Abstract
Grain samples of spring barley from the 2009 and 2010 harvest were analysed for the content of DNA of Fusarium species and Fusarium toxins (type B trichothecenes). Samples originated from different fields in Radzików, Central Poland. Qualitative and quantitative determination of Fusarium species in the grain was performed using a real-time PCR. Fusarium toxins in the grain were analysed by gas chromatography. Seven Fusarium species were detected in barley grain. The dominating species were F. avenaceum, F. graminearum and F. poae. The presence of F. culmorum, F. langsethiae, F. sporotrichioides and F. tricinctum was also detected. The concentration of trichothecene toxins in grain (deoxynivalenol, nivalenol) was low. The highest correlation coefficient of deoxynivalenol vs. Fusarium DNA was found for F. graminearum. Regarding nivalenol, the highest correlation coefficient was with F. poae DNA.
