1. The relation between the flower development of the tea plant and the air temperature was researched from the point of view of the flower developing speed of the tea shoot under various conditions of the air temperature in each plucking season.<BR>2. The higher the air temperature, the more speedy the flower development, and the hastening effect was not increased by only the maximum temperature in daytime, but was increased by the mean maximum air temperature, especially by the night temperature.<BR>3. The integrated minimum air temperature from the sprouting stage to the flower differentiating stage was about 800°C. and the flower differentiating day was correlated with the mean air temperature, especially with the mean of the minimum air temperature in each day.<BR>4. The low temperature at the time of the flower differentiating stage was unfavorable, therefore the flower development was very delayed or the differentiation was not observed, and it was recognized that some buds altered from the flower-bud to the leaf-bud.<BR>5. Total nitorogen, total carbohydrate and C-N ratio of the tea shoot were affected by the growth stage and also by the air temperature, but the relation between the flower differentiation and the C-N ratio was not clearly observed.
