Variation in the abundance of 13C and biological nitrogen fixation in legume plants such as alfalfa (Medicago sativa L.) can be used in cultivar selection programs allowing a better understanding of the physiological processes related to water use, photosynthesis and biological nitrogen fixation and their interdependence. This would supply data for selection programs for the improvement of dry matter yield (DM), water use efficiency (WUE) and biomass quality. Thus evaluation of the plant under contrasting conditions becomes necessary, therefore in […]
