Resumo: | The objective of this study was to verify the influence of allelopathic compounds released by Brachiaria brizantha cv. Marandu on the tolerance of plant growth-promoting bacteria (PGPB). Extracts of shoots and roots of B. brizantha were obtained at concentrations of 12.5; 25.0; 50.0 and 75.0% and evaluated the effect on the growth of 10 PGPB strains using agar drilling and serial dilution methodologies. The experiment was installed in a completely randomized design (CRD) in a factorial scheme, 10 x 5 x 2 with 4 replications, 10 bacterial strains, 5 constituting the four different concentrations and a control treatment (without extract) and 2 extracts of allelopathic compounds, shoot and root, of B. brizantha. Inhibition was verified by the root extract at a concentration of 75% for the UNIFENAS 100-01 strains; 100-13; 100-39; 100-02 and 100-94 by the agar perforation method. The other strains grew normally in the culture medium at all concentrations. According to the data obtained, it was possible to observe that allelopathic extracts of B. brizantha may interfere with the growth of PGPB strains, which may compromise their efficiency when used as inoculants. |

Marandu sobre la tolerancia de las bacterias promotoras del crecimiento vegetal (BPCV). Se obtuvieron extractos de brotes y raíces de B. brizantha a concentraciones de 12,5; 25,0; 50,0 y 75,0% y evaluó el efecto sobre el crecimiento de 10 cepas de BPCV utilizando metodologías de perforación en agar y dilución en serie. El experimento se instaló en un diseño completamente aleatorizado (DCA) en esquema factorial, 10 x 5 x 2 con 4 repeticiones, 10 cepas bacterianas, 5 constituyendo las cuatro diferentes concentraciones y un tratamiento control (sin extracto) y 2 extractos de compuestos alelopáticos, brote y raíz, de B. brizantha. La inhibición fue verificada por el extracto de raíz a una concentración de 75% para las cepas UNIFENAS 100-01; 100-13; 100-39; 100-02 y 100-94 por el método de perforación de agar. Las otras cepas crecieron normalmente en el medio de cultivo en todas las concentraciones. De acuerdo con los datos obtenidos, fue posible observar que los extractos alelopáticos de B. brizantha pueden interferir en el crecimiento de las cepas de BPCV, lo que puede comprometer su eficiencia cuando se utilizan como inoculantes.Objetivou-se com este estudo verificar a influência de compostos alelopáticos liberados por Brachiaria brizantha cv. Marandu na tolerância de bactérias promotoras do crescimento vegetal (BPCV). Foram obtidos extratos da parte aérea e raiz de B. brizantha nas concentrações de 12,5; 25,0; 50,0 e 75,0% e avaliado o efeito no crescimento de 10 estirpes de BPCV utilizando as metodologias de perfuração em ágar e diluição seriada. O experimento foi instalado em delineamento inteiramente casualizado (DIC) em esquema fatorial, 10 x 5 x 2 com 4 repetições, sendo 10 estirpes bacterianas, 5 constituindo as quatro diferentes concentrações e um tratamento controle (sem extrato) e 2 extratos de compostos alelopáticos, parte aérea e radicular, de B. brizantha. Foi verificado inibição pelo extrato radicular na concentração de 75% para as estirpes UNIFENAS 100-01; 100-13; 100-39; 100-02 e 100-94 pelo método da perfuração do ágar. As demais estirpes cresceram normalmente no meio de cultura em todas as concentrações. De acordo com os dados obtidos foi possível observar que os extratos alelopático de B. brizantha podem interferir no crescimento de estirpes de BPCV, podendo comprometer a eficiência destas quando utilizadas como inoculantes.Research, Society and Development2022-02-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2628710.33448/rsd-v11i3.26287Research, Society and Development; Vol. 11 No. 3; e3311326287Research, Society and Development; Vol. 11 Núm. 3; e3311326287Research, Society and Development; v. 11 n. 3; e33113262872525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/26287/22961Copyright (c) 2022 Carla Neves Toledo; Elisa Rocha; Bruna Aparecida Araújo; Nhayandra Christina Dias Silva; Adauton Vilela Rezende; Ligiane Aparecida Florentinohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessToledo, Carla NevesRocha, ElisaAraújo, Bruna AparecidaSilva, Nhayandra Christina DiasRezende, Adauton VilelaFlorentino, Ligiane Aparecida 2022-03-09T13:44:38Zoai:ojs.pkp.sfu.ca:article/26287Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:44:22.016378Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
