A model of stomatal control



A model of stomatal control



Photosynthetica (Prague) 16(4): 486-495



Stomata respond to CO2 concentration, and recent experiments indicate that they maintain the CO2 concentration inside the leaf at a constant fraction of the concentration outside the leaf. This relationship may be the basic equation of the mechanism which controls stomatal aperture rather than the usual assumption that the stomata maintain a constant intercellular CO2 concentration. Apparently, stomata respond to changes in photosynthetic rate, not the reverse. The mechanism of this is not clear, but some suggestions are made as to how it could arise from the uptake of CO2 by both guard and mesophyll cells.
