TL;DR: The varietal differences in the concentrations ofgrain N and minerals were fairly stable across the levels of N and preanthesis water supply, and the varieties that differed most in the grain N and P concentrations had almost the same endosperm/germ dry weight ratio.

TL;DR: It is hypothesized that a sufficient supply of carbon skeletons for ammonium assimilation in the roots is required for maximum growth under high ammonium concentrations, and that there is genotypic variability in this physiological trait.

TL;DR: HS was superior in shoot and root DM, total root length and root surface area, ammonium and nitrate uptake and shoot nitrogen concentration, irrespective of pH level, which indicates that, also under field conditions, mixed ammonium or nitrate fertilization is only beneficial to plant growth if both N forms are evenly distributed in the soil.

TL;DR: Concentrations of protein and minerals were positively correlated, suggesting that breeding for elevated levels of protein is likely to increase the concentrations of minerals.
