摘要:
定量分析了来自我国15 个种源(25°~ 42° N,95°~ 117° E)小叶杨Populus simonii 一年生幼苗节间长度的相关性、表型性状的地区差异性以及变异性,将选取的样本划分为4 个时期并借助因子分析对其23 ~ 26 个节间长变量进行了相关性分析,借助人工蜂群K-means 聚类(KABC)算法将样本分为2 大类;并对不同地区样本表型变异定量分析。结果表明,因子分析将节间长度变量提取为4 个公共节间长度因子,且每个因子由相邻的节间长度变量组成;KABC 能较明显地根据小叶杨幼苗的表型性状(株高、叶片数、节数和4 个公共节间长度因子)进行分类,第二类样本在株高、叶片数、节数性状上的均值大于第一类样本;15 个种源7 个表型性状的平均变异系数为6.09% ~ 40.22%,具有较丰富的遗传多样性;平均表型分化系数为17.6%,且种源内变异大于种源间变异。小叶杨幼苗节间长度的相关性反映了幼苗生长特性,对小叶杨幼苗表型性状的关联分析可用于林业的多性状选择育种,也为进一步全基因组关联分析奠定了基础。
Abstract:
Measurements on April 29th, May 20th, June 4th, June 17th 2017 were carried out on height, leaf number, internode length and number of 1-year Populus simonii seedlings from 15 provenances.Quantitative analysis on internode length of tested provenances demonstrated that the upper part had faster growth, and neighboring internode had similar growth rate.Analysis by K-means clustering (KABC) algorithm on phenotypic traits variation of samples resulted that mean coefficient of variation ranged 6.09%-40.22%, indicating rich genetic diversity.The average phenotypic differentiation coefficient was 17.6%, and the variation within provenances was greater than that among provenances.
