摘要 对武夷山茶区42份武夷名丛茶树资源的主要生化成分进行了评价鉴定和遗传多样性分析。结果发现,武夷山茶树资源的生化成分存在丰富的多样性和变异,平均遗传多样性指数达到2.06%,平均变异系数达到22.01%。通过多变量的主成分分析,前3个主成分代表了茶树生化成分多样性的89.02%的信息。基于生化成分,把42份武夷名丛聚类划分为3个类群。3个类群除了咖啡碱含量差异不显著外,其他各生化成分均存在显著差异。第Ⅰ、Ⅱ类群大部分为适制乌龙茶的资源,第Ⅲ类群大部分为适制绿茶的资源。并从中筛选出一批生化成分特异的资源。 Biochemical composition and diversity analysis of 42 Wuyi Mingcong tea germplasms from Wuyi mountain tea area. The results showed that the biochemical diversity and variation were high in Wuyi Mountain tea germplasms. The average diversity index and coefficient of variation were 2.06% and 22.01% , respectively. In principal component analysis ,the first three principal components represented 89.02% of the biochemical diversity. Based on the biochemical data,42 Wuyi Mingcong were clustered into 3 groups. In addition to the caffeine content, other biochemical components exist significant difference of 3 groups. Most of the tea germplasms in the first and the second group suited to be processed Oolong tea. Most of the tea germplasms in the third group suited to be processed green tea. A set of special germplasms on some biochemical composition were selected.
