Opis:
Over 50 populations of Norway spruce from Bavaria were analysed at 23 isozyme gene loci. The mean genetic distances between these populations were quite small. A geographical grouping could not be observed, and discrimination between provenances from high and low altitudes was not identifiable using this marker type, either. The only difference between spruce populations from South Bavaria and those from Northeast Bavaria is in the presence of some distinct rare alleles. The highest values for the genetic diversity were detected for spruce stands in Northeast Bavaria (Frankonian Forest). Using STS markers, further genes of the nuclear genome of Picea abies can be dealt with. The genetic differences found on the basis of ten STS markers between different Picea abies seed lots and/or seedling populations are generally 2-3 times greater than those found by means of isozyme gene markers. DNA markers turned out to be an appropriate and substantial addition or even more a suitable alternative to isozyme markers for analysing genetic variation and testing provenance identity. Their advantages consist in a markedly wider variation as well as in the enlarged genome segments investigated.

Opis:
Considered to be the most natural of all other Polish stands Picea abies in Białowieża Forest has suffered severely of bark beetle damages for decades. In order to find out some historical events in native Norway spruce stands diversity at regional level, we carried out the study on poly− morphism with DNA markers and performed Principal Coordinate Analysis (PCoA) on the basis of genetic distance matrix. Two ranges (i.e. Baltico−Nordic and Hercyno−Carpathian) of Norway spruce cover north−eastern and southern Poland, respectively. The spruceless zone separates the these two ranges in lowland Poland. From genetic point of view, the Baltico−Nordic P. abies populations mainly harbor mitochondrial haplotype ‘c', whereas the spruces from the Hercyno− −Carpathian range – haplotype ‘a'. Until recently, the Białowieża Forest has been considered to belong to the northern range of spruce occurrence in Europe. Seven populations from Biało− wieża Forest were studied (two of them from the Strict Reserve in Białowieski National Park) according to mitochondrial DNA diversity, and compared with genetic diversity found in 24 other populations located in Białystok Regional Directorate of the State Forests (north−eastern Poland). All studied spruce populations were more than 100 years old and were of natural origin. As result, the spruces from the Białowieża Forest harbored three mitochondrial haplotypes of the nad1 gene (‘c', ‘a' and ‘a1'), with the haplotype ‘a' being more frequently present (>51%) than the hap− lotype ‘c'. The spruce stands from Białowieża Forest have the highest gene diversity (h Nei=0.527) comparing to the other stands from the Białystok RDSF. The PCoA proved the particularity of the spruces from Białowieża Forest grouping them into one cluster of genetic similarity. Our data demonstrated that most of Norway spruces populations from Białystok RDSF harbor haplotype ‘c', which confirms their historical relationship with the Baltico−Nordic range of P. abies in Europe, while most spruces from Białowieża Forest have different historic origin, because they share high frequency of the southern haplotype ‘a'. It also turned out that Norway spruce pop− ulations from two different European ranges met in lowland Poland after the last glacial period, as proved by the presence of two mitochondrial haplotypes ‘a' and ‘c'. It can be assumed, that the spruceless zone was created by human activity in the past millennia. The results of all molecular analyses confirmed the unique character of spruces of Białowieża Forest, which is distinguished by the greater richness of the gene pool in comparison to the region of Białystok RDSF as well as good adaptation to local environmental conditions.

Opis:
The origin of the Norway spruce in the Kartuzy Forest District was verified using the maternally inherited mitochondrial DNA marker mt15−D02 that shows distinct geographical distribution in Europe. We analyzed 462 trees from 26 populations. The majority of trees were of Alpine origin and they were present in all populations at a frequency of 6−90% (mean 59%). About 30% of trees were of the Carpathian origin and the least abundant (11%) were trees of north−eastern origin. The trees carrying north−eastern type of the mitochondial DNA marker were found only in 13 populations, but at a very different frequency (from 5 to 88%). The possibility of natural origin of Norway spruce in the area of Kartuzy Forest District was shortly discussed.

Opis:
Mitochondrial DNA marker was applied to 10 populations of silver fir from Poland and one from Belarusia. These populations were located within and beyond the natural range of silver fir. The marker exhibited two highly conserved alleles (first – 230 bp and second – 150 bp) based on an insertion−deletion of 80 bp in the fourth intron of the mitochondrial nad5 gene. The geographical distribution of the maternally inherited mitochondrial variation is known to support the existence of at least two refugia with two recolonizing maternal lineages remaining largely separated throughout the range. Our results provide that in all studied populations the first allele was discovered. Therefore we postulate that the silver fir migrate to Poland from the refugium in western Europe (probably from central Italy).

Opis:
The natural stands of Norway spruce in Poland are split between the southern and the northeastern parts of the country. Two so-called "spruceless" zones separate the northern spruce locations from those in the south, one "spruceless" zone is situated in Central Poland, and the other one in the Beskid Mts. Mitochondrial (STS) and nuclear (SSR) markers were used to perform the genetic identification of Norway spruce. Four different variants of haplotypes, "a", "b", "c" and "d", were found to occur in the nad1 locus of STS markers. Populations from the northern range of Picea abies distribution in Poland harboured exclusively haplotypes "c" and "d", except for the Białowieża population which had haplotypes "a" and "c". Populations from the "spruceless" zones contained four types of haplotypes whilst those from southern Poland were mostly composed of haplotype "a". High mean gene diversity was observed for both STS and SSR markers (HT = 0.529, and HT = 0.851, respectively). The total genetic differentiation of Norway spruce populations was very low (FST= 0.088). Two main groups of populations were distinguished in the dendrogram defined by Nei's genetic distances based on microsatellite markers. The distribution of the genotypes was scattered and did not show any connection with the spatial distribution of P. abies in Poland. Only the mtDNA markers were able to differentiate the northern populations of Norway spruce from the southern ones, proving the historical separation between the Baltico-Nordic and the Hercyno-Carpathian ranges of P. abies in Poland. By contrast, the microsatellite data suggested an overlap between the genotypes due to the human manipulation of Norway spruce stands in the past.

Opis:
Origin of Norway spruce in the territory of Skrwilno Forest District was studied with the use of mitochondrial mt−D02 region inherited through maternal line. The former suppositions of Jedliński, who claimed that the origin of spruce in this territory was natural, have been confirmed. Concurrently, it has been established that in the majority of tree stands subject to our study there occurs spruce of Carpathian origin. The obtained results together with the palinological data indicate that the northern border of spruce range in Poland runs right through the territory of Skrwilno Forest District and not about 100 km to the south from this place as has been claimed so far.
