n this paper the authors presents the influence of some aminoacids on the peroxidase and catalase activity in Fusarium graminearum (telemorphe - Gibberella zeae) parasite an wheat. In laboratory the fungus was cultivated on Brown media (without asparagine), in which was added 1g from the following aminoacids: glutamic acid, serine, methionine, leucine, histidine, lysine, valine, alanine, asparagine, arginine; it was also used a control without aminoacids. The of peroxidase and catalase activity was determined from mycelium and culture liquid at 21 days and 28 days after the inoculation was inffluenced by culture age and by the type of aminoacid from the culture media.
