Resumo: The objective of the present study was to evaluate the influence of six arbuscular mycorrhizal fungi (AMF) species (Glomus clarum, Scutellospora heterogama, Glomus etunicatum, Acaulospora scrobiculata, Gigaspora margarita and Glomus manihotis) on vegetative growth, mineral nutrition and carbohydrate contents of avocado (Persea sp.) rootstocks. These were cultivated in 5 L bags of black polyethylene containing substrate mixture of soil + silica sand + decomposed bark residue of acacia (Acacia mearnii) (2:2:1, v:v:v). The rootstocks were kept in a sombrite (70% shading) greenhouse. Two months after AMF inoculation, the results indicated that AMF influence on avocado rootstocks growth is variable depending on AMF species. S. heterogama, A. scrobiculata and G. etunicatum were more effective, resulted in good nutrition and carbohydrate contents of avocado rootstocks, and consequently resulted better vegetative growth of plants. G. clarum only increased stem height of the rootstocks, while G. manihotis did not affect vegetative growth of avocado rootstocks. G. margarita was harmful to avocado rootstocks growth.

Os porta-enxertos foram cultivados em casa de vegetação com cobertura de sombrite (70%) e acondicionados em sacos de polietileno preto (5 L), contendo substrato constituído de solo + areia + resíduo decomposto de casca de acácia-negra (Acacia mearnii) (2:2:1, v:v:v). Dois meses após a infecção das plântulas com FMA (30 g/plântula), observou-se que a dependência do abacateiro aos FMA variou com a espécie de fungo em estudo. Scutellospora heterogama, Acaulospora scrobiculata e Glomus etunicatum proporcionaram melhor nutrição, maior conteúdo em substâncias de reserva e maior desenvolvimento vegetativo das plantas. Glomus clarum somente incrementou a altura das plantas. A infecção com Glomus manihotis não alterou o desenvolvimento vegetativo dos porta-enxertos, e Gigaspora margarita foi prejudicial.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilveira, Samar Velho daSouza, Paulo Vítor Dutra deKoller, Otto Carlos2002-03-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6342Pesquisa Agropecuaria Brasileira; v.37, n.3, mar. 2002; 303-309Pesquisa Agropecuária Brasileira; v.37, n.3, mar. 2002; 303-3091678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6342/3399info:eu-repo/semantics/openAccess2010-09-02T18:26:16Zoai:ojs.seer.sct.embrapa.br:article/6342Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-09-02T18:26:16Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
