Resumo: The objective of this work was to study the S translocation and redistribution by acropetal and basipetal transport in corn and soybean plants. Plants of both species were cultivated in nutritive solution containing labeled 35S, in a greenhouse. The 35S applied to only one root was absorbed quickly and transported to the shoot, as well as to the other roots cultivated in non-labeled solution. The 35S applied to only one leaf was transported both to acropetal and basipetal direction. However, corn and soybean showed different behaviors in S absorption and redistribution. In spite of having larger root absorption, corn retained great part of that S in the root, while soybean absorbed considerably less, but presented greater translocation efficiency. The upper leaves, mainly the youngest, showed to be the main physiologic sinks for S in soybean plants.

Plantas das duas espécies foram cultivadas em solução nutritiva contendo 35S em casa de vegetação. O 35S aplicado em uma única raiz foi prontamente absorvido e translocado para a parte aérea, assim como para as demais raízes cultivadas na ausência de enxofre. O radioisótopo aplicado em uma única folha foi transportado tanto na direção acrópeta quanto na basípeta. Entretanto, o milho e a soja mostraram comportamentos diferentes na absorção e na redistribuição do enxofre. O milho, apesar de ter apresentado maior absorção radicular, reteve grande parte desse elemento na raiz, enquanto a soja absorveu consideravelmente menos, porém apresentou maior eficiência de translocação. Nas plantas de soja, as folhas superiores, principalmente as mais novas, mostraram ser os principais drenos fisiológicos do enxofre.–Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilva, Davi JoséVenegas, Víctor Hugo AlvarezRuiz, Hugo AlbertoSant'Anna, Renato2003-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6628Pesquisa Agropecuaria Brasileira; v.38, n.6, jun. 2003; 715-721Pesquisa Agropecuária Brasileira; v.38, n.6, jun. 2003; 715-7211678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6628/3685info:eu-repo/semantics/openAccess2014-08-11T19:12:26Zoai:ojs.seer.sct.embrapa.br:article/6628Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-11T19:12:26Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
