Resumo: | The alecrim-pimenta and the lemongrass produce secondary compounds that can be used in alternative management of weed. The objective of this work was to evaluate the allelopathic effect of the essential oils of alecrim-pimenta and lemongrass in germination of lettuce achenes. It was used mature leaves of both species, and extracted the essential oil by distillation method of drag by water vapor. The bioassay was performed using achenes of crisp-leaf lettuce for summer and arranged in factorial scheme 5 x 2, being five concentrations of 0, 0.25, 0.5, 0.75 and 1.0% and two species of medicinal plants. It was used four replicates of 50 achenes. The oil of lemongrass was more detrimental to the germination of lettuce achenes when compared with the oil of alecrim-pimenta, being this effect dependent of the concentration. Germination of lettuce achenes treated with lemongrass oil declined by 34%, 12% and 75% for concentrations of 0.25%, 0.75% and 1.0%, respectively when compared with alecrim-pimenta oil. The germination speed index, the length and dry weight of hypocotyl and radicle of lettuce seedlings was compromised by the contact of alecrim-pimenta and lemongrass oils. Although there were lettuce achenes germination treated with alecrim-pimenta oil, the percentage of abnormal seedlings was high, which compromises their survival in field. |

Objetivou-se com esse trabalho verificar o efeito alelopático dos óleos essenciais de alecrim-pimenta e capim-santo na geminação de aquênios de alface. Foram utilizadas folhas maduras de ambas as espécies, e extraído o óleo essencial pelo método de destilação de arraste por vapor de água. O bioensaio foi realizado utilizando aquênios de alface da cultivar crespa de verão e arranjado em esquema fatorial 5 x 2 sendo cinco concentrações 0, 0,25, 0,5, 0,75 e 1,0 % e duas espécies de plantas medicinais. Foram utilizadas 4 repetições com 50 aquênios. O óleo de capim-santo foi mais prejudicial à germinação de aquênios de alface, sendo esse efeito dependente da concentração. Houve redução de 34%, 12% e 75% da germinação de aquênios de alface tratados com o óleo de capim-santo nas concentrações de 0.25%, 0.75% e 1.0% respectivamente comparando-se ao óleo de alecrim pimenta. O índice de velocidade de germinação, o comprimento e a massa seca do hipocótilo e da radícula das plântulas de alface, foram comprometido pelo contato dos óleos de alecrim-pimenta e capim-santo com os aquênios do bioindicador. Embora tenha ocorrido à germinação dos aquênios de alface tratados com óleo de alecrim-pimenta a porcentagem de plântulas anormais foi elevada, o que compromete sua sobrevivência em campo.UEL2013-05-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/886710.5433/1679-0359.2013v34n2p485Semina: Ciências Agrárias; Vol. 34 No. 2 (2013); 485-496Semina: Ciências Agrárias; v. 34 n. 2 (2013); 485-4961679-03591676-546Xreponame:Semina.
