Resumo: | The olive tree, due to the high demand for the products olive and oil, is a relevant crop for the global food market. To improve its cultivation, increasing efforts have been invested in studies on biological factors of the soil-plant relationships, mainly with regard to the exploitation of microorganisms such as arbuscular mycorrhizal fungi (AMF). In Brazil however, further research is still needed, both under controlled and field conditions. In this sense, this study investigated the formation of extraradical mycelium and spore numbers and diversity of mycorrhiza, on 17 olive tree (Olea europaea L.) varieties. These varieties, considered promising for cultivation in the state of Minas Gerais, are maintained in the olive germplasm bank of the Agricultural Research Institute of Minas Gerais (EPAMIG), at the Experimental Farm Maria da Fé. The response of the olive varieties differed in terms of the level of extraradical mycelium and mycorrhiza formation, since root colonization in the field varied from 0.4% to 3.6%. Under the edaphoclimatic conditions of the study region, no influence of the olive tree varieties on the total number of spores and diversity of AMF was detected, among which the fungal species Glomus ambisporum and Acaulospora scrobiculata were identified most frequently on the roots of the analyzed olive trees. |

Para o aprimoramento de seu cultivo, pesquisas relacionadas com fatores de ordem biológica da relação solo-planta estão ganhando enfoque, principalmente quanto ao uso de microrganismos como fungos micorrízicos arbusculares (FMAs). Contudo, há uma grande escassez de informação nessa área no Brasil, tanto em condições controladas quanto realizadas in situ. Nesse sentido, o presente trabalho visou avaliar a formação de propágulos (usando as características micélio extrarradicular, número e diversidade de esporos) de micorrizaem17 variedades de oliveira (Olea europaea L.). Essas variedades, com potencial de cultivo no estado de Minas Gerais, são mantidas no banco de germoplasma da Fazenda Experimental de Maria da Fé – EPAMIG (Empresa Brasileira de Pesquisa Agropecuária de Minas Gerais). Houve resposta distinta entre as variedades de oliveira para a formação de micélio extrarradicular e micorriza, sendo a colonização radicular in situ variada entre 0,4% e 3,6%. Nas condições edafoclimáticas da região de pesquisa não foi detectada nenhuma influência das variedades de oliveira sobre o número total de esporos e a diversidade de FMAs, sendo que as espécies Glomus ambisporum e Acaulospora scrobiculata foram identificadas com maior frequência nas raízes das oliveiras analisadas.Universidade Federal de Santa Maria2020-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3878110.5902/1980509838781Ciência Florestal; Vol. 30 No. 4 (2020); 1255-1265Ciência Florestal; v. 30 n. 4 (2020); 1255-12651980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/38781/pdfCopyright (c) 2020 Ciência Florestalinfo:eu-repo/semantics/openAccessMelloni, RogerioSalomão, Fabrício RezendeCardoso, Elke Jurandy Bran NogueiraMescolotti, Denise de Lourdes ColomboSilva, Luiz Fernando de Oliveira da2021-05-20T04:00:49Zoai:ojs.pkp.sfu.ca:article/38781Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2021-05-20T04:00:49Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
