Abstract

The effect of elevated CO2 on the productivity of spring wheat Triticum aestivum, winter wheat and faba bean Vicia faba was studied in experiments in climatized crop enclosures in the Wageningen Rhizolab in 1991-93. At the end of the growing season, above ground biomass increase at 700 μmol mol-1 was 58% (faba bean), 35% (spring wheat) and 19% (winter wheat) and the harvest index did not change. For spring wheat the simulated responses (35-50%) were at the upper end of the experimental results. In agreement with experiments, simulations showed smaller responses for winter wheat and larger responses for faba bean. Further model explorations showed that this differential effect in the CO2 response may be at least partly due to differences in the daily air temperatures during comparable growth stages. -from Authors
