野生茶树种群的形态与分布研究

STUDIES ON THE SHAPE AND DISTRIBUTION OF THE WILD TEA-TREE GROUPS

本文以作者实地考察与研究成果为主要依据,综合各地研究资料,进行系统整理,提出野生茶树分为“三江”、“滇东——桂西”、“川南——黔北”和南岭等四大种群的论点;同时将其总群与其中的苦味茶和已分类命名的“茶组”植物种的分布进行分开讨论,其目的在于揭示野生茶树资源的内外关系,探讨茶树起源中心与演化趋势,并提出以野生茶树总群的分布中心为茶的起源中心的见解。

1. The wild 'tea-tree , groups' in this paper is the original wild tea-trees that can be drunk and distribute depending' on. natural spreading and growing in original forest. 2. According to the properties of shapes and characteristics of ecology, wild tea-trees can essentially be grouped into four groups. 'Three River' , 'East of Yunan-West of Guanxi' , 'South of Sichuan-North of Guizhou'and 'Nanjing' . The tree statures of the first two groups are taller and larger, their leaves are larger and thinner, while the tree types of the othe two groups are shorter, their leaves are thicker. 3. It is recognized that the originating center region of tea-tree is the center (98°-108°E, 22°-29°N) of all groups of the wild tea-tree.
