| 摘 要： | 以16个桉树无性系为材料,对其6年生时生长性状进行比较。方差分析表明不同无性系表现出对立地条件较敏感,说明在不同立地条件下进行无性系选择是必要的。聚类分析表明无性系M1、GL9、DH32-22保存率高,生长性状达到中上等水平,是本试验中的较优良品种。无性系亲本分析表明以尾叶桉和巨桉为亲本进行杂交育种具有较大的发展空间。

| Abstract: | The growth differences of sixteen 6-year-old eucalypt clone stands were compared.The variance analysis showed that the growth traits of different clones were sensitive to site conditions,which indicated that it was necessary to select clone for different sites.The results of cluster analysis showed that M1,GL9 and DH32-22 were better clones for their high survivals and good growth traits.It might get good results from using E.urophylla and E.grandis as parents for hybridization. |
