Differentiation of fruiting and non-fruiting pimenta dioica (L.) merr. trees based on composition of leaf volatiles / Donna A. Minott in The journal of essential oil research, Vol. 19 N°4 (Juillet/Août 2007) 

Public ISBD [article]  in The journal of essential oil research > Vol. 19 N°4 (Juillet/Août 2007) . - pp. 354-357 Titre : Differentiation of fruiting and non-fruiting pimenta dioica (L.) merr. trees based on composition of leaf volatiles Type de document : texte imprimé Auteurs : Donna A. Minott, Auteur ; Heather A. Brown, Auteur Année de publication : 2007 Article en page(s) : pp. 354-357 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Pimenta  dioica  Myrtaceae  Pimento  Allspice  Essential  oil  composition  Eugenol  Fruiting  and  non-fruiting  trees  Male  and  female  trees Résumé : Leaf oil from fruiting female and non-fruiting male Pimenta dioica (L.) Merr. trees, were analyzed by GC. Oil yields from male pimento trees (2.13%) were typically lower than that for female trees (2.67%). Non-fruiting and fruiting trees contained the same volatile components with different relative abundances. The composition of eugenol (p< 0.01), and myrcene, α-phellandrene, γ- terpinene, terpinolene and α-thujene (p< 0.005) were significantly different in the female versus the male pimento trees. Characteristic monoterpenoid profiles were observed for the fruiting and non-fruiting pimento trees which could be used for the early prediction of the berry bearing ability of pimento trees.
