摘要: A model is presented which enables gas exchange data to be used partition the intracellular resistance leaf photosynthesis into carboxylation and transport components. basic assumption that over-all kinetics of reaction fit Michaelis-Menten equation. The was tested for cotton ( Gossypium hirsutum L., var. Deltapine Smoothleaf), where photorespiration suppressed by using mixtures containing less than 1.5% oxygen. It concluded formed major component plants studied. However, in some cases factor limiting photosynthesis, at an ambient CO 2 concentration 600 ng cm −3 , system, close saturation.
