Opis (eng)

"Many studies show the influence of the environment on terpene composition, but not many of them deal withthe terpene composition variability in correlation with environmental factors in Pinus. We chose two endemic species – P. heldreichii Christ. (Bosnian pine) and P. peuce Griseb. (Macedonian pine) – two relict and (sub)endemic species of the Balkan peninsula. They mainly form pure stands but can appear in mixed populations, most commonly with each other. These species belong to different subgenera and thus differ greatly, especially in needle anatomy. α-pinene, limonene and germacrene D predominated in Bosnian pine leaf oleoresins, while Macedonian pine oleoresin contained high amounts of α-pinene. Furthermore, there were three chemotypes present in Bosnian, and only one in Macedonian pine. Oleoresins of Bosnian pine did not show correlation with climate, however, its composition changed in response to geological substrate type. Macedonian pine oleoresin showed a high correlation with the climate but changed only a little in response to geological substrate type. The oleoresin profiles showed strong species-dependent composition and variability. However, sinceeach species expressed different responses to tested environmental conditions, it is important to take into consideration these variables when analyzing natural populations of the species.
