| genetic differentiation of oak populations within the quercus robur/quercus petraea complex in central and eastern europe. | 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 s ... | 2001 | 11554972 |
