We analyzed low molecular mass phenolics, lignin content and both soluble and cell wall bound peroxidase activity in the needles of three Picea omorika (Pancic) Purkyne lines grown in the generative seed orchard. The highest values of the total phenol content as well as of catechine, caffeic acid, coniferyl alcohol, isoferulic acid and lignin concentration were detected in B5 line ("semidichotomy" line). The soluble guaiacol peroxidase activity was the highest in A3 line (line "borealis"). The highest activity of cell wall bound peroxidases was measured in B5 line, and it was in correlation with lignin content.
