PRELIMINARY RESULTS ON ALLOZYME DIVERSITY AND DIFFERENTIATION OF NORW AY SPRUCE (PICEA ABIES (L.) KARST.) IN POLAND BASED ON PLUS TREE INVESTIGATIONS

摘要

Genetic diversity and genetic differentiation among Polish populations of Norway spruce (Picea abies (L.) Karst.) were studied analyzing allozyme variation at 24 loci. Presented investigations based on 81 clones represented 6 populations from three different regions: Sudety Mts., Beskid Mts. And North-East Poland. On average, the expected heterozygosity was 0.134, 52.8/100 of loci were polymorphic, and the number of alleles per locus was 1.8. Our data confirm the hypothesis that a lower level of variation of Picea abies exists in central Europe, compared to other regions of its natural distribution.
