Chemosystematic studies in the genus Pinus . III. The leaf oil terpene composition of lodgepole pine from the Yukon Territory

The leaf terpenes of 95 lodgepole pines from the Yukon and Northwest Territories, as well as those of 30 typical shore pines from more southerly locations, were analyzed by gas–liquid chromatography. The terpene patterns of the northern trees were compared with the known patterns of lodgepole pine f...

Description
Summary:The leaf terpenes of 95 lodgepole pines from the Yukon and Northwest Territories, as well as those of 30 typical shore pines from more southerly locations, were analyzed by gas–liquid chromatography. The terpene patterns of the northern trees were compared with the known patterns of lodgepole pine from the Rocky Mountains (types B and C) and that of the shore pine (type A). Many trees from northern locations (including nunataqs that were refugia during the last ice age) had the type A terpene pattern of the shore pine and a few had the rare type C or intermediate (A–B, B–C) patterns. The implications for further lodgepole pine population studies by means of leaf oil terpenes analysis are discussed.
