Abstract
Variations were studied of the activity and isoenzyme patterns of soluble peroxidase, catalase, catechol oxidase and superoxide dismutase, in needles of the Balkan endemic conifer Serbian spruce, Picea omorika (Panč.) Purkinye. The samples were collected from the natural habitat of the species, Mt. Tara. Seasonal changes were found to affect enzymatic activities and isoenzyme profiles. Total protein content was significantly lower in the summer than in other seasons. Several isoforms of peroxidase, catechol oxidase and superoxide dismutase (SOD), as well as two catalase isoenzymes were detected. The number of peroxidase isoenzymes was greatest during the vegetative season. Catalase and catechol oxidase peaked in summer and spring, respectively. Total SOD and Mn-SOD activities were significantly higher in the winter samples than the summer ones.
