Abstract:

In order to obtain the tea varieties with cold resistance, and improve the capability of cold disaster prevention and mitigation of tea gardens, the cold resistances of 24 tea varieties were studied with the methods of natural infection, leaves anatomical structure and electrical conductivity. The results showed that the stronger cold resistance varieties were ‘Zhenong 113’, ‘Zhongcha 102’, ‘Cuifeng’, etc. The cold resistance orders of the tea varieties were different in the three methods, and the synthetic identification result was more reliable than any one of the three methods according with the actual production.
