TL;DR: A large, cooperative, integrated experimental program utilizing free-air CO 2 enrichment (FACE) is being conducted to expose plants to elevated concentrations of CO 2. The goals are to evaluate the effects of increasing atmospheric CO 2 on plants and ecosystems and, in the long run, to contribute to the evaluation of terrestrial plant feedback regulation on the rate of change in CO 2 in the atmosphere as discussed by the authors.

TL;DR: In this article, a field study was conducted at Maricopa, AZ, where wheat was planted from September to May over a 2-yr period for a total of 12 planting dates.

TL;DR: This field-scale study of wheat using free-air CO2 enrichment found little evidence of acclimatory loss of photosynthetic capacity with growth in elevated pCO2 and a significant and substantial increase in leaf photosynthesis throughout the life of the crop.

TL;DR: In this paper, the predictions of three daily time step wheat simulation models (AFRCWHEAT2, FASSET and Sirius) were tested against data from wheat (Triticum aestivum L.) experiments in AZ in which the amount of applied N and the atmospheric CO2 concentration were both varied.

TL;DR: In this paper, a 4-year research program was undertaken with wheat (Triticum aestivum L.) as a model system for forage grasses, to document the potential changes in leaf N concentration in response to global environment changes.
