Resumo: The objective of this work was to identify allelopathic effects of volatile extracts of essential oils on germination and radicle length of lettuce seedlings. Five concentrations were utilized for each oil (0.0, 0.001, 0.01, 0.1 and 1.0%, v/v) arranged into a completely randomized design with four replicates of 25 seeds. The volatile extracts of essential oils of cinnamon, alecrim-pimenta, capim-citronela and alfavaca-cravo revealed allelopathic potentialities on lettuce seed germination and radicle growth, effect which varied according to the oil concentration. The volatile extract of Jaborandi essential oil stimulates radicle growth and does not inhibit lettuce seeds germination, which is characterized as a beneficial allelopathic effect.

Foram utilizadas cinco concentrações de cada óleo (0,0, 0,001, 0,01, 0,1 e 1,0%, v/v), em delineamento inteiramente casualizado, com quatro repetições de 25 sementes de alface. Os extratos voláteis de óleos essenciais de canela, alecrim-pimenta, capim-citronela e alfavaca-cravo evidenciaram potencialidades alelopáticas na germinação e comprimento das raízes de plântulas de alface, efeitos que variaram de acordo com a concentração do óleo. O extrato volátil de óleo de jaborandi estimula o crescimento da radícula e não provoca inibição da germinação de sementes de alface, caracterizando-se como de efeito alelopático benéfico.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAlves, Maria da Conceição SampaioFilho, Sebastião MedeirosInnecco, RenatoTorres, Salvador Barros2004-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6880Pesquisa Agropecuaria Brasileira; v.39, n.11, nov. 2004; 1083-1086Pesquisa Agropecuária Brasileira; v.39, n.11, nov. 2004; 1083-10861678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6880/3936info:eu-repo/semantics/openAccess2014-09-01T19:49:25Zoai:ojs.seer.sct.embrapa.br:article/6880Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-01T19:49:25Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
