| 摘 要： | 对12个桉树无性系进行了生长、分枝、通直度、树皮厚度及抗风性进行研究,表明无性系间的性状指标均达到极显著或显著差异,E11和E7号无性系的单株材积分列第1、2位并显著高于其它10个参试无性系;用聚类分析方法将12个参试无性系分成6类,可根据实际情况需要进行选择.以产量、形质指标为选择目标,可选择E7、E11、E2、E8、E3号5个无性系;以抗风性强作为首选指标,则可选择抗风性强、产量中等至较好、形质中等的E12、E5、E1、E10、E6号无性系.

| Abstract: | The growth, branch, straightness degree, bark thickness and wind-resistance of 12 Eucalyp- tus clones were studied. The results showed that there were extremely significant differences or significant differences among the traits of tested clones. The clone E11 had the highest individual volume, and the second was the clone E7, which of them were significantly higher than other ten tested clones. The 12 tested clones were classed into 6 groups by cluster analysis, which could be selected according to the ac- tual situation. Five best clones were selected according to yield and form quality, namely E7, El 1, E2, E8 and E3. Five best clones were selected according to wind-resistance, namely El2, E5, El, El0, E6, which were high wind-resistance, moderate yield and moderate form quality. |
