Аннотация: By means of electrophoresis followed by histochemical staining, water-soluble enzymes of megagametophytes and embryos of seeds collected from 42 trees in two natural populations of Picea obovata were studied. A detailed analysis of electrophoretic patterns of enzymes ADH, GDH, 6-PGD, IDH, MDH, LAP, EST, and GOT is presented. It is shown that the allozyme diversity of the enzymes assayed is coded for by at least 20 loci. Fine electrophoretic resolution was obtained for the products of 16 loci, four of them (Mdh-1, Mdh-2, Got-1, and Got-2) were monomorphic, while the remaining loci (Adh-1, Adh-2, 6-Pgd-2, 6-Pgd-3, Mdh-3, Idh-2, Lap-1, Lap-2, Est-1, Est-3, Got-3 and Gdh) appeared polymorphic. Segregation data confirms the monogenic inheritance of the allozyme variants revealed.
