Resumo: The objective of this work was to evaluate the effects of soil P availability, mycorrhiza and a mycorrhiza stimulatory product (Mycoform) upon growth and initial competition of six sown woody species, in the greenhouse. The species Senna macranthera, Guazuma ulmifolia, Senna multijuga, Solanum granuloso-leprosum, Schinus terebenthifolius and Trema micrantha were sown together in a soil with very low, low and high levels of P in soil solution combined with inoculation treatments of the arbuscular mycorrhizal fungus Glomus etunicatum, G. etunicatum + Mycoform and a non-inoculated control. Growth response to mycorrhizal inoculation occurred with very low and low phosphorus. The seedlings presented moderate mycorrhizal dependency, because there was no response with high phosphorus. Solanum granuloso-leprosum died with very low P, but was the dominant specie with low and high P, and very responsive to phosphorus. Senna macranthera was dominant only with very low P, indicating that it is quite adapted to low fertility soils. Glomus etunicatum influenced the species dominance, promoting the least competitive species and favoring uniformity in plant growth. Growth, nutrition and competition were little influenced by Mycoform. The growth of pioneer species is favored by increasing P availability and by mycorrhiza which also favores the growth equilibrium between them in mixed and direct seeding on low fertility soil.

O trabalho foi realizado em casa de vegetação com as espécies Senna macranthera (fedegoso), Guazuma ulmifolia (mutamba), Senna multijuga (cássia-verrugosa), Solanum granuloso-leprosum (gravitinga), Schinus terebenthifolius (aroeira) e Trema micrantha (trema), em solo com níveis de P na solução considerados muito baixo, baixo e alto, com inoculação ou não do fungo micorrízico arbuscular G. etunicatum, além do tratamento G. etunicatum + Mycoform. O crescimento das mudas respondeu à inoculação em P muito baixo e baixo. As mudas apresentaram moderada dependência das micorrizas, não respondendo ao G. etunicatum em P alto. Gravitinga morreu em P muito baixo, mas foi dominante com P baixo e alto. Fedegoso foi dominante com P muito baixo, mostrando-se adaptado à baixa fertilidade. G. etunicatum influenciou a dominância das espécies, auxiliando as menos competitivas e gerando maior equilíbrio. Mycoform influenciou pouco o crescimento, nutrição e competição. O crescimento de espécies pioneiras semeadas diretamente é favorecido pela elevação do P e pelas micorrizas, as quais também favorecem o equilíbrio entre espécies.–Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAylas, Waldo Wilfredo FloresJúnior, Orivaldo José SagginSiqueira, José OswaldoDavide, Antônio Cláudio2003-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6569Pesquisa Agropecuaria Brasileira; v.38, n.2, fev. 2003; 257-266Pesquisa Agropecuária Brasileira; v.38, n.2, fev. 2003; 257-2661678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6569/3626info:eu-repo/semantics/openAccess2010-08-16T17:37:08Zoai:ojs.seer.sct.embrapa.br:article/6569Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-16T17:37:08Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
