Resumo: | Currently, southern Minas Gerais (MG) state is an important producer of different olive tree (Olea europaea L.) cultivars because, in this region, the plants can differentiate the buds to produce flowers and fruit. To stimulate the rooting of cuttings, the synthetic hormone indole-3-butyric acid (IBA) at a concentration of 3 g L−1 is used commercially. However, few studies have investigated arbuscular mycorrhizal fungi (AMF), isolated or combined with rhizobacteria, as a biotechnological tool to produce hormones that function in the rooting of olive tree cuttings. The aim of this study was to evaluate the capacity of different AMF species (Rhizophagus clarus, Gigaspora rosea, or Acaulospora scrobiculata), combined or not with IBA or rhizobacteria, to promote the rooting of three olive tree cuttings (Arbequina, Grappolo 541, and Maria da Fé) with potential for cultivation in this region. For this, three experiments were conducted at the Experimental Farm of EPAMIG in Maria da Fé (MG), and the rooting potential of the olive tree cuttings inoculated with I) AMF, II) AMF combined with increasing doses of IBA, and III) AMF combined with three isolates of rhizobacteria was evaluated. The inoculation of olive tree cuttings of cultivars Arbequina, Grappolo 541, and Maria da Fé with Rhizophagus clarus, Gigaspora rosea, or Acaulospora scrobiculata combined or not with IBA or rhizobacteria did not significantly promote rooting. Alternative forms of rooting olive tree cuttings are still a challenge, and further studies for standardizing methodologies and experimental conditions are required. |

Para estimular o enraizamento das estacas, o hormônio sintético ácido indol-3-butírico (AIB), na concentração de 3 g L-1, tem sido utilizado comercialmente. No entanto, poucos estudos investigaram fungos micorrízicos arbusculares (FMA), isolados ou combinados com rizobactérias, como uma ferramenta biotecnológica para a produção de hormônios que atuam no enraizamento de estacas de oliveiras. O objetivo deste trabalho foi avaliar a capacidade de diferentes espécies de FMA (Rhizophagus clarus, Gigaspora rosea ou Acaulospora scrobiculata), combinadas ou não com AIB ou rizobactérias, de promover o enraizamento de estacas de 3 cultivares de oliveira (Arbequina, Grappolo 541 e Maria da Fé) com potencial para cultivo nessa região. Para isso, três experimentos foram conduzidos na Fazenda Experimental da EPAMIG em Maria da Fé (MG), avaliando-se o potencial de enraizamento de estacas de oliveiras inoculadas com I) FMA, II) FMA combinados com doses crescentes de AIB e III) FMA combinados com três isolados de rizobactérias. A inoculação de estacas de oliveira das cultivares Arbequina, Grappolo 541 e Maria da Fé com Rhizophagus clarus, Gigaspora rosea ou Acaulospora scrobiculata, combinadas ou não com IBA ou rhizobacteria, não promoveu significativamente o enraizamento de estacas de oliveira. Formas alternativas de enraizamento de estacas de oliveira ainda são um desafio, sendo necessários mais estudos para padronizar metodologias e condições experimentais.EDUFU2022-11-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/5357010.14393/BJ-v38n0a2022-53570Bioscience Journal ; Vol. 38 (2022): Continuous Publication; e38091Bioscience Journal ; v. 38 (2022): Continuous Publication; e380911981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/53570/35103Brazil; Contemporary Copyright (c) 2022 Gustavo Magno dos Reis Ferreira, Luiz Fernando de Oliveira Silva, Moacir Pasqual, Rogério Melloni, José Magno Queiroz Luz, Joyce Dória R.
