e2“There was an increase in Fe concentration in soybean under medium N and wet conditions but nonsignificant. The reductions in protein concentrations for wheat and rice were ~5%–10%, and the reductions in Zn and Fe concentrations were ~3%–12%”
e1“Grain protein, Zn, and Fe concentrations were reduced under e[CO 2 ]; however, the responses of protein, Zn, and Fe concentrations to e[CO 2 ] were modified by water stress and N”
e6“compared to ambient [CO 2 ] (a[CO 2 ]) concentration”
