摘要
调查湖北省恩施地区茶树有性群体中的变异单株,对各样株的定型叶及嫩梢共17个性状作了观察和测量;经常规变异类型分析及聚类分析,初步阐明了该地区茶树有性群体内的变异类型分布状况,并按其变异状况划分为5个类群。从而为茶树资源保护及群体改良提供了方法和理论依据。
The group variation in sexual propagation of tea tree in Enshi of Hubei province was studied through survey and analysis on the varied individual within the sexual propagated group. Seventeen characteristics of sample trees including finalized leaf and tender shoot were observed and measured, routine analysis on variation types and cluster analysis were conducted. The study basically revealed the variation distribution with the sexual group of tea tree at Enshi of Hubei. The sexual group of tea tree at this region was divided into five categories. The study provided the tea tree protection and group improvement with some methods and theoretical foundation.
