【摘要】 调查了4个试验点5年生白桦种源试验林的树高、地径、保存率,采用方差分析及多点种源试验联合分析方法。进行差异显著性分析。结果表明:各试验点不同种源间生长量、保存率等性状差异明显,种源与立地的交互作用尚未达到显著水平。利用各种源的生长量、保存率等性状与各种源的地理气候因子进行相关分析,同时以树高、地径、经纬度为变量进行回归分析,研究种源的地理变异规律。由于各种源的适应性不同,造成各试验点的种源地理变异规律不同。利用聚类分析进行种源区划、初步化分为12个种源区。最后综合各种源的生长量和适应性,为4个试验点初步选择出各自的最佳种源。

【Abstract】 Based on the 5 years tree height. diameter breast-high (DBH). survival rate of 4 experimentalplaces. through variance analysis and combined analysis among provenances, the significant differenceswere made. The results indicate that there exists significantly difference between different provenances inthe growth volume. survival rate and so on characters. The interaction between provenances andpositions was weak. The correlation analysis between the growth productivity. survival rate and climaticfactors. the regression analysis among the tree height. DBH, longitude and latitude were used to investigatethe geographic variance rule. It manifests that the geographic variance rules are different according to thedifferent adaptabilities of provenances. By the clustering analysis. it is divided into 12 provenance positions.So the optimal provenances for 4 experimental places were selected by the growth productivities andadaptabilities of provenances.
