What have we learned from 15 years of free-air CO2 enrichment (FACE)? A meta-analytic review of the responses of photosynthesis, canopy properties and plant production to rising CO2. (2004, background): “In the SoyFACE experiment, non-nodulating soybeans showed downregulation of Vc,max in elevated [CO2], while nodulating varieties maintained the same photosynthetic capacity under ambient and elevated [CO2] (Ainsworth et al., 2004).”
Preserving the nutritional quality of crop plants under a changing climate: importance and strategies (2019, background): “However, longer treatments with eCO2 might lead to photosynthetic acclimation, due to increased soluble sugars leading to an imbalanced C:N ratio, accelerated leaf senescence and/or limited growth rate (Ainsworth and Long 2005; Ainsworth et al. 2004; Kaplan et al. 2012; Ludewig and Sonnewald 2000).”
Can improvement in photosynthesis increase crop yields? (2006, background): “Ainsworth et al. (2004) further analyse this by combining genetic manipulation of sink capacity with growth of soybean at current and elevated [CO 2 ].”
Elevated CO2 effects on plant carbon, nitrogen, and water relations: six important lessons from FACE. (2009, background): “A meta-analysis of SoyFACE results indicates an average 16% increase in Asat across a variety of soybean cultivars, which is substantially smaller than suggested by chamber studies (Fig.”
Impacts of Changing Climate and Climate Variability on Seed Production and Seed Industry (2013, background): “are expected to increase in the range of 10–20% for C3 crops and 0–10% for C4 crops (Ainsworth et al., 2004; Gifford, 2004).”
Cassava about‐FACE: Greater than expected yield stimulation of cassava (Manihot esculenta) by future CO2 levels (2012, background): “© 2012 Blackwell Publishing Ltd, Global Change Biology, 18, 2661–2675 lower sink strength early in the season as insufficient sink capacity increases photosynthetic acclimation to elevated [CO2] in crops and trees (Ainsworth et al., 2004; Takeuchi et al., 2001).”
