Abstract:

Tea plant is affected by adverse conditions at any time as it grows, such as high or low temperature, drought, high light, etc. It is of significance in resistance breeding, identifying the resistance, screening out the resistant materials and setting up the early-warning and regulation mechanism to study how tea plant resist to environmental stress, ascertain and build up physiological evaluation system with all kinds of new technique and testing method. Based on the current study situation in agriculture, this paper explicated the research progress on physiological evaluation of tea plant resistance mainly from the following aspects. They were anti-oxidative enzyme activities, organization structure, MDA, electrical conductivity and soluble sugar content, etc. Two realizations were suggested: ①Have the theoretical research of resistance to stress of environment and lasting resistance to stress; ②Screen out physiological indexes of tea plant resistance and evaluate them.
