以伊犁野果林13个不同居群分布的87份新疆忍冬为试材,采用嵌套方差分析、主成分分析、聚类分析等统计学方法,对枝条、叶片、花、果实的16个表型性状进行分析,研究了新疆忍冬种质资源表型性状的多样性和遗传变异来源,以期为现有新疆忍冬资源的保护、应用及多样化开发提供参考依据.结果表明:供试的87份新疆忍冬种质资源表型平均变异系数为29.00%,Shannon-Wiener多样性指数范围在1.06~1.89,均具有较大的离散程度.表型分化系数为16.85%~70.68%,伊犁野果林新疆忍冬植物表型变异主要来源于群体间.主成分分析提取5个特征值大于1的主成分,这5个主成分累积贡献率达到56.98%.新疆忍冬表型性状差异的主要因素是叶片各性状,其次是新梢,以及果实的部分性状,花表型影响较小.新疆忍冬各居群聚类结果基本与地理位置相近,乌图布拉克居群较为特殊.综上,新疆忍冬作为伊犁野果林的重要伴生种,对自然环境的适应性较强,多样性较丰富.
Phenotypic Diversity Analysis of Lonicera tatarica L.in Yili Wild Fruit Forest
The 87 Lonicera tatarica L.germplasms distributed in 13 natural populations in Yili wild fruit forest were used as experimental materials.The 16 phenotypic traits of branches,leaves,flowers and fruits of Lonicera tatarica L.were analyzed by nested analysis of variance,principal component analysis and cluster analysis.The diversity and genetic variation sources of phenotypic traits of Lonicera tatarica L.germplasm resources were studied,in order to provide reference for the protection,application and diversified development of the existing Lonicera tatarica L.resources in Xinjiang.The results showed that the average phenotypic variation coefficient of 87 Lonicera tatarica L.germplasm resources was 29.00%,and the Shannon-Wiener diversity index ranged from 1.06 to 1.89,all of which had a large degree of dispersion.The phenotypic differentiation coefficient was 16.85%-70.68%,and the phenotypic variation of Lonicera tatarica L.in Yili wild fruit forest mainly came from the population.Principal component analysis extracted five principal components with eigenvalues greater than 1,and the cumulative contribution rate of these five principal components reached 56.98%.The main factors affecting the phenotypic traits of Lonicera tatarica L.were leaf traits,followed by branch,some traits of fruits,and the flower phenotype has little effect.The clustering results of each population of Lonicera tatarica L.were basically similar to the geographical location,and the Utubulak of Gongliu population was more special.In summary,as an important companion species of Yili wild fruit forest,Lonicera tatarica L.had strong adaptability to the natural environment and rich diversity.
