J. Szweykowski et al., THE GENETIC-STRUCTURE OF SCOTS PINE (PINUS-SYLVESTRIS L) POPULATION FROM THE TOP OF SZCZELINIEC-WIELKI MT, CENTRAL SUDETES, Acta Societatis Botanicorum Poloniae, 63(3-4), 1994, pp. 315-324
The comparison of the genetic stucture of the population of Scots pine
from Szczeliniec Wielki Mt. with the population of its progeny and th
ree other populations from the same geographic region shows great simi
larity of both populations as far as the frequencies of genes and geno
types are concerned. Also other genetic parameters, such as heterozygo
sity, genotypic poly morphism indices and a number of alleles per locu
s were in both populations very similar. It seems that our data proved
that the provenance trial experiments reflect rather closely the gene
tic structure of maternal populations. The fact that the population fr
om Szczeliniec Wielki and its ''replica'' are genetically most similar
to the geographically closest population from Bystrzyca Klodzka leads
to the conclusion, that these populations are of common origin. Thoug
h the relic character of the populations from Szczeliniec can not be e
xcluded. The morphological distinctness of the population from Szczeli
niec is caused by a modifying influence of environmental conditions.
