The optimization model of photosynthesis predicts stomatal response to changing oxygen concentration. According to the optimization statement, a decrease in oxygen concentration will result in a decline in CO{sub 2} concentration in the leaf intercellular spaces (c{sub i}), accompanied by an enhancement of photosynthesis. Because we have failed to find satisfactory data in the literature, we estimated the predicted changes in c{sub i} by 30-50 ml/l and increase photosynthesis by 40%. These estimates are consistent with the literature data. Futhermore, the predictions of the model were directly confirmed by the data obtained on six plant species. 14 refs., 2 tabs.
