摘要
分析研究云南3个紫斑百合居群核型变异,应用常规统计方法和巢式分析方法,在常规染色体水平上探讨紫斑百合居群间、个体间、细胞间和同源染色体间的变异式样。用巢式方差等级分析表明,紫斑百合染色体结构变异有4.5%左右来源于居群间,有95.5%左右来源于居群内个体间、细胞间和同源染色体间。
Karyotype in three populations(P_1,P_2,P_3) of lilium nepalense D.Don was analyzed in this paper. All the populations exist and are scattered in Yunnan. The karyotypical variation patterns among the populations,individuals,cells,homologous chromosomes were respectively studied in chromosomal level by using routine statistic and nested analysis.The nested analysis of variance shows that about 4.5% of the chromosomal variability is attributed to the differentiation among populations and the remaining 95.5% within population.
