Resumo: | The objective of this work was to evaluate the arbuscular mycorrhizal colonization in peach palm (Bactris gasipaes Kunth) and cupuaçu (Theobroma grandiflorum (Willd ex Spring) K. Schum), in agroforestry systems and monoculture in the Central Amazon region, and to identify anatomic characteristics of mycorrhizal colonization in these species. Soil and root samples were collected in the field, in the dry and rainy season. Mycorrhizal root colonization of cupuaçu and peach palm is affected by the management systems, with higher colonization rates in the monoculture system. Total spore density of the arbuscular mycorrhizal fungi under cupuaçu is not affected by management systems or season, but under peach palm this variation is season dependent. Mycorrhizal colonization of Arum and Paris types occur in peach palm, and only Arum type occurs in cupuaçu. |

Schum) cultivados em sistema agroflorestal e em monocultivo na Amazônia Central, em duas épocas do ano, e também identificar características anatômicas da formação dessa simbiose nessas espécies. Foram realizadas coletas de solo e raízes em duas estações, seca e chuvosa. A colonização micorrízica arbuscular no cupuaçu e na pupunha é alterada pelo sistema de manejo adotado, com taxas maiores de colonização no monocultivo. A densidade total dos esporos de fungos micorrízicos arbusculares sob o cupuaçu não é alterada pelo sistema de manejo ou pela época do ano, ao contrário do que ocorre sob a pupunha. Nessa cultura, a densidade de esporos foi maior sob sistema agroflorestal no período seco. A colonização micorrízica na pupunha apresenta dois padrões anatômicos, Paris e Arum, enquanto no cupuaçu ocorre o padrão Arum.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraJunior, José Pereira da SilvaCardoso, Elke Jurandy Bran Nogueira2006-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7211Pesquisa Agropecuaria Brasileira; v.41, n.5, maio 2006; 819-825Pesquisa Agropecuária Brasileira; v.41, n.5, maio 2006; 819-8251678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7211/4256info:eu-repo/semantics/openAccess2014-09-29T18:45:47Zoai:ojs.seer.sct.embrapa.br:article/7211Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-29T18:45:47Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
