    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:
    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.

    Opis:
    The origin of the Norway spruce in the Gołdap Forest District from the north−eastern part of Poland was verified using the maternally inherited mitochondrial marker mt15−D02, which in Poland displays a geo−graphical specifity. We analyzed 730 trees from 29 populations and 21 plus trees. These populations included four reserves, four registered seed stand and 21 managed tree−stands. As a result of the performed analyses it was found that 8 out of 21 plus trees were non−native. Also 11 out of the 29 investigated pop−ulations contained trees of non−native origin. The scale of this phenomenon varies, although it encom−passes the entire region of the forest district.

    Opis:
    Field elm (Ulmus minor Mill.) is distributed mainly across central and southern Europe. In Poland this species occurs in the lowlands and foothills, where it grows mainly in the floodplain forests along the rivers. U. minor exists in a variety of climatic and ecological conditions. It is capable to tolerate floods as well as drought. Currently, most populations of U. minor are small and fragmented resulting from human activity and Dutch elm disease. Moreover, in the natural field elm populations, vegetative propagation by root suckers or sprouting can be observed. All these factors may affect the level of genetic variation of U. minor populations in Poland. In the present study, we determined the level of genetic variation and the clonal diversity of twelve natural U. minor populations in Poland (407 individuals) using eight nuclear microsatellite loci. The obtained results indicate that the studied field elm populations are characterized by low level of genetic variation (He=0.382; Ho=0.555; A=7.0). Additionally, the high level of clonality in field elm populations was estimated. The clonality level of examined elm populations varied among them, and in some cases was very high. Out of the 407 individuals analysed for clonal structure only 61 multilocus genotypes were identified. Furthermore, only one genotype was identified in the three study populations of field elm, which means that in each of these populations all trees belong to one genet. The values of genotypic richness (R) were heterogeneous among populations, with mean 0.148. The knowledge on the genetic diversity and the clonal structure of U. minor populations is essential to make future decisions regarding conservation of genetic resources of this species in Poland.
