Resumo: In the present study we evaluated the chemical composition and allelopathic activity of the essential oil (EO) of Blepharocalyx salicifolius (Kunth) O. Berg leaves on the germination and initial growth of Lactuca sativa L. (dicotyledonous) and Sorghum bicolor (L.) Moench (monocotyledon). EO was obtained by hydrodistillation for 3 h. The EO composition analysis was performed by gas chromatography coupled to a mass spectrometry (GC-MS). The allelopathic activity of EO was evaluated at 2.5; 5.0 and 7.5%. The seeds were immersed in the solution for 2 min., distributed in Petri dishes, that were maintained in a BOD incubator. On the seventh day, the variables germination (%), root length (cm), shoot length (cm) and total seedling length (cm) were evaluated. The major constituents identified in the OE were eucalyptol (49.6%), limonene (13.6%) and β-caryophyllene (12.2%). The EO affected negatively the germination percentage of L. sativa seeds and the root system and total seedling length of S. bicolor. There was a negative allelopathic activity against the two evaluated species.

Berg sobre a germinação e crescimento inicial de plântulas de Lactuca sativa L. (dicotiledônea) e de Sorghum bicolor (L.) Moench (monocotiledônea). O OE foi obtido por meio de hidrodestilação por 3 h. A análise da composição do OE foi feita por cromatografia gasosa acoplada a um espectrômetro de massas (CG-EM). A atividade alelopática do extrativo foi avaliada nas concentrações de 2,5; 5,0 e 7,5%. As sementes foram imersas nas soluções por 2 min e então foram distribuídas em placas de Petri. As placas foram mantidas em câmara incubadora BOD. No sétimo dia, foram avaliadas as variáveis germinação (%) e comprimento de raízes (cm), da parte aérea (cm) e total da plântula (cm). Os constituintes majoritários identificados no OE foram eucaliptol (49,6%), limoneno (13,6%) e β-cariofileno (12,2%). O OE afetou negativamente a porcentagem de germinação das sementes de L. sativa e os parâmetros sistema radicular e plântula total de S. bicolor. A atividade alelopática do OE foi negativa para as duas espécies avaliadas.Embrapa Florestas2021-12-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/204210.4336/2021.pfb.41e201902042Pesquisa Florestal Brasileira; v. 41 (2021)Pesquisa Florestal Brasileira; Vol. 41 (2021)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/2042/1650Copyright (c) 2021 Bruno Silva de Oliveira, Carlos Garrido Pinheiro, Nadia Helena Bianchini, Bibiana Fontana Batista, Alana Silveira Pavlack, Berta Maria Heinzmannhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessde Oliveira, Bruno SilvaPinheiro, Carlos GarridoBianchini, Nadia HelenaBatista, Bibiana FontanaPavlack, Alana SilveiraHeinzmann, Berta Maria2021-11-18T11:01:58Zoai:pfb.cnpf.embrapa.br/pfb:article/2042Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2021-11-18T11:01:58Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
