There are light intensity, temperature, CO2, humidity, and fertilization in the environmental conditions of greenhouse cultivation of tea. The influence of temperature on bud break and shooting of tea was studied in this study. The bud breaking of tea was increased as the temperature went up. The buds of all cuttings were broken in 15 days when the cuttings had been placed in a growth chamber at 30℃. It took 27 days for the cuttings kept at 20℃. Under the natural condition, the buds of tea plants broke at April 10th. When the cuttings were moved from the field into a growth chamber at 25℃ starting from December 25th at 10 days' interval, the time required for bud breaking could be decreased by 5 days for every 20 days kept at the growth chamber. The shooting responses of the 5 varieties tested to temperature were similar to each other. The optimum temperature for the shooting of the tea was found to be 25℃. The photosynthesis rate increased significantly as the temperature went up to 25℃, then decreased at temperatures higher than 30℃.
