Abstract

Summary
Two populations of registered European beech seed stands growing at altitudes of 273 m (Vrhovo) and 657 m (Kozarje) a.s.l. in the Gorjanci Mountains were genetically investigated at 16 polymorphic gene loci. A cline from minor to major allelic polymorphism was revealed at gene loci Aco-B, Idh-A and 6-Pgdh-A. The Kozarje population of beech had a slightly higher genetic multiplicity, a slightly higher effective number of alleles per locus (ν), higher observed heterozygosity (H_o) and a higher level of intrapopulation differentiation (δ_T). Statistically significant differences in the occurrence of alleles between populations were found at 5 of 16 loci. The average genetic distance of Gregorius (1974) was 6.1 %. European beech populations analyzed from different altitudes on Gorjanci Mountains appeared to be genetically differentiated.
