Аннотация
Changes in activities of the enzymes performing direct antioxidant functions were studied in 7–8-week-old plants Arabidopsis thaliana Heinh (L.) of Columbia (Col-0) ecotype. It was found that 5-day cold hardening at 2°C increased plant cold resistance to the subsequent stronger cooling. Under these conditions, the marked changes occurred in activities of superoxide dismutase and III type (guaiacol) peroxidses but not in that of catalase. The total peroxidase activity exceeded the catalase activity before cold hardening. Therefore, peroxidases are able to decompose more H2O2 than catalases and appear to make the dominant contribution to the protection from the cold damage.
