Resumo: The present work was developed with the objective to evaluate the accumulation of Pb in plant tissue of castor bean (Ricinus communis L.) in contaminated soil and investigate the potential for soil remediation. The experiment was carried out in a greenhouse at the Faculty of Agricultural Sciences/UNOESTE – Presidente Prudente/SP. Plants were grown in pots with a capacity of 9 dm3 of soil. The treatments were in addition to the vessels of 18.8 mg kg-1, 37.5 mg kg-1, 75 mg kg-1, 150 mg kg-1, 300 mg kg-1, 600 mg kg-1 and 1200 mg kg-1 in the form of Pb (Pb(NO3)2). Treatments were arranged according to completely randomized design with three replications. Samples of soil and plant tissue were collected ninety days after sowing for the quantification of mass of dry matter of shoots and roots, and for determining the accumulation of lead in tissues of both species. The parameters were subjected to analysis of variance evaluating the effect of treatments by the Tukey test at 5% level of probability. The results presented by significant F-test were submitted to polynomial regression. The castor beans had a higher accumulation of Pb in roots, there was a decrease in plant growth due to a reduction of mass of dry matter of shoots and roots with the gradual increase of the concentration of Pb in soil and the addition of 1200 mg kg-1 Pb in soil was more effective in reducing the growth of castor bean.

O experimento foi desenvolvido em ambiente protegido da Faculdade de Ciências Agrárias/UNOESTE – Presidente Prudente/SP. As plantas foram cultivadas em vasos com capacidade para 9 dm3 de solo. Os tratamentos consistiram em adição nos recipientes de 18,8 mg kg-1; 37,5 mg kg-1; 75 mg kg-1; 150 mg kg-1; 300 mg kg-1; 600 mg kg-1 e 1.200 mg kg-1 de Pb na forma de (Pb(NO3)2). Os tratamentos foram distribuídos de acordo com delineamento estatístico inteiramente casualizado, com três repetições. Amostras do solo e do tecido vegetal foram coletadas noventa dias após a semeadura para a quantificação das massas das matérias secas da parte aérea e das raízes e para a determinação do acúmulo de chumbo nos tecidos vegetais de ambas as espécies. Os parâmetros avaliados foram submetidos à análise de variância avaliando-se o efeito dos tratamentos pelo teste de Tukey a nível de 5% de probabilidade. Os resultados significativos apresentados pelo Teste F foram submetidos à regressão polinomial. As mamoneiras apresentaram maior acúmulo de Pb nas raízes, houve uma diminuição do crescimento das plantas em função da diminuição das massas das matérias secas da parte aérea e das raízes com o aumento gradual da concentração de Pb no solo e, a adição de 1200 mg kg-1 de Pb no solo foi mais efetiva para a diminuição do crescimento das mamoneiras.UEL2012-08-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresPesquisa Experimentalapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/693310.5433/1679-0359.2012v33n4p1427Semina: Ciências Agrárias; Vol. 33 No. 4 (2012); 1427-1434Semina: Ciências Agrárias; v. 33 n. 4 (2012); 1427-14341679-03591676-546Xreponame:Semina.
