Differences among three populations of Pinus uliginosa and their relation to P. sylvestris as expressed by the needle characters

37-46

The results of morphological and anatomical studies on Pinus uliginosa needles from newly-discovered localities of this species in Węglowiec (Bory Dolnośląskie) are presented. The data obtained were compared to similar published material on P. uliginosa needles from its loco classico in Batorow and from the lowland locality in Węgliniec Nature Reserve, and to P. sylvestris growing nearby. In terms of needle structure, all three P. uliginosa populations were slightly different. The samples analyzed differed markedly from the sample of P. sylvestris, which contradicts the hypothesis that Scots pine has had a significant influence on the gene pool of P. uliginosa.
