| Popis: | The variability of n -alkanes in the needle cuticular wax of Pinus heldreichii and P. peuce in two natural populations from the Scardo-Pindic mountains was investigated for the first time. Gas chromatography (GC) and gas chromatography/mass spectrometry (GC–MS) analyses of two-year-old needles were performed using an Agilent 7890A GC equipped with an inert 5975C XL EI/CI mass spectrometer detector (MSD) and a flame ionization detector (FID) connected by a capillary flow technology 2-way splitter with make-up. An HP-5MS capillary column was used. n -Alkanes ranged from C 19 to C 33 . In P. heldreichii the most abundant were C 23 , C 25 and C 27 (16.3, 15.6 and 12.8% on average, respectively), while in P. peuce they were C 29 , C 25 , and C 27 (16.5, 15.3 and 13.5% on average, resp.). Mid-chain and long-chain n -alkanes prevailed in both species. Principle component analysis (PCA) and Cluster analyses of five and six n -alkanes, respectively, showed divergence of the Scardo-Pindic populations from the Dinaric ones. |
