Resumo: | With the advance of agriculture, there was consequent rising in environment degradation. Therefore, It is interesting the use of plants which have in their chemical composition substances capable of helping in the control of weeds to minimize the use of pesticides. Hence, the objective of this paper was to evaluate solutions of leucena extract on weeds that are frequent on soybean crop. The treatments were leucena extracts at 0, 20, 40, 60, 80 and 100% at room temperature water and water heated to 80°C. The extracts were obtained by crushing 200g of leucena leaves and mixing them with one liter of distilled water with the help of a blender. Seeds were kept in B.O.D. at a temperature of 25°C, with a photoperiod of 12 hours of light. Evaluations were done on a daily basis, from the first to the last day of the experiment, varying according to the species. Results show a negative interference of the extracts, both hot and cold, in the root length of Ipomoea grandifolia, in the percentage of germination and in the root length of Arrowleaf sida and Hair beggarticks. There was no negative interference in the analyzed parameters for soybean seeds. Thus, the results indicate allelopatic potential of Leucaena leuucocephala as an alternative for the management of weeds without interfering on the development of the soybean crop. |

Assim, estuda-se a utilização de plantas que possuam em sua composição química substâncias capazes de auxiliar no controle de plantas invasoras, amenizando o uso de agrotóxicos. Desta forma, o objetivo do trabalho foi avaliar soluções de extratos de leucena sobre plantas invasoras que freqüentemente ocorrem na cultura da soja. Foram utilizados como tratamentos os seguintes extratos de leucena nas proporções de: 0, 20, 40, 60, 80 e 100% com água à temperatura ambiente e com água aquecida à 80°C. Os extratos foram obtidos triturando-se 200 g de folhas de leucena em um litro de água destilada, com auxílio de um liquidificador. As sementes foram mantidas em B.O.D. à temperatura de 25°C, com fotoperíodo de 12 horas de luz. As avaliações foram diárias, do primeiro ao último dia de experimento, este variando conforme a espécie. Os resultados demonstraram interferência negativa dos extratos, tanto quente quanto frio, no comprimento de raiz de corda de viola, na porcentagem de germinação e no comprimento de raiz de guanxuma e picão-preto. Não foram constatadas interferências negativas nos parâmetros analisados para as sementes de soja. Sendo assim, os resultados obtidos indicam potencial alelopático da espécie Leucaena leuucocephala como alternativa de manejo de plantas invasoras sem interferir no desenvolvimento da cultura da soja.UEL2009-07-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/262310.5433/1679-0359.2009v30n1p55Semina: Ciências Agrárias; Vol. 30 No. 1 (2009); 55-62Semina: Ciências Agrárias; v. 30 n. 1 (2009); 55-621679-03591676-546Xreponame:Semina.
