Resumo: Sapium glandulatum (Vell.) Pax (Euphorbiaceae) is a native and rustic tree found in different Brazilian plant formations, and is much indicated for recovery of degraded ecosystems. However, the sexual propagation is very difficult because almost every flower is male, the seed production is poor and the percentage of seed germination is low. The mini-cuttings technique is an alternative to other methods of propagation that allow the rooting with young material. Thus, the present work aimed to test the sprouts production and rooting by mini-cuttings of Sapium glandulatum (Vell.) Pax originating from young seedlings, collected in four seasons (autumn, winter, spring 2006 and summer 2007), in Colombo - PR, Brazil. The mini-cuttings were trimmed to 3 cm in length, with two half leafs in apical region. Indolebutyric acid (IBA) and naphtalene acetic acid (NAA) were applied in the base of the mini-cuttings at 0, 2000, 4000, 6000 and 8000 mgL-1 for 10 seconds. The percentage of rooted mini-cuttings, amount and root length, percentage of mini-cuttings with callus, survival and mortality rate were evaluated in a experimental random delineation, with factorial range of the treatments: 2x5x4 (kinds of plant growth regulator x concentration of plant growth regulator x seasons). The mini-cuttings p production/mini-tumps range between 1.4 until 2.2 in 205 cm³ recipient. The best season for rooting was winter, with 80.56% of rooting when the vegetal regulator was not used. It is concluded from this study that the vegetative propagation of Sapium glandulatum (Vell.) Pax by mini-cuttings collected from young seedlings can be used for rooting.

Pax. (Euphorbiaceae) é uma árvore nativa de vários biomas brasileiros, com grande interesse para a recuperação de ecossistemas degradados devido a sua rusticidade. Entretanto, sua propagação sexuada apresenta dificuldades devido, principalmente, a pouca produção de sementes, baixa taxa de germinação e grande quantidade de flores masculinas. A miniestaquia constitui uma alternativa para a propagação da espécie, a qual pode fornecer material juvenil favorável ao enraizamento. Esta pesquisa teve como objetivo avaliar o enraizamento e a produção de miniestacas por minicepa provenientes de mudas originadas por via seminal, coletadas nas quatro estações do ano (inverno, primavera, verão de 2006 e outono de 2007), no município de Colombo - PR, Brasil. As miniestacas foram confeccionadas com 3-5 cm de comprimento e um par de folhas na porção apical, com sua área reduzida pela metade. Estas foram submetidas a tratamentos com o uso dos reguladores vegetais ácido indol butírico (IBA) e ácido naftaleno acético (NAA). Os reguladores foram utilizados na forma de solução por 10 segundos nas bases das miniestacas em concentrações de 0, 2000, 4000, 6000, 8000 mgL-1. Foram avaliados o percentual de miniestacas enraizadas, o número e comprimento das raízes formadas, o percentual de miniestacas com calos, a sobrevivência e mortalidade, em um delineamento experimental inteiramente casualizado com arranjo fatorial 2x5x4 (tipos de reguladores vegetais x concentrações dos reguladores vegetais x estações do ano). A produção de miniestacas por minicepa a cada coleta variou de 1,4 a 2,2 em recipientes contendo 205 cm3. A estação do inverno mostrou-se promissora para o enraizamento adventício de miniestacas, apresentando 80,56% sem a aplicação dos reguladores vegetais sendo, portanto, desnecessária a aplicação destes para a indução radicial. Desta forma, a técnica de miniestaquia de propágulos oriundos de mudas produzidas por semente é viável e pode ser recomendada para o enraizamento da espécie.Universidade Federal de Santa Maria2010-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/175810.5902/198050981758Ciência Florestal; Vol. 20 No. 1 (2010); 19-31Ciência Florestal; v. 20 n. 1 (2010); 19-311980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1758/1025Ferreira, Bárbara Guerreira AlpandeZuffellato-Ribas, Katia ChristinaWendling, IvarKoehler, Henrique SoaresNogueira, Antonio Carlosinfo:eu-repo/semantics/openAccess2017-05-08T11:10:43Zoai:ojs.pkp.sfu.ca:article/1758Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-08T11:10:43Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
