云南栽培大叶茶资源的多样性和优质性

THE DIVERSITY AND QUALITY OF YUNNAN CULTIVATED LARGE LEAF TEA RESOURCES

按茶树植物学形态标准,叶面积>40cm^(2)为大叶。云南统称的大叶茶包括野生型和栽培型茶树。在张宏达的植物学分类系统的32个种4个变种中(见1998年《中国植物志》一山茶科),云南有23个种3个变种,占总数的76.5%。其中以云南作模式标本的种有18个,占茶种数的51.4%。

According to the botanical morphological standards of tea trees,the leaf area≥40cm:falls inot the category of the large-leaf tea,which in Yunnan encompasses the wild type and the cultivated type.Among the 32 species and 4 varieties in Zhang Hongda's botanical classification system,there are 23 species and 3 varieties in Yunnan,accounting for 76.5%of the total Among them,18 species are yunnanensis species,accounting for 51.4%of the total The concentration of that much variation in an area of380f000 square kilometers is unique on a global scale.This also proves that the place with the most tea species is also the area with the most genetic accumulation,proving to be the original center of tea trees.So Yunnan deserves to be is the world’s"tea tree kingdom".
