Genetic variability of phenological forms in selected provenances of Norway spruce of IPTNS-IUFRO 1964/68 experiment test in Poland

摘要

Here, we present an analysis of genetic variability of early and late phenological forms of Norway spruce growing on international inventory test IPTNS-IUFRO 1964/68 in Krynica, Poland. The polymorphism of 7 isozyme systems encoded in 11 loci was characterized. Early and late flushing spruce had a similar genetic variability of the following parameters: the mean and effective number of alleles per locus and the observed and expected heterozygosity. In each year of the observation, there was a significant correlation between the time of vegetation start and the allele frequency of the locus B of leucine aminopeptidase {Lap-B) and the locus A of glutamate dehydrogenase (Gdh-A). The geographic variability in the loci Gdh-A, Mdh-B, and Shdh-A was also observed.
