We used a modified functional balance (FB) model to predict growth response of Helianthus annuus L. to elevated CO2. Model predictions were evaluated against measurements obtained twice during the experiment. There was a good agreement between model predictions of relative growth rate (RGR) responses to elevated CO2and observations, particularly at the second harvest. The model was then used to compare the relative effects of biomass allocation to roots, nitrogen (N) uptake and photosynthetic N… CONTINUE READING
