ELECTROPHORETIC DIFFERENTIATION POSSIBILITIES WITHIN THE GENUS QUERCUS BY MEANS OF PROTEIN MONOMERS

Taxonomic differences within the genus Quercus were studied with SDS-p oroPAGE in the case of 207 Q. cerris, Q. petraea and Q. robur individu als and with LiDS-poroPAGE in 75 Q. cerris, Q. petraea, Q. pubescens, Q. robur and Q. rubra trees. In the present material, protein monomer patterns were suitable to differentiate among 3 oak species (Q. cerris , Q. robur, Q. rubra) while Q. petraea and Q. pubescens had identical polypeptide profiles. Neither of the applied method was appropriate fo r the identification of subspecies, ecotypes or forms. Differences and identities of banding patterns may be related with the sophisticated genetics of Quercus.
