(2003): Fusarium head blight reactions and accumulation of deoxynivalenol, moniliformin and zearalenone in wheat grains
Cereal Research Communications, 31, 407-414

Abstract:
Deoxynivalenol (DON), moniliformin (MON) and zearalenone (ZON) are the most important mycotoxins detected in Fusarium infected wheat grains in Austria. Our goal was to identify an evaluation method for Fusarium. head blight (FHB) symptoms, which is closely related to the toxin content in grains of artificially inoculated wheat genotypes. In total 108 wheat lines with varying FHB resistance were treated with F. culmorum (DON producer), F. avenaceum (MON producer) or F. graminearum (ZON producer). Several FHB evaluation methods were investigated and the data were correlated with the mycotoxin content of the grains. Data on the visual scores of the FHB development in the field, percentage of Fusarium damaged kernels and specific grain weight showed acceptable correlations with the DON content (r=0.75-0.81). MON contamination was closely related to the percentage of Fusarium. damaged kernels (r=0.70). No suitable method was identified to predict ZON concentrations. Only in grain samples of highly resistant genotypes consistently a low ZON content was measured.
