Essential oil content and composition, nutrient and mycorrhizal status of some aromatic and medicinal plants of Northern Greece

Abstract

A field survey was conducted in three northern Greek mountain areas (Chortiatis, Ossa, and Pieria) to investigate the mycorrhizal and nutritional status, and the essential oil content and composition of common medicinal and aromatic plants. A range of values for nutrient status and essential oil contents and composition was established. All plants were found to be mycorrhizal, including Achillea coarctata Poir., Micromeria juliana (L.) Bentham ex Reichenb., and Salvia sclarea L.;. these three are reported as being mycorrhizal for the first time. Arbuscular mycorrhizal fungal root colonization was highest in Pieria, exceeding 80% for all 15 plants sampled, and lower in Chortiatis and Ossa.
