Nitrogen (N) input into food production is environmentally sensitive and economically significant, making efficient N use an important goal in agricultural practice and in plant breeding. In cereals, grain N concentration [N] is an important component of grain quality and nutritional value. Increasing atmospheric CO2 concentration [CO2] will not only stimulate growth and yield but also diminish grain [N], raising concerns about product quality and nutritional value. In this study we investigated how differences in root structure and function and agronomic properties between two bread wheat (Triticum aestivum L.) cultivars affect N uptake and allocation to grains in a low rainfall environment..
