摘　　要：不同种源巨桉生长与材性变异王豁然，柴修武，郑勇奇，臧道群，方玉霖，王维辉关键词巨桉，种源，材性变异在我国南方，巨按（ＥｕｃａｌｙｐｔｕｓｇｒａｎｄｉｓＷ．ＨｉｌｌｅｘＭａｉｄｅｎ）是生长最快的桉树之一，现已被选作世界银行贷款国家造林项目的主要树种。中...There were very significant differences in volume growth between the overall15 provenances,which were involved in the test,of Eucalyptus grandis Hill ex Maid.,prove-nances of north Queensland performed better than the others,one seedlot of Coff's Harbotirand seed sources from the seed orchard of South Africa were relatively inferior.It was notfound that any significant variation existed in wood density between provenances,however,tree to tree variation within the species was considerable in the range from 350 to 670 kg/m3with mean value of density 432 kg/m3.
