摘    要:为探讨茶树春梢芽叶色泽的数量遗传特性,应用色差仪测定68份茶树品种(品系)春梢芽叶的色泽表型值并进行数量分类研究。结果表明,对叶色差异度较高的第1叶位L~*、a~*、b~*、C、H值进行分层聚类分析,可将芽叶色泽划分为紫色系、黄色系和绿色系等7个色系。色系分类与CIELab颜色体系的对应性较强,色系划分符合茶树品种(品系)叶色表型特点。茶树品系的叶色表型较丰富,叶色在L~*、a~*、b~*值三维坐标空间整体呈带域分布,色系由紫色系、紫红色系、紫绿色系向黄色系、黄绿色系、绿色系变化。春梢芽叶色泽表型数据的遗传数量分类与色系判定为茶树特异芽叶色泽育种提供科学依据。

关 键 词:茶树  芽叶色泽  表型性状  数量分类  分层聚类

Abstract:In order to understand the quantitative inheritance of leaf color of tea (Camellia sinesis) spring shoots, the numerical taxonomy of leaf color phenotypes of 68 tea cultivars was studied by using colorimeter. Based on hierarchical cluster from the values of L*, a*, b*, C, and H of the first leaf, the tea cultivars could be divided into seven groups, such as purple, yellow, and green, et al. The color classification by hierarchical cluster had high identity to the CIELab system, which had close relation to the color phenotypes of tea cultivars. The leaf color phenotypes were rich with a zonal distribution at 3D coordinate of L*, a*, b* values, ranging from purple, purple-red and purple-green to yellow, yellow-green and green. Therefore, the numerical taxonomy of leaf color would provide a scientific basis for breeding special color of tea bud-leaf.
Keywords:Tea  Bud-leaf color  Phenotypic characteristics  Numerical classification  Hierarchical cluster
