Resumo: | Cnidoscolus quercifolius is an oleaginous plant that can be used for the rehabilitation of degraded areas, feed and food, medicine, sawmill and energy. Clonal propagation of faveleira is a good alternative to seedling production, just like a tool in the plant improvement and to the producers. This study aims to evaluate the efficiency of the air-layering technique on the propagation vegetative of the faveleira, with the view to determine the effect of five concentrations of indolbutyric acid (IBA) and two substrates. We also evaluated the time necessary for the emergence of roots. The experimental design was a randomized complete block design in a 5 x 2 factorial scheme, with 10 repetitions. Each plot consisted of a pruned layers, totaling 100 plots, and treatments combining the five IBA concentrations with the two types of substrates (vermiculite and commercial substrate).There was significant stimulating effect by applying ‘indobultírico’ acid (IBA), to obtain the best results the percentage of air layers roots, root number and root dry mass with a concentration of 6.0 g L-1. The emergence of the roots on the surface of the substrates occurred at 42 days after the completion of the air layering. There was no significant difference between the substrates for any variable. |

A clonagem desta planta é uma boa alternativa de produção de mudas, tanto como uma ferramenta para o melhoramento da espécie como também para os produtores. Objetivou-se avaliar a produção de mudas de faveleira pelo método de alporquia, usando cinco concentrações de AIB e dois substratos. Avaliou-se também o tempo necessário para o surgimento de raízes. O delineamento experimental utilizado foi blocos casualizados, em esquema fatorial 5 x 2, com 10 repetições. Cada parcela experimental constituiu de um alporque, totalizando 100 parcelas, sendo os tratamentos a combinação das cinco concentrações de AIB com os dois tipos de substratos (vermiculita e substrato comercial). Houve efeito estimulante através da aplicação do ácido indolbultírico (AIB), obtendo-se os melhores resultados de porcentagem de alporques enraizados, número de raízes e massa seca das raízes com a concentração de 6,0 g L-1. O surgimento das raízes na superfície dos substratos ocorreu aos 42 dias após a realização dos alporques. Não foi constatada diferença significativa entre os substratos para nenhuma variável.Universidade Federal de Santa Maria2015-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1967710.5902/1980509819677Ciência Florestal; Vol. 25 No. 3 (2015); 743-749Ciência Florestal; v. 25 n. 3 (2015); 743-7491980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/19677/11684Campos, Gustavo Nóbrega FerreiraArriel, Eder FerreiraNoberto, Maria Nilvânia SilvaFarias Junior, José AminthasSilva, Veronica Vicente MonteiroFreire, Antônio Lucineudo Oliveirainfo:eu-repo/semantics/openAccess2017-04-10T18:41:49Zoai:ojs.pkp.sfu.ca:article/19677Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-10T18:41:49Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
