摘要: ABSTRACTChemical composition and phytotoxicity of oregano, marjoram Thymus mastichina essential oils against Portulaca oleracea L., Lolium multiflorum Lam. Echinochloa crus-galli (L.) Beauv. has been investigated. Seventy-seven compounds reaching 97.3% 99.4% were identified by gas chromatography–mass spectrometry. Carvacrol (60.42 ± 0.07%), p-cymene (15.52 ± 0.02%) γ-terpinene (5.19 ± 0.02%) the main in oregano oil, whereas large amounts 1,8-cineol (59.59 ± 0.85%, 49.49 ± 0.37%), linalool (13.05 ± 0.04%, 5.66 ± 0.01%) α-terpineol (3.36 ± 0.10%, 5.59 ± 0.01%), followed β-pinene (4.35 ± 0.39, 5.54 ± 0.01%) α-pinene (4.11 ± 0.53, 4.28 ± 0.01%) found, respectively, T. oils. Oregano oil completely inhibited seed germination seedling growth at all concentrations assayed (0.125–1 µL mL−1), only showed significant effects hypocotyl and/or hypocotyl + r...
