| Abstract: | Employing the method of paraffin production technology,the leaves anatomical structure of 18 native tea cultivars and 8 foreign tea cultivars was analyzed.The result showed:the coldr esistance of native tea cultivars in Shaanxi province was better than foreign tea cultivars.Comparing with foreign tea cultivars,the leaves of native tea cultivars were smaller in shape,having more layers of palisade tissue layers,and the ratio of Palisade tissue and to spongy tissue and the ratio of skin and spongy tissue were higher.The research laid the foundation of the breeding of cold resist ant tea cultivar,and the results provided a reference for the introducing of tea cultivar in northern tea cultivated region. |
