摘 要: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。

Abstract: In order to evaluate the germplasm resources of 30 species ofClausena 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 ofC. 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 ofC. 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.

山黄皮[Clausena anisum-olens(Blanco) Merr.]为芸香科(Rutaceae)黄皮属(Clausena)多年生常绿大灌木或小乔木,俗称“鸡皮果”,又名细叶黄皮,主要分布于北回归线以南的南亚热带地区,主产于我国广西西南部的百色和龙州、云南南部的蒙自和河口、广东的新会和鹤山及越南北部和菲律宾[1-2]。山黄皮果实为浆果,果皮、果肉可食,果实中糖类、蛋白质、维生素等含量丰富,还含有铁、钙等各种营养元素,营养价值高。山黄皮以其可口的酸甜味及香气在芸香科水果中独具一格,可加工成山黄皮干、果脯、果酱、饮料等制品,其产品消腻开胃,风味独特,具有化痰止咳、祛风除湿的功效,深受消费者的欢迎[2-3]。
目前对山黄皮的研究主要集中在种质资源收集评价及其遗传多样性分析方面。……
