Observations of nonuniform photosynthesis across leaves cast doubt on internal CO(2) partial pressures (p(i)) calculated on the assumption of uniformity and can lead to incorrect conclusions about the stomatal control of photosynthesis. The problem can be avoided by measuring p(i) directly because the assumptions of uniformity are not necessary. We therefore developed a method that allowed p(i) to be measured continuously in situ for days at a time under growth conditions and used it to… CONTINUE READING
