基于因子分析和聚类分析的30份山黄皮种质资源评价

选取单果重、果实纵径、果实横径、果形指数、单种重、种子纵径、种子横径、可食率、可溶性固形物含量9个性状指标对30份山黄皮种质资源进行评价。结果表明,山黄皮果实的单果重变异幅度最大,果形指数的变异幅度最小;除可溶性固形物含量与其他8个性状相关性不显著外,其余各指标之间大都存在显著或极显著的相关性;采用因子分析和聚类分析将30份山黄皮种质聚为3大类,山黄皮种质资源的果实性状与地理起源有一定的相关性。其中,来自广西龙州县和宁明县的13份山黄皮种质的果实性状表现最好。

Evaluation of 30 Species of Clausena anisum-olens (Blanco) Merr. Germplasm Resources Based on Factor Analysis and Cluster Analysis

In order to evaluate the germplasm resources of 30 species of Clausena anisum-olens (Blanco) Merr., nine fruit traits including weight of single fruit, fruit equatorial diameter, fruit transverse diameter, fruit shape index, weight of single seed, seed equatorial diameter, seed transverse diameter, edible rate, soluble solid content were measured and analyzed by statistical analysis. The variation of weight of single fruit of C. anisum-olens (Blanco) Merr. was the most significant, while the variation of fruit shape index was the most non-significant. The soluble solid content was not correlated with the other eight indices significantly, and there was significant and extremely significant correlation between the other indexes. Thirty species of C. anisum-olens (Blanco) Merr. germplasm resources were clustered into three categories by factor analysis and cluster analysis. There was a certain correlation between fruit trait and geographical origin. Fruit traits of 13 germplasm from Longzhou County and Ningming County were the best.
