Abstract

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.
