Resumo: | Copper (Cu) is an essential heavy metal for plants at adequate rates, but can be toxic to agricultural species at elevated levels. However, the use of nitrogen-fixing bacteria can be an alternative for growing soybean in Cu-contaminated areas. Tolerance to excess Cu by the roots occurs through immobilization of Cu in the cell wall, exclusion from or restricted uptake, and compartmentalization in the vacuole with soluble complexes. The objective of this study was to determine the influence of the use of fixing bacteria on the development, physiological response, and bioaccumulation of Cu in soybean cultivated in contaminated soil. The experiment was laid out in a completely randomized design, in a 7 × 2 factorial arrangement corresponding to seven rates of Cu (0, 80, 160, 240, 320, 400, and 480 mg kg-1 of soil) and two inoculation possibilities (with Bradyrhizobium japonicum and without inoculation [control]), in eight replicates. The following variables were evaluated: shoot height; stem diameter; number of grains per plant; shoot and root dry weights; leaf area; specific root surface area; Cu contents in the shoot, root, and grains; translocation factor; tolerance index; bioconcentration factor; bioaccumulation coefficient; chlorophyll parameters; and number and dry weight of nodules. Inoculation with B. japonicum increases the physiological traits of plant height, specific root surface area, and grain yield in soybean grown in Cu-contaminated soil. Soybean has low efficiency in translocating Cu to the shoot; however, the copper content in the grain makes it impossible to recommend the cultivation of this crop in soil contaminated with this metal. |

Contudo, a utilização de bactérias fixadoras de nitrogênio pode ser uma alternativa para o cultivo de soja em área contaminado com cobre. A tolerância ao excesso de Cu pelas raízes se dá com a imobilização do Cu na parede celular, exclusão ou restrição da absorção, compartimentalização no vacúolo com complexos solúveis. Objetivou-se neste trabalho determinar a influência do uso de bactérias fixadoras no desenvolvimento, resposta fisiológica e na bioacumulação de cobre na soja cultivada em solo contaminado. O delineamento experimental foi inteiramente casualizado em arranjo fatorial 7 x 2, sendo, sete doses de cobre (0, 80, 160, 240, 320, 400 e 480 mg de cobre kg -1 de solo), duas inoculações (com Bradyrhizobium japonicum e sem inoculação - testemunha), com 8 repetições. Avaliou-se a altura da parte aérea, diâmetro do colo, número de grãos por planta, massa seca da parte aérea e sistema radicular, área foliar, área superficial específica de raízes, teores de cobre na parte aérea, radicular e grãos, índice de translocação e tolerância, fator de bioconcentração, coeficiente de bioacumulação, parâmetros da clorofila, número e massa seca de nódulos. A inoculação com B. japonicum proporciona incrementos nos caracteres fisiológicos, na altura de planta, área superficial específica de raízes e no rendimento de grãos da soja em solo contaminado com cobre. A soja apresenta baixa eficiência em translocar o cobre para parte aérea, porém seu teor no grão inviabiliza sua recomendação de cultivo em solo contaminado com este metal.UEL2022-11-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionRevisão de Literatura; Experimento a campo; Analise estatísticaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4468910.5433/1679-0359.2022v43n5p2339Semina: Ciências Agrárias; Vol. 43 No. 5 (2022); 2339-2358Semina: Ciências Agrárias; v. 43 n. 5 (2022); 2339-23581679-03591676-546Xreponame:Semina.
