| 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6．30～7．72cm，平均树高为5．87～9．18m，都表现出速生特性。6个无性系间的树高生长存在极显著差异，胸径生长量存在显著差异。尾赤桉和尾巨桉5个无性系间树高生长也存在极显著差异，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易风倒现象。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: | The early growth performance and resistance to environmental stress of six Eucalyptus clones including Eucalyptus urophylla x E. grandis （ DH-33-27, DH-33-29, Guanglin 9 ）, E. urophylla x E. camaldulensis （201,201-2） and E. urophylla （U6） were investigated in Shaoguan. The results indicated that all alones grew fast. The average height was 5.87 -9.18 m, the diameter at breast height was 6.30 -7.72 cm. There were very significant differences of height growing among six clones, significant differences of breast diameter growing, but indistincfive of breast diameter growing between clones of E. urophylla x E. grandis and E. urphylla ~ E. camaldulensis. U6 and DH-33-29 were appraised with relatively faintish resistance to the cold, 201 and 201-2 were easy lodging by wind. Clones DH-33-29 and Guanglin 9 were available for planting in Shaoguan city. |
