摘　　要：广西三门江林场参试的6个无性系分别来自巨尾桉(E.grandis)、尾赤桉(E.urophylla×E.camaldulensis)、柳窿桉(E.saligna×E.exserta)等3个杂交种和1个尾叶桉(E.urophylla)纯种,均有较高的生长水平,林龄44个月时它们的年平均蓄积生长量达到31.34 m3/hm2,树高、胸径、蓄积生长量从林龄8个月到44个月时均无显著差异,但以造林编号为3(巨尾桉)、5(巨尾桉)、4(尾叶桉)的无性系生长较好;另外,无性系生长稳定性高,早期选择可靠性大。Initial study was carried out on the growth performance of 6 clonal E. urophylla and hybrid Eucalyptus （E. saligna × E. exserta, E. grandis × E. urophylla, E. urophylla × camaldulensis ） . It was found that all these 6 clones were of high growth performance. Yearly mean volume growth reached 31.34m^3/hm^2 at 44^th month. Tree hight, DBH and volume growth displayed little difference from 8^th month old to 44^th month old. However, the clones labeled No.3 （E. grandis × E. urophylla ）, No.5 （E. grandis × E. urophylla ） and No.4 （E. urophylla ） grew well. In addition, growth stability of clones were high and early-stage selection was reliable.
