Abstract
Pink snow mould is a disease caused by Microdochium nivale affecting winter cereals and grasses. In response to pathogen attack, plants initiate oxygen burst within which hydrogen peroxide increases rapidly in a huge amount. We have investigated the activity of catalase (CAT), non-specific peroxidases (PX) and isoforms of superoxide dismutase (SOD) in leaves of grasses from complex Lolium-Festuca 2, 4 and 8 days after inoculation with M. nivale. Each plant species showed a specific pattern of enzymatic kinetics during infection. We concluded that increased activity of PX and decreased activity of CAT may be recognized as the markers of the M.nivale resistance.
