Resumo: | This paper aimed to evaluate the allelopathic potential of ethanol extracts from stem and leaves of Copaifera sabulicola on seed germination and seedling growth of Lactuca sativa and Lycopersicum esculentum, as well as to evaluate the allelopathic effect of these extracts on seedling germination and growth of Zea mays, through bioassays under laboratory conditions. The extracts were tested at the concentrations 0, 250, 500, and 1,000 mg.L-1. We evaluated the germination percentage, germination average speed, germination speed index, and seedling average length. All parameters underwent variance analysis, and the mean values were compared by means of Scott-Knott test (p ≤ 0.05). We found out that, in L. sativa, the extract from stem promoted significant stimuli on germination percentage and root growth, while the extract from leaves only stimulated root growth. In L. esculentum, the extract from stem promoted significant stimulus on hypocotyl and root growth, in turn, the extract from leaves stimulated only root growth. In Z. mays, both extracts significantly inhibited germination. Therefore, we found out the allelopathic potential of ethanol extracts of C. sabulicola on L. sativa and L. esculentum, as well as inhibitory allelopathic effect on Z. mays. |

Os extratos foram testados nas concentrações 0, 250, 500 e 1.000 mg.L-1. Avaliou-se a porcentagem de germinação, velocidade média de germinação, índice de velocidade de germinação e comprimento médio das plântulas. Todos os parâmetros foram submetidos à análise de variância, sendo as médias comparadas pelo teste Scott-Knott (p ≤ 0,05). Verificou-se que, em L. sativa, o extrato do caule promoveu estímulos significativos na porcentagem de germinação e no crescimento radicular, enquanto o extrato foliar estimulou somente o crescimento radicular. Em L. esculentum, o extrato do caule promoveu estímulos significativos no crescimento do hipocótilo e radicular, já o extrato foliar estimulou somente o crescimento radicular. Em Z. mays, ambos os extratos inibiram significativamente a germinação. Portanto, constatou-se o potencial alelopático dos extratos etanólicos de C. sabulicola sobre L. sativa e L. esculentum, bem como o efeito alelopático inibitório sobre Z. mays.Universidade Federal de Santa Catarina2014-05-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2014v27n3p2310.5007/2175-7925.2014v27n3p23Biotemas; v. 27 n. 3 (2014); 23-322175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2014v27n3p23/27637Copyright (c) 2014 Manoel Viana Linhares Neto, Rafael Soares Pozzi Malheiros, Farley Silva Santana, Luciana Lucas Machado, Ana Maria Mapeliinfo:eu-repo/semantics/openAccessLinhares Neto, Manoel VianaMalheiros, Rafael Soares PozziSantana, Farley SilvaMachado, Luciana LucasMapeli, Ana Maria2017-10-19T18:39:49Zoai:periodicos.ufsc.br:article/29406Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2017-10-19T18:39:49Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
