The Chinese rice cultivar Ai-Nam-Tsao was grown to maturity in two replicate experiments under three CO2 treatments or three temperature treatments in growth chambers for the purpose of exploring the root growth dynamics of rice under possible future climatic changes. Root and shoot growth was significantly enhanced by both elevated CO2 treatments. There was no difference between elevated CO2 treatments. Roots responded much more to CO2 than did shoots. Because rice root biomass is closely coupled to methane emissions from rice paddies, information about root responses will prove useful in modeling potential future changes in methane emissions under climate change.
