Resumo: The effects of soil-applied synthetic formononetin (7-hydroxy 4'methoxi-isoflavone) on arbuscular mycorrhizal colonization, plant growth and nutrient content of soybean (Glycine max L. Merril) inoculated or not with different mycorrhizal fungi were studied. The experiment was conducted in plastic pots containing 1.6 kg of a Dusk-Yellow Latossol (Oxisol) with 2 mg/kg of P. Plants were submitted to inoculation with Acaulospora morrowiae Spain & Schenck, Gigaspora margarita Becker & Hall, Glomus clarum Nicol. & Schenck, Glomus etunicatum Becker & Gerdemann and Scutellospora heterogama Nicol. & Gerdemann Walker & Sanders) in the presence and absence of formononetin (5µg/mL) applied as solution form at the sowing time. Formononetin enhanced mycorrhizal formation by all fungal species. However, such effects were influenced by the growth period and parameter of colonization. Plant growth, nodulation and leaf nutrient content were stimulated by inoculation, but not by application of formononetin. G. etunicatum was the most effective species for soybean, independent of formononetin application.

Merril) submetida à inoculação de diferentes espécies de fungos micorrízicos arbusculares (FMAs). O estudo foi conduzido em casa de vegetação, em vasos com 1,6 kg de Latossolo Vermelho-Amarelo, fumigado, contendo 2 mg/kg de P (Mehlich I). As plantas receberam inoculação dos FMAs (Acaulospora morrowiae Spain & Schenck,Gigaspora margarita Becker & Hall, Glomus clarum Nicol. & Schenck, Glomus etunicatum Becker & Gerdemann e Scutellospora heterogama Nicol. & Gerdemann Walker & Sanders) e aplicação ou não ao solo, por ocasião da semeadura, de solução de formononetina contendo 5 µg/mL. Todos os fungos foram estimulados pela aplicação de formononetina, porém esse efeito foi diferenciado quanto a época e parâmetro considerado. O crescimento, a nodulação e os teores de nutrientes da soja foram favorecidos pela inoculação dos FMAs, mas não pela aplicação de formononetina. G. etunicatum foi a espécie mais eficiente para a soja, independentemente da presença de formononetina.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPereira da Silva Júnior, JoséOswaldo Siqueira, José1998-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4922Pesquisa Agropecuaria Brasileira; v.33, n.6, jun. 1998; 953-959Pesquisa Agropecuária Brasileira; v.33, n.6, jun. 1998; 953-9591678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4922/7049info:eu-repo/semantics/openAccess2014-12-10T18:44:49Zoai:ojs.seer.sct.embrapa.br:article/4922Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-12-10T18:44:49Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
