| Description
| - Infection of stands by fungi of the genus Fusarium leads to a decrease in yield and quality of barley grain due to the presence of mycotoxins, their toxic secondary metabolites. A set of 29 cultivars and genetic resources of spring barley, grown at two locations (Kroměříž, Žabčice) in 2011–2012 in an experiment with natural infection and inoculation with F. culmorum, was used to study the relationship between a level of infection and the content of selected polysaccharides (starch, fibre, beta-glucans). The results revealed that the inoculation was a significant factor of variability for beta-glucans only, the content of which reduced due to an increased infection pressure. Contents of examined trichothecenes and zearalenones in grain ranged from the limit of quantification (LOQ) to 22210 migrogrammes/kg (DON – deoxynivalenol; cv. Ricardo, inoculated variant) and were affected by both year and location. Significant negative correlations between DON-3G (deoxynivalenol-3-glucoside), DON and beta-glucan content in grain detected in groups of cultivars with covered grain, standard starch or 2-row spike were not confirmed in sets with opposite characters, i.e. naked caryopses, waxy starch or 6-row spikes. The results of the study correspond with the data that the differences in the level of Fusarium infection and mycotoxin accumulation in individual barley materials are influenced by morphological and vegetative specificities determined by the genotype rather than by differences in the content of basic components of grain.
