【Abstract】 Resin samples of 37 provenances were collected from masson pine genepool in Fuyang County,Zhejiang Province,and 13 chemical components were analysed.It was mea-sured that there were evident negative geographical variation pattern among provenance lati-tude and longifolene,trans-carypohyllene,sesquiterpene,pimaric acid,isopiramic acid,palustric acid+levopimaric acid and diterpene contents,significant correlation between monoterpene content and provenance longitude,negative correlation between neoabietic acid content and provenance yearly precipitation,and correlation between longifolene,pimaric acid contents and provenance cumulative temperature.According to the main component and cluster analyses from 13 resin components it showed that China’s masson pine provenances could be divided into three geographical categories:the southern,middle-eastern and north-ern geographical patterns.更多还原
