Bioclimatic influence on essential oil composition in South Iberian Peninsular populations of Thymus zygis / Rafael Pérez-Sánchez in The journal of essential oil research, Vol. 24 N° 1 (Fevrier 2012) 

Public ISBD [article]  in The journal of essential oil research > Vol. 24 N° 1 (Fevrier 2012) . - pp. 71-81 Titre : Bioclimatic influence on essential oil composition in South Iberian Peninsular populations of Thymus zygis Type de document : texte imprimé Auteurs : Rafael Pérez-Sánchez, Auteur ; Cándido Gálvez, Auteur ; José L. Ubera, Auteur Année de publication : 2012 Article en page(s) : pp. 71-81 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Thymus  zygis  Labiatae  Essential  oils  Variability  Bioclimatic  influence  Environmental  factors  Canonical  analysis Résumé : The variation in yield and essential oil composition of some plants of Thymus zygis was studied through their life cycle. The relationship between the concentration of the essential oils’ main compounds and the most frequently used bioclimatic indices was stated. Individual samples from seven populations growing wild in the South Iberian Peninsula were studied to assess the phenological variation of their oils. The samples showed a maximum yield at the flowering stage. The most representative compounds were selected, statistically analyzed and clustered in two groups, called thymol and γ-terpinene according to their behavior through the cycle of the plants studied.
