| 摘 要： | 通过对31个柳树无性系5种数量性状的主成分分析,将柳树无性系划分为3个区,第一和第二区为密枝型,第三区为疏枝型,第二区株型较宽,第一区株型中等,第三区株型较窄。从而为柳树无性系进行田间试验及造林提供了依据。 |
| 关 键 词： | 柳树 无性系 数量性状 主成分分析 |

| Abstract: | Willow clones were divided into 3 regions by principal component analysis of 5 kinds of quantitative characteristics for 31 species of willow.The region 1 is medium-dense-crown type,the region 2 is wide-dense-crown type,the region 3 is narrow-sparse-crown type.It provides basis for planting and testing willow clones. |
| Keywords: | willow clone quantitative characteristics principal component analysis |
