Resumo: The objective of this study was to evaluate the mycorrhizal dependency of mangaba tree (Hancornia speciosa) plantlets, under increasing levels of phosphorus fertilization. The experimental design was completely randomized in a 4´5 factorial arrangement with three mycorrhizal fungi inocula – Gigaspora margarita, Glomus etunicatum, or a pool of native mycorrhizal fungi (Acaulospora longula, Glomus clarum, Gigaspora albida, Paraglomus sp.) –, and a nonmycorrhizal control, in combination with five levels of phosphorus applied to the substrate: 0, 25, 50, 75, and 100 mg kg-1. After 180 days of growth, plantlets with inoculation of native mycorrhizal pool produced more shoot and root dry biomass and had higher shoot phosphorus content and accumulation. The noninoculated control showed the lowest values, independently of the phosphorus level. The highest relative mycorrhizal dependency occurred with the inoculation of native mycorrhizal fungi. Plants with mycorrhizal fungi did not respond to phosphorus addition above 50 mg kg-1. Mangaba tree is highly dependent on mycorrhiza, but the degree of dependency varies according to phosphorus levels and fungal inocula. In general, mangaba tree is more responsive to mycorrhizal fungi inoculation than to phosphorus addition.

O delineamento experimental foi inteiramente casualizado, em arranjo fatorial 4´5 com três inóculos de fungos micorrízicos – Gigaspora margarita, Glomus etunicatum, ou uma mistura de espécies de fungos micorrízicos nativos (Acaulospora longula, Glomus clarum, Gigaspora albida e Paraglomus sp.) –, e um controle não micorrízico, combinados a cinco doses de fósforo no substrato: 0, 25, 50, 75 e 100 mg kg-1. Após 180 dias, as mudas com inoculação dos fungos micorrízicos nativos produziram mais biomassa seca de parte aérea e raízes e apresentaram maior concentração e acúmulo de fósforo na parte aérea. O controle sem inóculo apresentou os menores valores, independentemente da dose de fósforo. A maior dependência micorrízica relativa ocorreu com a inoculação de fungos micorrízicos nativos. Plantas com inoculação micorrízica não responderam à adição de fósforo, em doses acima de 50 mg kg-1. A mangabeira é altamente dependente de micorrizas, mas o grau de dependência varia de acordo com os níveis de fósforo e com os inóculos fúngicos. Em geral, a mangabeira é mais responsiva à inoculação com fungos micorrízicos do que à adição de fósforo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFilho, Júlio Alves CardosoLemos, Eurico Eduardo Pinto deSantos, Tania Marta Carvalho dosCaetano, Luis CarlosNogueira, Marco Antonio2008-10-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/401Pesquisa Agropecuaria Brasileira; v.43, n.7, jul. 2008; 887-892Pesquisa Agropecuária Brasileira; v.43, n.7, jul. 2008; 887-8921678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/401/5483https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/401/303https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/401/304info:eu-repo/semantics/openAccess2014-06-27T17:18:03Zoai:ojs.seer.sct.embrapa.br:article/401Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-06-27T17:18:03Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
