The composition of the cuticular n-alkanes isolated from the leaves of
nine populations of Juniperus deltoides R. P. Adams from continental and
coastal areas of the Balkan Peninsula was characterized by GC-FID and
GC/MS analyses. In the leaf waxes, 14 n-alkane homologues with
chain-lengths ranging from C22 to C35 were identified. n-Tritriacontane
(C33) was dominant in the waxes of all populations, but variations
between the populations in the contents of all n-alkanes were observed.
Several statistical methods (ANOVA, principal component, discriminant,
and cluster analyses) were used to investigate the diversity and
variability of the cuticular-leaf-n-alkane patterns of the nine J.
deltoides populations. This is the first report on the n-alkane
composition for this species. The multivariate statistical analyses
evidenced a high correlation of the leaf-n-alkane pattern with the
geographical distribution of the investigated samples, differentiating
the coastal from the continental populations of this taxon.
