    Opis:
    The needles of 17 samples representing 15 populations of Pinus mugo Turra from the Alps, Apennines, Sudethians, Carpathians and Rhodopes were analysed in respect to 15 morphological and anatomical characters. The results of measurements were analysed statistically. The variation of the samples was generally not to large. Populations from the East Carpathians appeared different from all other examined. Two formed groups of analysed populations are separated mainly by thickness of epidermal cells, width/thickness of epidermal cell ratio, needle width and needle thickness. The differences between two groups of populations suggest their longer separation during Pleistocene.

    Pinus mugo
    Opis:
    Two year-old needles were collected from 57 individuals from the Tatra Mts. between Grześ and Wołowiec summits. The needles were analysed in respect to 16 morphological and anatomical traits. Data obtained were subject of multivariate statistical analyses. The most stable traits appear to be needle thickness/width ratio, needle thickness and width, and width of epidermal cells. The most variable traits include the distance between vascular bundles and Marcet's coefficient. Intrapopulational variation is low.

    Opis:
    The basic aim of the work was to widen the knowledge about variation of Pinus mugo in the Karkonosze (Giant) Mountains and verification of provenance of several, probably planted populations on that basis. Seven populations were sampled, four on hardly accessible precipices of glacial cirques as natural, and three on the topical, mostly plane or only slightly in clined parts of the mountains as potentially alien ones. The variation of the needles was biometrically analyzed in respect of 23 morphological and anatomical characters. Measurement data were subject of multivariate statistical analyses. Results call attention on rather continuous variability of P. mugo in the Karkonosze Mts. The differences among samples were found as relatively low and no direct connections have been detected between variation and provenance from precipices versus plane sites.

    Opis:
    The taxonomic position of the population of tree-like, mostly polycormic individuals of pines from the Mshana peat bog in the Gorgany Mountains (East Carpathians, Ukraine) has been studied on the basis of the morphological characteristics of cones and needles, and anatomical characteristics of the needles. These features have been compared with the surrounding Pinus mugo population as well as P. uliginosa, P. mugo, P. sylvestris and P. uncinata from natural populations of the taxa. Tree-like individuals were found to have the most similar needles to P. uliginosa, but most similar cone characteristics to P. mugo. It was concluded, that the tree-like population has a relic character and can present the trace of the early migration of P. uliginosa from the West and its hybridisation with P. mugo.

    Opis:
    The main aim of this study was to describe the variation between the populations of the dwarf mountain pine Pinus mugo Turra based on the morphological and anatomical traits of their needles, and to investigate the relationship between the observed variation and environmental conditions (altitude and substrate).Two-year-old needles were collected from 180 individuals of six populations of P. mugo growing in the Tatra Mts. Two populations were classified as dense, located at 1360–1450 m altitude, and the remaining four formed loose clusters and were situated at 1500–1650 m altitude. Four of the populations are growing on granite and two on a limestone substrate. The natural variation of 10 morpho-anatomical and 3 synthetic needle traits was measured. In addition to descriptive statistics, the analyses of variance (ANOVA) with a Tukey test and principal component analysis were computed. We also estimated Pearson correlation coefficients for the examined needle traits and altitude as well as substrate. Our results indicate that the P. mugo populations differ significantly with regard to the investigated traits for which the Trzydniowiański Wierch population was the most distinct. The observed pattern of variability is largely caused by differences in stomatal traits and these features are positive correlated with altitude. Additionally, populations growing on granite have larger values for most of the examined traits compared to populations growing on limestone.
