Resumo: Picloram is an herbicide that presents a high persistence in the soil and may severely harm crops in rotation and the environment. The phytoremediation of contaminated areas has been investigated in order to decrease the persistence and environmental impacts of this herbicide. This study aimed to evaluate the influence of the cultivation period of Urochloa brizantha cv. Piatã on the phytoremediation of soil contaminated with picloram. A randomized blocks design, with five replications, was used and treatments consisted of five cultivation periods (150, 210, 240, 270 and 300 days). It was concluded that U. brizantha acted effectively in the phytoremediation of contaminated soils, and the higher the cultivation period, higher was its phytoremediation potential. A recovery in the photosynthetic apparatus of the bioindicator plants (Phaseolus vulgaris) studied was observed after 240 days of U. brizantha cultivation.

A fitorremediação de áreas contaminadas vem sendo estudada como forma de redução da persistência e impacto ambiental desse herbicida. Este estudo objetivou avaliar a influência do tempo de cultivo de Urochloa brizantha cv. Piatã sobre a fitorremediação de solo contaminado com picloram. O delineamento experimental utilizado foi em blocos casualizados, com cinco repetições, e os tratamentos foram compostos por cinco períodos de cultivo (150, 210, 240, 270 e 300 dias). Concluiu-se que a braquiária atuou de maneira efetiva na fitorremediação dos solos contaminados, sendo que, quanto maior o período de cultivo, maior foi o seu potencial fitorremediador. Observou-se recuperação no aparato fotossintético das plantas bioindicadoras (Phaseolus vulgaris) estudadas, a partir de 240 dias de cultivo da braquiária.Escola de Agronomia - Universidade Federal de Goiás2014-12-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Experimentalapplication/pdfhttps://revistas.ufg.br/pat/article/view/28377Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 44, n. 4, Oct./Dec. 2014; 460-467Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 44, n. 4, out./dez. 2014; 460-467Pesquisa Agropecuária Tropical; v. 44, n. 4, out./dez. 2014; 460-4671983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/28377/17646Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessFranco, Miguel Henrique RosaFrança, André CabralAlbuquerque, Marco TúlioSchiavon, Nykolas CarvalhoVargas, Guto Nascimento2020-07-13T14:59:19Zoai:ojs.revistas.ufg.br:article/28377Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2020-07-13T14:59:19Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)false
