Abstract: A provenance trial of Cunninghamia lanceolata Hook. at Fujian was analysed for growth, wood quality and branch traits. Highly significant differences were obtained for all the seven traits among the 81 provenances tested. All provenances were divided into eight groups with different characters according to the results of principal components analysis and cluster analysis.The results of canonical correlation analysis show that there exists significant correlation between the biological trails and geographical coordinates (longitude,and latitude), and significant geographical variation trends were obtained for traits. By correlation analysis and trend surface analysis, it was found that growth traits were signifcant negatively correlated with latitude, but not significant with longitude. There may be a tendency that specific gravity decreased from east to west. Taking the region 106~ 112 degrees longitude and 25~28 degrees north latitude as center, the values of branch traits declined with increasing or decreasing longitude and increased with increasing or decreasing latitude. The crown of the provenances in the southeast seem to be larger than in the northwest. There were general patterns ordinal variation in all traits measured.
