Progression of the mycotoxin and nutrient concentration in wheat after inoculation with<Emphasis Type="Italic">Fusarium culmorum</Emphasis>

The aim of the study was to follow the mycotoxin formation and the changes in nutrient composition of wheat artificially inoculated withFusarium cuimorum. From anthesis until harvest, samples were taken once a week from the inoculated and control plots. The investigations were focused on the progression of the contamination of the wheat with deoxyni-valenol (DON) and zearalenone (ZON). Furthermore, the impact of the Fusarium inoculation on the quality parameters starch, crude protein, crude ash, viscosity, non starch polysaccharides (NSP) and thousand seed weight was examined. Deoxynivalenol was detected in higher concentrations and in earlier stages, while zearalenone was found later and in smaller amounts. Moreover, the infection withFusarium cuimorum had pronounced effects on some quality parameters.
