As the atmospheric CO2 concentration increases, it is likely that wheat plants will begin to reap benefits from this phenomenon almost immediately after seedling emergence. Rising CO2 levels should increase cell division and elongation, thus spurring leaf expansion and biomass production to a greater degree than what is occurring under today's ambient CO2 concentration. Thus, it is likely that these collective responses will result in larger plants, which should also produce greater harvestable yields, as the CO2 content of the air continues to rise.
