    Opis:
    Cones of Pinus uliginosa from the "Torfowisko pod Węglińcem" reserve were tested biometrically, on the basis of 16 characters.The obtained data were statistically analysed.The cone scale width, the ratio of cone length/width and the maximal diameter of cone were the most stable, while the cone scale thickness and the ratio of cone scale length/thickness were the most variable of the cone characters.The intrapopulational differentiation was not big.The examined pine species has cones with characters which are intermediate between Pinus sylvestris, P. mugo and P. uncinata.

    Opis:
    Pinus uliginosa is an interesting taxon from the Pinus mugo complex with controversial systematic position andspecific characteristics, intermediate among P. mugo, P. uncinata and P. sylvestris. The peat-bog pine is rare andprotectedin Poland. All its’ known populations have a relict character andare slightly different from each other. The aim of the present study was comparison of the individuals from the Czarne Bagno of the “Torfowisko pod Zieleńcem” Nature Reserve (Sudetes), determined in the field on the basis of morphological characteristics as Pinus uliginosa, with four samples of this taxon from the northern limits of its range in PolandandGer - many andwith Pinus sylvestris, P. mugo and P. uncinata, to verify morphological andtaxonomic relations between them. The material collected from 30 individuals determined as P. uliginosa, was closest to populations of P. uliginosa from the Bory Dolnośląskie, andto P. mugo from the Tatra Mts., concerning the needle characters. The cone characteristics of P. uliginosa individuals from the Czarne Bagno appeared similar to all other of that taxon. In spite of that, the cone characters first of all differentiate P. uliginosa from P. sylvestris, P. mugo and P. uncinata. The combination of needle and cone morphological characters are a good tool to distinguish P. sylvestris, P. uncinata, P. mugo and P. uliginosa with a very high probability.

    genetic differentiation
    Opis:
    Genetic differences between two populations of P. uliginosa from Batorów and Węgliniec were assessed on the basis of 15 allozyme loci. The level of genetic differentiation between them was also compared with genetic differences among the three closely related pine taxa: P. uliginosa, P. sylvestris and P. mugo. A high level of genetic variation was found in both populations of P. uliginosa. The average (Na) and effective (Ne) numbers of alleles per locus amounted respectively to 2.47 and 1.50 in Węgliniec and to 2.67 and 1.52 in Batorów and the percentage of polymorphic loci was 80% and 87%, respectively. Close relationship between the three studied species were confirmed. The genetic differences between the two populations of P. uliginosa were substantial, as the Nei's genetic distance between the two populations (D = 0.040) was larger than between populations of P. sylvestris and between populations of P. mugo. The relatively high level of genetic differentiation between P. uliginosa populations may result from their isolation, small size and possibly different origin of these populations.

    Opis:
    Pinus sylvestris (Scots pine) and taxa from the P. mugo (mountain pine) complex hybridize in contact zones producing morphologically-intermediate fertile hybrids. However, the hybrid specimens sometimes express only the P. sylvestris phenotype. Such cryptic hybrids were detected among P. sylvestris and P. uliginosa in the western part of Błędne Skały in the Stołowe Mountains, where the pines grow on the tops of sandstone rocks and phenotypically resemble P. sylvestris, P. uliginosa, and P. mugo. Hybrids with the P. sylvestris phenotype could be potentially present in other relic populations of this species in these mountains. During the present study, the hybrids were identified only in the area of Błędne Skały based on chloroplast and mitochondrial markers, morphological differentiation of various needle and cone traits, and phenotype assessments of the trees during sampling. these hybrids included three cryptic hybrids of P. sylvestris × P. mugo with the P. sylvestris phenotype and one displaying the phenotype of P. uliginosa. The other populations analyzed represented Scots pine with no evidence of hybridization with P. uliginosa and/or P. mugo. Biometric data on the cone and needle morphology also suggest possible hybridization within the P. mugo complex on Błędne Skały. The results indicate that hybridization takes place in this population but not in neighboring populations despite the possible connection by pollen-mediated gene flow.
