• Lettuce, Lactuca sativa cv. Wayahead, and cucumber, Cucumis saliva cv. Nagafushinari No.4, plants were transferred to cabinets maintained at 27℃, continuous irradiation of 2×10^4 lux, 70% relative humidity, and 300ppm or 5,500ppm of atmospheric CO_2. Changes of carbonic anhydrase activity and chlorophyll contents in the leaves were observed for several days. Lettuce leaves at the high CO_2 concentration showed enhanced carbonic anhydrase activity within 1 day which then decreased gradually and a lower chlorophyll content than the control. Cucumber leaves at the high CO_2 concentration showed a similar trend of carbonic anhydrase activity to the lettuce leaves, and gradual decrement of the chlorophyll content. After 126 hours under the high CO_2 concentration, carbonic anhydrase activity levels in leaves of cucumber at the middle position was maximum, when expressed in units per g fresh weight of leaves, and those at the upper position was higher, when expressed in units per mg of chlorophyll content.
