Resumo: | Due to deforestation in Gallery Forests, the current environmental law requires their restoration. Using only seminal propagation for native species of this environment has limited the production of seedlings as the seeds of some species often have limiting factors. Richeria grandis Vahl., besides being a characteristic species of this environment, has high value in phytosociological importance; however, it has recalcitrant seeds. In view of this, the objective was to evaluate the rooting of R. grandis Vahl. mini-cuttings under the influence of indolebutyric acid (IBA) concentrations. Apical mini-cuttings were prepared with length of 8 ± 2 cm and two pairs of leaves with their leaf area reduced by 50%. For rooting, a mixture of 70% vermiculite and 30% carbonized rice husk with fertilizer was used as substrate. As treatments, four IBA concentrations were tested: 0; 2,000; 4,000; and 6,000 mg L-1, liquid in solution, for 10 seconds. The rooting of mini-cuttings was conducted in a greenhouse, for a period of 90 days. According to the results, this technique is feasible, since there was 100% survival and a high percentage of rooting, with the control treatment having the lowest value (85%). Calluses were found in non-rooted mini-cuttings and, using IBA, there was a tendency to increase the mean number of roots, sprouting percentage and mean sprouts per treatment. |

Apenas o uso da propagação seminal para espécies nativas deste ambiente tem limitado a produção de mudas, visto que sementes de algumas espécies muitas vezes possuem algum fator limitante. Richeria grandis Vahl. além de ser uma espécie característica deste ambiente, apresenta alto valor de importância fitossociológica, no entanto, suas sementes são recalcitrantes. Diante disto, objetivou-se avaliar o enraizamento de miniestacas de R. grandis Vahl. sob influência de concentrações de ácido indolbutírico (AIB). As miniestacas apicais foram preparadas com comprimento de 8 ± 2 cm e dois pares de folhas reduzidas em 50% a área foliar. Para o enraizamento, foi utilizado como substrato, a mistura de 70% de vermiculita e 30% de casca de arroz carbonizada com adição de fertilizante. Como tratamentos, foram testadas quatro concentrações de AIB: 0; 2.000, 4.000 e 6.000 mg L-1, via líquida, durante 10 segundos. O processo de enraizamento das miniestacas foi conduzido em casa de vegetação, por um período de 90 dias. De acordo com os resultados, esta técnica é viável, uma vez que houve 100% de sobrevivência e alta porcentagem de enraizamento, sendo o tratamento controle com o menor valor (85%). Observou-se a presença de calos em miniestacas não enraizadas e, com o uso de AIB, houve tendência de aumento do número médio de raízes, porcentagem de brotação e média de brotos por tratamento.engUniversidade Federal de Minas GeraisUFMGBrasilICA - INSTITUTO DE CIÊNCIAS AGRÁRIASRevista Brasileira de Ciências AgráriasArvores - MudasFlora dos cerradosBrotos (Plantas)Raizes (Botanica)Gallery ForestsIndolebutyric acidRecalcitrantRootingSeedling productionVegetative propagation of Richeria grandis Vahl. by mini-cuttingPropagação vegetativa de Richeria grandis Vahl. por miniestaquiainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://www.agraria.pro.br/ojs32/index.php/RBCA/article/view/v15i4a7930Cristiane Coelho MouraThaís Ribeiro CostaLuciana Coelho MouraLeticia Renata de CarvalhoMiranda TitonIsrael Marinho PereiraEvandro Luiz Mendonça Machadoinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/52737/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALVegetative propagation of Richeria grandis Vahl by mini-cutting_Letícia Renata de Carvalho.pdfVegetative propagation of Richeria grandis Vahl by mini-cutting_Letícia Renata de Carvalho.pdfapplication/pdf1293608https://repositorio.ufmg.br/bitstream/1843/52737/2/Vegetative%20propagation%20of%20Richeria%20grandis%20Vahl%20by%20mini-cutting_Let%c3%adcia%20Renata%20de%20Carvalho.pdf9d989b7577538b61868e8bb56960de1dMD521843/527372023-05-02 20:10:06.598oai:repositorio.ufmg.br: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Repositório de PublicaçõesPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-05-02T23:10:06Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false |
