Experiments were performed, using rice, barley and Hydrangea leaves, to examine the re-assimilation of respiratory ^<14>CO_2 while photosynthesis is going on in an open air flow system. It was found that the leaves which had assimilated ^<14>CO_2 before-hand evolved, when kept under photosynthesizing conditions, three to four tenths (variable according to plant species and external conditions) of the amount of ^<14>CO_2 to be produced in the dark. Such an incomplete re-utilization of ^<14>CO_2 was observed also in spinach leaf homogenate as well as in the leaves which had previously absorbed ^<14>C-glucose. The ^<14>CO_2 output in rice leaves was found to be accelerated by the light of high intensity. A possibility of light stimulation on the respiration was suggested.
