摘　　要：The trial of 21 eucalyptus species/provenances at the 4.5 year old established at Kaiping City of Guangdong Province were analyzed.The results show that there are distinct differences on the increments of height,DBH and volume at the 4.5 year old among 8 species with different provenances,and Eucalyptus urophylla is the best species among 8 species.Among 5 provenances of E.urophylla ,Mandiri provenance (Seedlot No.17564) is the best provenance with a mean height,mean DBH,mean individual volume and volume increment of 13.44 m,11.45 cm,0.065 6 m 3 and 22.52 m 3·hm -2 ·a -1 respectively,which are respectively 1.49,1.87,6.02 and 6.24 times compared with that of E.exserta as contrast. E.urophylla from Mandiri is suggested to be extended in this area and carry out the genetic improvement based on E.urophylla from Mandiri provenance.The trial of 21 eucalyptus species/provenances at the 4.5 year old established at Kaiping City of Guangdong Province were analyzed.The results show that there are distinct differences on the increments of height,DBH and volume at the 4.5 year old among 8 species with different provenances,and Eucalyptus urophylla is the best species among 8 species.Among 5 provenances of E.urophylla ,Mandiri provenance (Seedlot No.17564) is the best provenance with a mean height,mean DBH,mean individual volume and volume increment of 13.44 m,11.45 cm,0.065 6 m 3 and 22.52 m 3·hm -2 ·a -1 respectively,which are respectively 1.49,1.87,6.02 and 6.24 times compared with that of E.exserta as contrast.
