Differential Flag Leaf and Ear Photosynthetic Performance Under Elevated (CO₂) Conditions During Grain Filling Period in Durum Wheat.

ABSTRACT: Elevated concentrations of CO₂ (CO₂) in plants with C₃ photosynthesis metabolism, such as wheat, stimulate photosynthetic rates. However, photosynthesis tends to decrease as a function of exposure to high (CO₂) due to down-regulation of the photosynthetic machinery, and this phenomenon is defined as photosynthetic acclimation. Considerable efforts are currently done to determine the effect of photosynthetic tissues, such us spike, in grain filling. There is good evidence that the contribution of ears to grain filling may be important not only under good agronomic conditions but also under high (CO₂). The main objective of this study was to compare photoassimilate production and energy metabolism between flag leaves and glumes as part o
