摘要 从澳大利亚引进的细叶桉15个种源在海南省东部进行种源试验。5年生结果表明,种源间的树高、胸径、材积、保存率、干形和抗风性能等指标存在极显著差异,其中树高生长以来自昆士兰州的Kennedy河种源(13443)和MT.Garnet种源(13544)最好,分别为12.68m和12.66m。胸径生长以来自巴布亚新几内亚的种源(13418)为最好(9.05cm)。高纬度维多利亚州种源(13303)生长最差,树高8.48m,胸径6.23cm,材积10.10m3/hm2。最好种源的树高、胸径、材积分别为最差种源的149.35%、145.50%、606.24%。 A provenance trial of Eucalyptus tereticornis with 15 provenances introducedfrom Australia has been carried out in eastern Hainan Island.The results show that therehave been significant differences in tree height,DBH,timber volume,current survival rate,stem form and wind-resistance among the 5-year-old trees of the fifteen provenances. Theprovenances from Kennedy River, Queensland (13443)and MT. Gannet (13544)with heightgrowth of 12.68m and 12.66 m respectively are the best ones. The provenance from PapuaNew Guinea(13418 )with DBH growth of 9.05 cm is the best one. And the high latitudeprovenances from Wictoria(13303)is the worst one in growths of tree height,DBH and tim-ber volume with 8.48 m,6.23 cm and 10.10m3/hm2 respectively. The growths of treeheight,DBN and timber volume of the best provenances are respectively 149.35%,145.50%and 606.24% of that of the worst one.
