Název v původním jazyce

Interactive effects of elevated CO2 concentration, nitrogen nutrition and UV-exclusion on yield, aboveground biomass and root development in winter wheat and spring barley.

Popis výsledku v původním jazyce

Within the manipulation experiment in open top chambers (Domanínek near Bystřice nad Pernštejnem) that allow simulation of elevated concentration of CO2 ([CO2]) (expected by the end of this century -- 700 mikro mol mol-1) and exclusion of solar UV radiation, the interactive effects of these environmental drivers together with nitrogen application were studied. Aboveground biomass at the time of harvest, grain yield and root area were studied in winter wheat (variety Bohemia) and spring barley (variety Bojos).From three replications of each treatment were the roots of four plants dug out from the soil and gently washed. Photos of roots taken using the digital camera were analysed by image processing software Image J (plugin SmartRoot). The result showedthat the elevation of [CO2] increased the above ground biomass and grain yield. High level of nitrogen increased the stimulatory effect of [CO2] on the above-ground biomass and grain yield. Also UV exclusion stimulated the effect of the
