Short summary
Few researchers have investigated post-photosynthetic 13C fractionation happening in leaves. Potted saplings were cultivated under orthogonal treatments of CO2 concentration and soil water content. The 13C fractionation from mesophyll conductance and post-carboxylation both contributed to the total 13C fractionation that was determined by δ13C of water-soluble compounds and gas-exchange measurements.
