Description	Leaf-level measurements have shown that mesophyll conductance (g(m)) can vary rapidly in response to CO(2) and other environmental factors, but similar studies at the canopy-scale are missing. Here, we report the effect of short-term variation of CO(2) concentration on canopy-scale g(m) and other CO(2) exchange parameters of sunflower (Helianthus annuus L.) stands in the presence and absence of abscisic acid (ABA) in their nutrient solution. g(m) was estimated from gas exchange and on-line carbon isotope discrimination (Delta(obs)) in a 13CO(2)/12CO(2) gas exchange mesocosm. The isotopic contribution of (photo)respiration to stand-scale Delta(obs) was determined with the experimental approach of Tcherkez et al. Without ABA, short-term exposures to different CO(2) concentrations (C(a) 100 to 900 mu mol mol-1) had little effect on canopy-scale g(m).
