Application of chlorophyll fluorescence technique has shown a favorable prospect in the research field for plant resistance. In the present research, referring to the measurement results by electrolyte conductivity method, appropriate chlorophyll fluorescence parameters were studied for the determination of cold resistance of tea plants. The results showed that the cold resistance of different tea cultivars measured by chlorophyll fluorescence parameter Fv/Fm with logistic equation was the same as which were obtained by electrolyte conductivity method: cv.Shuchazao> cv.Wancha91> cv.Pingyangtezao. However, the determination conclusions by Fv/Fo, Fm and Fo were not correspond to the result acquired by electrolyte conductivity method. For the determination of plant resistance, we concluded that chlorophyll fluorescence method is more convenient and less interfered than the traditional electrolyte conductivity method. Therefore, it was treated as a new method to identify the cold resistance of tea plants.
