CO<sub>2</sub> Responses of Winter Wheat, Barley and Oat Cultivars under Optimum and Limited Irrigation
Field crop production must adapt to the challenges generated by the negative consequences of climate change. Yield loss caused by abiotic stresses could be counterbalanced by increasing atmospheric CO<sub>2</sub> concentration, but C<sub>3</sub> plant species and varieties ha...
