摘要：
Genetic structure of 25 indigenous populations of sessile and pedunculate oaks (Quercus petraea and Q. robur), originating from three geographical regions: Slovakia, Bulgaria and the Republic Mari-El (Russia), was investigated using isozyme markers. Mean number of alleles per locus ranged between 1.8 and 2.6 in Q. robur populations and from 2.0 to 3.0 in Q. petraea populations, slightly higher expected heterozygosity values were found in Q. robur compared to Q. petraea. One locus, coding for a substrate-nonspecific dehydrogenase, differentiated the two species. The interspecific component of gene diversity was 46.7% at this locus, compared to 0.4-7.8% at the remaining loci.
