Interactive effects of elevated CO2 concentration, drought and nitrogen nutrition on yield and grain quality of winter wheat

Popis výsledku v původním jazyce

Elevated CO2 concentration generally leads to increased rates of photosynthesis, increased formation of assimilates and finally to storing them in the grain. Increased storage of starch in the grain, however, leads to an unbalanced proportion to the proteins, and their absolute quantity decreases. This is particularly apparent in the conditions of nitrogen deficiency. Interaction effect of elevated CO2, nitrogen nutrition and drought are not yet sufficiently described. Within the manipulation experimentin open top chambers (Domaninek near Bystrice nad Pernstejnem) that allow simulation of elevated concentration of CO2 (expected by the end of this century - 700 mu mol mol(-1)) and simulation of drought periods, the effect of these interactions on biomass production, grain yield, protein content, and other quality parameters of grain was studied. Elevated CO2 concentration increased production of both aboveground biomass and grain. This stimulatory effect is more pronounced if nitrogen
