Resumo: | The long lasting residual effect of some auxin herbicides depends on soil characteristics and may cause phytotoxicity on subsequent crops. Picloram is one of the main herbicides used in pastures, presenting a long lasting residual effect in the soil. This study aimed at determining the physiological and morphological characteristics of common bean plants grown in soil contaminated with picloram, under greenhouse conditions. A complete randomized blocks design, with treatments consisting of picloram doses (0 g ha-1, 7.5 g ha-1, 15 g ha-1, 30 g ha-1, 60 g ha-1 and 120 g ha-1 a.i.), with five replications, was used. Urochloa brizantha was sown in pots, and its height and shoot fresh and dry matter were evaluated. In the same pots, Phaseolus vulgaris was sown as a bio-indicator of picloram, and the following characteristics were measured: plant height, fresh and dry matter, phytotoxicity, leaf area, number of leaves per plant, maximum photosynthetic efficiency and relative electron transport rate. The phytoremediation process occurs in soil with picloram residues (up to 30 g ha-1) when covered by U. brizantha for 150 days. The common bean plants show a good potential as biological indicator of the presence of picloram residues in the soil. |

O picloram é um dos principais herbicidas utilizados em pastagens, sendo que o mesmo apresenta período de meia-vida longo no solo. Objetivou-se avaliar, em casa-de-vegetação, as características fisiológicas e morfológicas de plantas de feijão cultivadas em solo contaminado com picloram. O delineamento utilizado foi em blocos ao acaso, sendo os tratamentos compostos pela aplicação de picloram (0 g ha-1; 7,5 g ha-1; 15 g ha-1; 30 g ha-1; 60 g ha-1; e 120 g ha-1 i.a.), com cinco repetições. Urochloa brizantha foi semeada em vasos, avaliando-se a sua altura e matéria fresca e seca da parte aérea. Nos mesmos vasos, semeou-se feijão (Phaseolus vulgaris), como bioindicador do picloram, sendo avaliados a altura das plantas, matéria fresca e seca, fitotoxicidade, área foliar, número de folhas por planta, eficiência fotossintética máxima e taxa relativa de transporte de elétrons. Resíduos de picloram no solo (até 30 g ha-1) são fitorremediados pelo cultivo de U. brizantha por 150 dias. As plantas de feijão apresentam bom potencial como indicador biológico da presença de resíduos de picloram no solo.Pesquisa Agropecuária Tropical2018-03-15T00:57:13Z2018-03-15T00:57:13Z2016-07info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf1983-4063http://dx.doi.org/10.1590/1983-40632016v4640169http://www.locus.ufv.br/handle/123456789/18255engvol. 46, n. 3, p. 276-283, July/Sept. 2016Franco, Miguel Henrique RosaLemos, Vinícius TeixeiraFrança, André CabralSchiavon, Nykolas CarvalhoAlbuquerque, Marco Túlio GomesAlecrim, Ademílson de OliveiraD'Antonino, Leonardoinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T06:15:07Zoai:locus.ufv.br:123456789/18255Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T06:15:07LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
