AB  - The essential-oil variability in seven native populations belonging to different infraspecific taxa of Pinus nigra (ssp. nigra, var. gocensis, ssp. pallasiana, and var. banatica) growing wild in Serbia was analyzed. In the needles of 195 trees from seven populations, 58 essential-oil components were identified. The major components were -pinene (43.6%) and germacrene D (29.8%), comprising together 73.4% of the total oil composition. Based on the average chemical profile of the main terpene components (with contents  gt 5%), the studied populations were found to be the most similar to populations from central Italy and Greece (ssp. nigra). Cluster analysis showed the division of the populations into three principal groups: the first group consisted of PopulationsI, II, III, IV, and V (considered as ssp. nigra group), the second of PopulationVI (ssp. pallasiana group), and the third of PopulationVII, which had the most distinct oil composition (ssp. banatica group). The taxonomic implications of the essential-oil profiles of the investigated taxa of this very complex species are discussed.

AB  - This is the first report on the composition and variability of the needle-wax n-alkanes in natural populations of Pinus nigra in Serbia. Samples of 195 trees from seven populations belonging to several infraspecific taxa (ssp. nigra, var. gocensis, ssp. pallasiana, and var. banatica) were analyzed. In general, the size of the n-alkanes ranged from C16 to C33, with the exception of ssp. nigra, for which it ranged from C18 to C33. The most abundant were C23-, C25-, C27-, and C29-alkanes. The needle waxes of Populations IIII and V were characterized by a higher content of C23-, C25-, and C27-alkanes and a lower content of C24-, C26-, C28-, and C30-alkanes, compared to the other populations, and the trees of these populations could be assigned to ssp. nigra. The samples of Population VI were characterized by higher amounts of C22-, C24-, C30-, and C32-alkanes and lower amounts of C25- and C27-alkanes, and the trees could be considered as ssp. pallasiana. The samples of Population VII, consisting of trees belonging to var. banatica, were richer in C29-, C31-, and C33-alkanes. The wax compositions of Populations IV and V, both composed of trees previously determined as P. nigra var. gocensis, showed a tendency of splitting. Indeed, the alkane composition of Population IV was closer to that of ssp. pallasiana pines, while that of Population V was more similar to that of ssp. nigra pines. From the results presented here, it is obvious that in the central part of the Balkan Peninsula, significant diversification and differentiation of the populations of black pine exists, and these populations could be defined as different intraspecific taxa. Our results also indicate the validity of n-alkanes as chemotaxonomic characters within this aggregate.
