摘　　要：为系统分析不同品种杨梅果实香气成分的差异,采用气相色谱—质谱联用(GC-MS)技术,对10个品种杨梅果实进行分析鉴定,并结合DPS软件进行聚类分析.结果表明:烷烃和烯烃在10个品种中均检出,是杨梅果实最主要的香气成分;醇类和酯类在8个品种中检出;酮类和芳香烃只在5个品种中检出;荸荠种是唯一含有6个香气种类的品种.聚类分析显示,产自福建的6个杨梅品种较好地聚在一类,与另外4个产自浙江的品种遗传差异较大.ParsOn and oldln were the major aroma categories, which were found to be present in all the ten Chinese bayberry（ Myrica rubra Sieb. et Zucc） cuhivars tested.
