“…Indeed, environmental factors, such as geography, temperature, day length, and nutrients, have been examined and are thought to play a role in the chemical composition of EOs (Masotti, Juteau, Bessière, & Viano, 2003;Angioni, Barra, Coroneo, Dessi, & Cabras, 2006;Gardeli, Vassiliki, Athanasios, Kibouris, & Komaitis, 2008). These factors influence the biosynthetic pathways of the plant and, consequently, play a role in the relative proportions of the major characteristic compounds, leading to the existence of different chemotypes that distinguish EOs from different regions.…”
