Abstract
An improved TLC method ofFusaria metabolites detection and quantitation has been elaborated. A total 92 isolates of Discolor sectionFusaria from cereals and potato have been examined from the point of view of cultures morphology and ability to produce characteristic mycotoxins. Low nutrient media (CLA, SNA) were found as suitable for production of uniform and typical macroconidia in studied cultures. All 26 isolates ofF. sambucinum Fuckel (=F.sulphureum, Schlecht) formed diacetoxyscirpenol in amount 20-1000 mg/kg and all 17.F. crookwellense Burgess N. & T. produced zearalenone (16-602 mg/kg).F. graminearum Schwabe produced: zearalenone 14/14 isolates, deoxynivalenol 11/14 isolates, both up to 77 mg/kg. Out of 26F. culmorum cultures originating from Poland 22 produced zearalenone up to 675 mg/kg, 17/26 3 acetyldeoxynivalenol up to 280 mg/kg and 16/26 deoxynivalenol up to 220 mg/kg. The difference in metabolism agrees with the difference in morphology of those species.
