性状进行调查观测,通过方差分析、相关分析等方法,分析樟树苗期生物量及组成生物量相关性状的种源间差异、苗期生物量与种源产地气候关系以及各性状间的相互关系。结果表明,苗期生物量种源间差异显著;包括苗高和地径在内的各性状之间存在着显著的表型和遗传相关;与苗期单株生物量相关最为紧密的性状是地径(rP=0.847,rG=0.802)。通过无约束指数选择法,评定了各种源的综合表现,并选出广东连州、江西井冈山、福建建瓯、浙江庆元、福建上杭5个苗期表现优良的种源。
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.
