Effect of Fusarium infection on the content of selected polysaccharides in barley grain

Popis výsledku v původním jazyce

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
