| Factor Function |
The major differences in oil composition between the two populations are the variation in the concentrations of T-cadinol and borneol. The differences can also be ascribed to the distinct climatic pattern of the two samples: Sannine is located in the Mount Lebanon chain of mountains and characterized by heavy precipitations and snow, while the Bekaa valley is shielded by this same chain of mountains, resulting in dry summers and cold winters with less humidity and precipitations.
