Abstract
The isotopic CO2 technique for measuring photorespiration was shown to be a valid technique for measuring the unidirectional inward and outward fluxes of CO2 from a sunflower (Helianthus annuus L.) leaf in the light. The rate of photorespiration was decreased little as the CO2 concentration was increased from 20-1150 .mu.l/l. This finding contradicts the widely held assumption that photorespiration is suppressed at high CO2 concentrations. Some discussion regarding this apparent conflict is presented.Keywords
