Elevated CO2 Increases Nitrogen Fixation at the Reproductive Phase Contributing to Various Yield Responses of Soybean Cultivars

Yansheng Li; Zhenhua Yu; Xiaobing Liu; et al. Frontiers in Plant Science 2017. doi:10.3389/fpls.2017.01546

Other claims from this paper (7)

Association Yield response to elevated CO2 correlated strongly with increased symbiotically fixed N between R5 and R8.
Intervention effect Elevated CO2 caused small increases in fertilizer-derived N uptake from R5 to R8.
Intervention effect Elevated CO2 caused small increases in soil-derived N uptake from R5 to R8.
Association Increases in fertilizer-derived and soil-derived N uptake did not correlate with enhanced yield.
Intervention effect Elevated CO2 reduced the proportion of seed N redistributed from shoots to seeds.
Association Total N uptake was associated with increased fixed N per nodule under elevated CO2.
Association Total N uptake was not associated with changes in nodule biomass, density or root length.
