| 摘要: |
| 通过对参试的尾巨桉（DH-33-27、DH-33-29、广林9号）、尾赤桉（201号、201-2号）和尾叶桉（U6）6个桉树无性系早期人工林的生长量和抗逆性进行调查和综合评价。结果表明：参试无性系20个月生林分平均胸径6.3-8.4cm，平均树高在5.9-9.3m，都表现出速生特性。6个无性系间的树高生长存在着极显著差异，胸径生长量存在着显著差异。尾赤桉和尾巨桉5个无性系间树高生长也存在着极显著差异，胸径生长量差异不显著。尾叶桉U6和尾巨桉DH-33-29耐寒性较差，尾赤桉系列幼龄林存在着易风倒现象。因此，尾巨桉系列（DH-33-27、广林9号）速生性、适应性较强，可作为目前韶关市桉树人工林建设的主栽品种。 |

| Abstract: |
| Six Eucalyptus clones including E.urophylla×E.grandis (DH-33-27,DH-33-29,Guang’Lin9 ),E.urophylla×E.camaldulensis(201,201-2) and E.urophylla(U6) were investigated and selected by young stage growth and anti-disaster characteristic. The result indicated that all alones have fast-growing characteristic. The average height was 5.9-9.3m, the basal diameter was 6.3-8.4cm. There are very obvious diffence of height growing amone six clones,obvious diffence of basal diameter growing,but have not diffence of basal diameter growing between clones of E.urophylla×E.grandis and E.urphylla×E.camaldulensis. The U6 and DH-33-29 clones are worse of anti-clold characteristic,and the 201 and 201-2 clones are easy lodging by wind.So the clones DH-33-29 and Guang’Lin 9 are available for planting clones in ShaoGuan city. |
