The diurnal and seasonal changes of photosynthesis of tea plant were measured in the tea garden on which some clonal tea varieties were planted.<BR>In the Y2 variety grown garden, the rate of photosynthesis increased rapidly with the increase of light intensity and decreased gradually from just before noon, so a photosynthesis curve of inclined triangular form was observed in winter.<BR>Concerning the light-photosynthesis (apparent) curve in growing season, a light saturation point was observed, but not observed in late autumn and winter.<BR>By calculating the true photsynthesis rate and also by applying 2.0 as Q<SUB>10</SUB>, respiration value, the light saturation point was not observed even in summer, and the photosynthesis increased every time with the increase. of light intensity.<BR>Under high air temperatures, the apparent photosynthesis decreased, but in the true photosynthesis. value such a phenomenon was not observed.<BR>The Q<SUB>10</SUB> respiration value of twigs was 2.25 in summer.<BR>Examining the rate of photosynthesis of twigs, it was observed that the rate was decreased distinctly in winter.<BR>Concerning the light-photosynthesis (apparent) curve of twigs in growing season, a light saturation point was observed, but not observed in winter.<BR>Examining the annual gas exchange rate, it was observed that the accumulation of carbohydrate was proceeding even in winter, and also that the photosynthesis rate was especially large in summer and autumn in tea plant.<BR>No distinct relation between the gas exchange rate and the yield of tea leaves was observed.
