| dc.description.abstract | The composition of the essential oil of Eugenia dysenterica collected from wild populations in Senador Canedo (SC) and Campo Alegre de Goiás (CA), as well as from cultivated plants growing adjacently from seeds at the same sites has indicated the presence of two oil clusters related to sampling origin. Cluster I included only SC samples, either from the cultivated population (subcluster IA) with high percentages of a-pinene (5.9-13%), b-pinene (6.6-14%) and (Z)‑b‑ocimene (0-13%), or from the wild population (subcluster IB) with high contents of g-cadinene (21-34%), limonene (1.3-28%) and caryophyllene oxide (1.5-14%). In cluster II, which included wild and cultivated samples originating from CA seeds, the major constituents were b-caryophyllene (15-44%), d-cadinene (6.4-21%) and a-copaene (4.4-14%). The canonical correlation revealed that limonene, g-cadinene, caryophyllene oxide, Zn, Cu, Fe, Mn, and mean monthly temperature and precipitation values were quite strongly related to SC wild samples (subcluster IB), whereas (Z)-b-ocimene, a-copaene, b-caryophyllene, a-humulene, d-cadinene, and P were related to CA wild samples as well as to all cultivated samples regardless of seed origin. The chemovariation might be genetically determined. In addition, SC samples showed a clear environmental influence. | pt_BR |
| dc.description.resumo | A composição dos óleos essenciais de Eugenia dysenterica de populações silvestres de Senador Canedo (SC) e Campo Alegre de Goiás (CA) e de plantas cultivadas, crescidas adjacentemente a partir de sementes dos dois sítios de amostragem, indicou a presença de dois grupos de óleos relacionados à origem das amostras. O grupo I incluiu amostras de SC, seja da população cultivada (subgrupo IA), com percentagens elevadas de a-pineno (5,9-13%), b-pineno (6,6-14%) e (Z)‑b‑ocimeno (0-13%), seja da silvestre (subgrupo IB), com percentagens elevadas de g-cadineno (21-34%), limoneno (1,3-28%) e óxido de cariofileno (1,5-14%). O grupo II incluiu amostras cultivadas e silvestres de CA, com b-cariofileno (15-44%), d-cadineno (6,4-21%) e a-copaeno (4,4-14%) como majoritários. A correlação canônica revelou que limoneno, g-cadineno, óxido de cariofileno, Zn, Cu, Fe, Mn, temperatura e precipitação média mensal correlacionaram-se às amostras silvestres de SC, enquanto (Z)-b-ocimeno, a-copaeno, b-cariofileno, a-humuleno, d-cadineno e P correlacionaram-se às amostras silvestres de CA e a todas as amostras cultivadas, independentemente da origem da semente. As variações nos óleos parecem ser geneticamente determinadas, em adição a uma influência ambiental sobre as amostras de SC. | pt_BR |
