摘要

Species with a wide geographic distribution constitute an ideal model system for characterizing the adaptation of secondary chemistry to local climate and testing the generality of hypotheses about how investments in secondary chemistry scale with relative carbon and nutrient availability. We studied needle carbon (CM), nitrogen (NM) and terpenoid contents per dry mass in Pinus sylvestris collected across a broad geographical (38° to 59° N, latitudes 18° to 29° E; Estonia, Sweden, Romania, Turkey) and altitudinal (26-1980) range. In the Turkish samples, a low CM value corresponded to the lowest levels of mono- and sesquiterpenoids. In addition, the Turkish pine needles lacked diterpenoids. The monoterpenoid profiles revealed the presence of two distinct pine chemotypes: the Turkish pines were characterized as ‘(−)-α-pinene pines’, while the Estonian, Swedish, and Romanian samples were identified as ‘(+)-α-pinene - (+)-3-carene pines’. Overall, Northern pine populations were characterized by higher foliage C and terpenoid contents and greater terpenoid diversity. In addition, the direct correlations of foliage C and terpenoid contents were observed for ‘(+)-α-pinene - (+)-3-carene pines’. Our study highlights major variations in composition and content of Scots pine needle terpenoids among geographically distinct populations.
