52份茶树资源生化组分的表型多样性分析

Phenotypic Diversity Analysis of Biochemical Composition in 52 Tea Germplasms

对四川地区33个和从省外引进的19个茶树资源的主要生化成分(包括水浸出物、茶多酚、氨基酸、咖啡碱、儿茶素总量、酯型儿茶素总量、简单儿茶素总量等)进行鉴定和多样性分析。结果表明:参试的茶树资源生化组分存在丰富的多样性和变异;并以茶树资源生化成分为基础,可将52份茶树资源分为A、B两个组群。

Biochemical components （including water extracts, polyphenols, amino acids, caffeine and catechins etc.） and genetic diversity in spring shoots were analyzed in 52 tea germplasms from Sichuan（33 germplasms） and other provinces（19 germplasms）. The results showed that the biochemical diversity and variation were significant in these 52 tea gemplasms. Based on the biochemical composition data, 52gemplasms were clustered into two groups.
