Species of the genus Fusarium and Fusarium toxins in the grain of winter and spring wheat in Poland
2021
The aim of the study was to determine the presence of Fusarium species and mycotoxins in wheat grain from harvest in 2009 and 2010 in Poland. Samples from different locations were analyzed for the content of DNA of Fusarium species and mycotoxins. In 2009, DNA of F. graminearum and F. poae was present in all samples, F. culmorum in 82% of samples, and F. avenaceum in 55% of samples. In 2010, the highest content of DNA was found for F. graminearum followed by F. avenaceum, F. poae and F. langsethiae. The amount of F. culmorum DNA was very low. The most frequently occurring species were F. poae and F. graminearum, however, the amount of F. poae DNA was lower. In 2009, deoxynivalenol was detected in all samples. In 2010, the average content of deoxynivalenol was lower than in 2009. Nivalenol was detected at very low concentration in both years. Significant correlations between content of F. graminearum DNA and deoxynivalenol concentration in the grain and between content of F. poae DNA and nivalenol concentration in the grain in 2009 were found.
