Results showed that 50d after inoculation, the chlorophyll content in tea leaves inoculated by VA mycorrhiza was higher than that uninoculated by VA mycorrhiza. Results also indicated when the photosynthetical available radiation was in the range of 0~1200μmol/m2·s, the net photosynthesis rate, the stomata conductance and the transpiration rate of the tea plant inoculated by VA mycorrhiza were all higher than those of the control, the water use efficiency (WUE) increased rapidly in earlier stage, then decreased gradually after reaching the peak, the degrees of saturation of leaves decreased gradually. After the tea plant inoculated by VA mycorrhiza, MDA content of tea leaves decreased while the hydroxyproline content decreased first and increased later with the increase of infection rate. The inoculation of VA mycorrhiza can improve the activities of protective enzymes of tea plant. During the resied of 90d after inoculation, the activity of POD reached the peak, the activity of SOD increased slightly first and then decreased smoothly. CAT activity of tea plant treated by VA mycorrhiza was always higher than that of the control.
