    Opis:
    The differentiation among three populations of Pinus sylvestris of the Tatra National Park (TNP); Łysa Skała, Siwarowe Pańskie and Wielkie Koryciska has been investigated with regard to eight anatomical traits of needles. These populations were compared to a lowland population of Tuchola Forests. Five analyzed traits: the thickness of epidermis with cuticle, the mean of width of three epidermis cells, the width of needle cross-section, the height of a needle cross-section and the ratio of height to the width of a needle are characterized by a variation coefficient not exceeding 10%. Variation coefficients for the remaining traits: the number of resin canals, the distance between vascular bundles and a Marcet coefficient, range between 15.04 – 24.95%. The needles of the lowland population (Rzepiczna) turned out to be the widest as well as the thickest and with the biggest distance between vascular bundles. The Tatra populations of P. sylvestris have a considerably thicker cuticle together with epidermis compared with the lowland population of Tuchola Forests. None of the individual traits differentiate the populations which have already been regarded as distinct – Łysa Skała, found in the eastern part of the TNP and Wielkie Koryciska, from its western part. However, having carried out a discriminant analysis and Mahalanobis distances, the differentiation of the Tatra Scots pine in relation to its geographical location was reported. The individual character of P. sylvestris found in the eastern and western parts of the Tatra National Park might be a result of their different origin in the last glacial period.

    Opis:
    The aim of this study was to characterize the turfosa form of Pinus sylvestris from the Gazwa peat bog reserve in terms of 16 anatomical needle traits and to determine whether pines with a typical morphotype inhabiting the peat bog have been so successful thanks to hybridization with the unique tufosa ecotype. Investigations were conducted on three phenotypic groups of Scots pine growing in the peat bog. The first two groups consisted of 30 tufosa trees at the age of 117-217 years and 20 trees at the age of 30-85 years. The third group consisted of typical pines represented by 10 trees at the age of 20-55 years. In total 30 trees of typical pine, surrounding the peat bog, at the age of 100-150 years served as outgroup. Descriptive statistics, analysis of variance with the F test, Tukey's test, and a number of multivariate analyses were used to estimate differences between the studied groups of trees based on 16 anatomical needle characteristics. The old turfosa form from the Gazwa reserve proved to be a unique and relict peat bog pine, as it was shown by the differences in 10 analyzed needle traits in comparison to pine with a typical morphotype growing in the areas surrounding the peat bog. The young typical pines have adapted to conditions found in the peat bog owing to hybridization with the turfosa forms. The young turfosa trees differed from the old turfosa trees and also they have probably been of a hybrid origin. The old turfosa form from the Gazwa reserve is a threatened ecotype due to its hybridization with pines from the population surrounding the peat bog.
