The enzymatic systems have been investigated in individual trees derived from 17 distant localities in Europe and Asia. Esterase and glutamate dehydrogenase polymorphism was determined in extracts from mixture of 50 macrogametophytes, iperoxidase polymorphism was investigated in needle extracts from 3-month-old seedlings. While testing by disc electrophoresis needle extracts of Scots pine deriving from specimens of different geographic ranges it was found that those from the South displayed mare isoperoxidases than those from the North. Most pronounced differences in number and relative activity of esterase and glutamate dehydrogenase isozymes were found in the specimens originating from isolated stands. It is suggested that hight temperatures and dry summer periods could influence the number and activity of the isozymes
