Abstract

Leucanthemum maximum 'Silver Princess' plants, that were gradually acclimated for 7 days at 10°C followed by 28 days at 7°C, were subjected to the following cold treatments: 30 days at 4°C; 4 or 5 days at 0°C and for 3 hours at -1°C to identify cold inducible proteins that may be responsible for cold tolerance in this cold tolerant species. Change in antioxidant enzymes activity in fully expanded leaves was assessed after each treatment. Catalase activity began to increase after 30 days at 4°C and reached its peak after a 5-day exposure to 0°C. The activity of cellular glutathione peroxidase and glutathione reductase significantly increased after a 4-day exposure to 0°C. Changes in activity of four active superoxide dismutase isoforms, one basic guaiacol peroxidase and two o-dianisine peroxidase isoforms were also detected following the full series of cold treatments (30 days at 4°C; 4 or 5 days at 0°C and for 3 hours at -1°C).
