Gatunki z rodzaju Fusarium oraz toksyny fuzaryjne w ziarnie pszenicy ozimej i jarej w Polsce


Abstrakt

Celem badania było określenie obecności gatunków Fusarium i mykotoksyn występujących w ziarnie pszenicy w Polsce w latach 2009 i 2010. Próby ziarna pochodzące z różnych regionów Polski zostały przeanalizowane pod kątem zawartości DNA grzybów z rodzaju Fusarium oraz mykotoksyn. W 2009 roku DNA F. graminearum i F. poae było obecne we wszystkich próbach, F. culmorum w 82% prób, F. avenaceum w 55% próbek. W 2010 r. najwyższą zawartość DNA stwierdzono dla F. graminearum, a następnie F. avenaceum, F. poae i F. langsethiae. Ilość DNA F. culmorum była bardzo niska. Najczęściej występującymi gatunkami były F. poae i F. graminearum. Jednakże ilość DNA F. poae była niższa. W 2009 r. we wszystkich próbach wykryto deoksyniwalenol. W 2010 r. średnia zawartość deoksyniwalenolu była niższa niż w 2009 r. Niwalenol wykryto w bardzo niskim stężeniu w obu latach. Stwierdzono istotność korelacji między zawartością DNA F. graminearum a stężeniem deoksyniwalenolu w ziarnie oraz między zawartością DNA F. poae a stężeniem niwalenolu w ziarnie w 2009 r.
