Abstracts:Ten provenances of Liquidambar formosana were collected from different regions and provinces and planted in Jiufeng Experimental Forest Farm of Hubei province.The indexes including tree height,diameter at breast height,and volume and phenology rhythm of 6 year old young Forest were investigated.The results showed that the growth traits for tree height,diameter and volume among different provenances were extremely significant differences,and pairwise index showed a significant positive correlation. Provenances of‘Jiangsu Nanjing’and‘Henan Shangcheng’were advantage for growing in it.However, provenances of‘Henan Nanyang’and‘Henan Shangcheng’were worst growth condition.Tree height showed a significant positive correlation with latitude and annual rainfall, respectively,and diameter at breast height and volume was a significant positive correlation with annual rainfall.Budding period, magenta leaf stage,leaf expansion period and defoliation period of different provenance were significant differences,and budding period, magenta leaf stage, primary leaf expansion period, exuberant leaf expansion period and primary defoliation period of‘Guangxi Cenxi’and‘Yunnan Funing ’in low latitude advanced more than that of high latitude, while exuberant defoliation period and telophase defoliation period were lagging behind.
