Resumo: This work aimed to study the influence of inoculation of arbuscular mycorrhizal fungi (AMF) Claroideoglomus etunicatum and levels of phosphorus in subsurface substrate of a Latossolo Amarelo biometric parameters in seedlings of Mimosa caesalpiniifolia Benth. The experiment was conducted in a greenhouse, in Bom Jesus in Piauí State, Brazil, October, 2011 to December, 2011. The experimental design was completely randomized in 4x3 factorial scheme, with the factors: phosphorus levels (0, 60, 120 and 240 mg dm-3) and mycorrhizal treatments (no AMF, C. etunicatum and natives AMF). At 65 days after sowing, it was evaluated the biometric parameters plant height, stem diameter, number of leaves, dry weight of roots and shoots, root length, root diameter, root volume, mycorrhizal colonization and mycorrhizal efficiency. Inoculation with C. etunicatum increases seedling growth of M. caesalpiniifolia in substrate subsurface of Latossolo Amarelo under low phosphorus levels. The maximum efficiency occurs in the absence of mycorrhizal phosphate fertilizer. With the increasing levels of phosphorus occurs further growth of Mimosa caesalpiniifolia seedlings and decay in the rate of root colonization by AMF, C. etunicatum and AMF natives.

O experimento foi conduzido em casa de vegetação, no município de Bom Jesus no estado do Piauí, de outubro a dezembro de 2011. O delineamento experimental utilizado foi inteiramente ao acaso em esquema de fatorial 4 x 3 sendo os fatores: níveis de fósforo (0, 60, 120 e 240 mg dm-3) e tratamentos micorrízicos (sem FMA, com C. etunicatum e com FMAs nativos). Aos 65 dias após a semeadura foram avaliados os parâmetros biométricos altura de planta, diâmetro do coleto, número de folhas, massa seca da raiz e parte aérea, comprimento radicular, diâmetro radicular, volume radicular, colonização micorrízica e eficiência micorrízica. Constatou-se que a inoculação com C. etunicatum aumentou o crescimento das mudas de M. caesalpiniifolia em substrato de subsuperfície de Latossolo Amarelo em baixos teores de fósforo. Com a elevação dos níveis de fósforo ocorreu maior crescimento da mudas de M. caesalpiniifolia e diminuição na taxa de colonização radicular por C. etunicatum e FMA nativosos.Embrapa Florestas2013-06-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/46710.4336/2013.pfb.33.74.467Pesquisa Florestal Brasileira; v. 33 n. 74 (2013): abr./jun.; 159-167Pesquisa Florestal Brasileira; Vol. 33 No. 74 (2013): abr./jun.; 159-1671983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/467/pdf_41Oliveira, José Jeremias FernandesAlixandre, Tamnata Ferreirainfo:eu-repo/semantics/openAccess2017-04-28T12:52:27Zoai:pfb.cnpf.embrapa.br/pfb:article/467Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T12:52:27Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
