How seasonal temperature or water inputs affect the relative response of C3 c…

Rising atmospheric carbon dioxide concentration ([CO2]) has the potential to positively impact C3 food crop production by directly stimulating photosynthetic carbon gain (A), which leads to increased crop biomass and yield. Further stimulation of A and yield can result from an indirect mechanism in which elevated [CO2] decreases stomatal conductance and canopy water use, ameliorating droug…
