摘要(Abstract)：

对我国15个枫香地理种源的4.5 a生幼林树高、胸径和冠幅等生长性状进行测定。通过方差分析、相关分析和遗传力参数等的估算结果表明:各地理种源间树高、胸径和冠幅差异极为显著,且树高和胸径有较高的广义遗传力,受中等强度遗传控制。树高、胸径与各种源的地理位置不相关,冠幅与纬度呈显著正相关。采用聚类分析,可以划分为4个种源区。根据枫香幼林生长表现,南部种源区表现最差,以中部种源区的湖南桑梓和东部种源区的江西湖城表现最好。
The measurement was made of he growth traits of 4.5-year old young forest from 15 Liquidambar formosana geographic provenances, such as tree height, diameter at breast height(DBH), and crown breadth. The resuts of their variance and correlation analysis and genetic parameter estimation showed that there were significant differences among tree height,DBH and crown breadth among different Liquidambar formosana provenances. And the broad heritability of tree height and DBH were high,and was controlled by moderate genetic strength. There was an uncorrelated relation between tree height and DBH, but the crown breadth had a significant positive correlation with the latitude. The provenances could be divided into 4 provenance zones by using cluster analysis. As for the growth expression of young forest of Liquidambar formosana,the performance of the south provenance was worst,the performances of Sangzi town in middle provenance zone and Hucheng county in east provenance zone were best.
