Description	Mesophyll conductance (gm) and stomatal conductance (gs) are two crucial components of the diffusive limitation of photosynthesis. Variation of gm in response to CO2 concentration was evaluated by using two independent methods based on measurements of variable electron transport rate (J) and instantaneous carbon isotope discrimination, respectively. Both methods of gm estimation showed a very similar shape of the gm/Ci relationship, with an initial increase at low substomatal CO2 concentrations (Ci), a peak at 180-200 micromol per mol of air and subsequent decrease at higher Ci. Plants were also treated with abscisic acid (ABA) which induced a reduction in gs without significantly affecting the rate of photosynthesis, gm or the photosynthetic capacity. The results confirm, that gm is strongly sensitive to Ci and that the relationship between gs and gm is not conservative , differing between control and ABA-treated sunflower plants.
