摘　　要：对１５个尾叶桉无性系１年生幼林的生长进行初步分析，结果表明，无性系间树高生长差异极显著，来自湛江市的Ｕ２和Ｕ８尾叶桉无性系生长最好，尤其是Ｕ２的树高生长是最差无性系Ｕ９的１．３４倍；胸径生长差异显著或不显著；大多数无性系生长表现优于作为对照的优良种源。立地与无性系间的交互作用不显著，无性系在不同立地的效应较为一致。The paper analyzed the growth of young plantation at oneyearold of a clone test for Eucalyptus urophylla established at Zengcheng Forestry Research Institute. The results showed that there were highly significant differences among clones on height growth. U2 and U8 clone from Zhanjiang were superior to others on height growth. Especially, the height growth of clone U2 was 1.34 time than that of U9,which was the worst of all. There were no significant or significant differences among clones on DBH growth in two tested areas. The vast majority of clones performed better than the best provenance as control in the test.The interaction between sites and clones was not significant. The effects of clone under the different sites showed no difference.
