Other claims from this paper (11)

Intervention effect CO2 enrichment stimulated total dry matter productivity, maximum shoot number and final ear number at both temperature and N levels.
Intervention effect At high N, CO2 enrichment stimulated total crop dry mass by 12 percent.
Association At high N, there was no significant interaction between CO2 and temperature on grain yield.
Intervention effect Warmer temperature had a direct negative effect on yield at both N and CO2 levels.
Intervention effect At high N, grain set was reduced at ambient +4°C temperature.
Intervention effect The overall negative effect of warmer temperature was greater on grain number (37 percent) than on yield.
Intervention effect The negative effect of warmer temperature on yield was 18 percent.
Association Warmer temperature was associated with a compensating increase in average grain mass.
Intervention effect At low N, elevated CO2 significantly decreased grain yield under ambient temperature.
Mechanism Early vegetative growth stimulated by CO2 may reduce the N available later for grain formation and filling.
Mechanism Shortening of the phenological stages may reduce the time available for accumulating resources for grain formation.
