Results of a karyological study of Juniperus communis L. populations under swamp and dry conditions are presented. The chromosome
number of J. communis are 2n = 22. Analysis of morphological chromosome parameters showed a similarity between karyotypes of both populations.
It is possible to identify one pair of asymmetric chromosomes (VIII pair); this chromosome pair is close to submetacentric type. Three pairs of chromosomes
(I, VII, VIII) have secondary constrictions. Other metacentric chromosomes form groups of five long (II-VI) and three short (IX-XI) pairs. Differences between
two populations in absolute chromosomal length are observed.
