Growth under elevated CO2 concentration affects the temperature response of photosynthetic rate

Does long-term cultivation of saplings under elevated CO2 concentration influence their photosynthetic response to temperature?

BACKGROUND AND AIMS Plants growing under elevated atmospheric CO2 concentrations often have reduced stomatal conductance and subsequently increased leaf temperature. This study therefore tested the hypothesis that under long-term elevated CO2 the temperature optima of photosynthetic processes will shift towards higher temperatures and the thermostability of the photosynthetic apparatus will inc...

Photosynthetic parameter estimations by considering interactive effects of light, temperature and CO2 concentration

Biochemical leaf photosynthesis models are evaluated by laboratory results andhave been widely used at field scale for quantification of plant production,biochemical cycles and land surface processes. It is a key issue to search forappropriate model structure and parameterization, which determine modeluncertainty. A leaf photosynthesis model that couples the Farquhar-vonCaemmerer-Berry (FvCB) f...

Variability in Growth and Yield Response of Maize Genotypes at Elevated CO2 Concentration

The changing climatic conditions are expected to increase the atmospheric CO2 concentration, temperatures and alter the precipitation pattern. Atmospheric CO2 concentration is predicted to reach 550ppm by 2050, and probably exceed 700ppm by the end of this century [1]. These changes are anticipated to affect the production and productivity of agricultural crops and influence the future food sec...
