Abstract
Growth of photomixotrophic cell culture of Euphorbia characias L. is described; oxygen exchange rates were measured along this growth cycle using a mass-spectrometric technique. During the exponential and mid-stationary phases, photosynthesis was strongly increasing, the major part of oxygen uptake in the light was due to mitochondrial respiration. In the late stationary phase, gross photosynthesis was decreasing; this could not be explained by an alteration of Rubisco because photorespiratory process could be observed; in addition the Mehler reaction must be called upon to explain whole oxygen uptake in the light.
