The activities and isoenzyme profiles of superoxide dismutase (SOD) and in vitro Fritillaria meleagris bulbs in response to cold treatment (4 deg C) were investigated. Differences in SOD activity and isoenzyme profiles in bulb under standard growth conditions, six weeks chilling, as well as seven days after the completion of cold treatment. Four isoforms of SOD are active under standard and chilling conditions, while three isoforms are presented 7 days after cold treatment. Native gel electrophoresis indicated the presence of mitochondrial and chloroplast localized SODs.
