Activity and isoenzyme composition of superoxide dismutase in the apoplast and whole-needle extract of Picea omorika (Panč.) Purkyně, was studied. Total SOD activity of the soluble fraction of the needle extract exceeded markedly that of the apoplastic SOD. Several acidic and two slow-migrating basic isoforms were found in the whole extract. Extracellular SOD had an extremely acidic isoform. Using specific inhibitors, we identified Cu/Zn- and MnSOD forms in the total extract, but only MnSOD in the apoplast. The Feisoform was not present in a detectable amount
