Resumo: Vinatic (Plathymenia reticulata Benth.) is one of the native species of Brazil, of economic and environmental interest. Its propagation has been carried out by seeds, however, the difficult access to the matrices, long intervals of fruiting and difficulty of storage, emphasize the importance of techniques that allow the clonal propagation of the species. Studies conducted with vinatic minitumps, coming from seedlings have shown that although the ministumps show good sprouting, the minicutting rooting is very low. The aim of this study was to evaluate the production of vinatic seedlings by minicutting using different management to induce rooting. Two experiments were carried out in a greenhouse and, in the first experiment, the minitumps were obtained from seedlings produced from progenies of eleven matrices, from which the successive collection of minicuttings was promoted, these being submitted to different concentrations of the IBA growth regulator (0, 2.000, 4.000, 6.000 and 8.000 mg.L-1). In the second experiment, light management (shading at buds base and total shading of minitump) and nutrient were used, with nitrogen application (4 g.L-1 urea) in the minitumps. The minicuttings produced were evaluated for rooting capacity and anatomy at the base of the minicuttings. In the first experiment there was a variation of survival and tip pruning tolerance among the progenies of the matrices analyzed, with emphasis on progeny of the DOM matrix, which presented the highest survival percentage in the first collection (88,2%), and a sensitivity of NELI, ZE1 and ZE2 progenies to the management in the clonal minigarden. Vinatic responded positively to the successive collection of sprouts, with an increase in the number of sprouts produced from the fourth month of collection (210 days). There was no significant effect on rooting of vinatic plants when submitted to increasing concentrations of IBA, nor on the type of light and nitrogen management used to stimulate the minicuttings rooting. No anatomical barriers were observed to the rooting of the minicuttings in the different managements evaluated.

Sua propagação tem sido realizada por sementes, entretanto, o difícil acesso às matrizes, os intervalos longos de frutificação e dificuldade de armazenamento destacam a importância de técnicas que permitam a propagação clonal da espécie. Estudos conduzidos com minicepas de vinhático, advindas de mudas produzidas por sementes têm demonstrado que, embora as minicepas apresentem boa brotação, o enraizamento das miniestacas é muito baixo. Com isso, objetivou-se neste trabalho, avaliar a produção de mudas de vinhático por miniestaquia, utilizando diferentes técnicas de manejo para induzir o enraizamento. Foram realizados dois experimentos em casa de vegetação, sendo que, no primeiro, as minicepas foram obtidas a partir de mudas produzidas via semente de progênies de onze matrizes, das quais se promoveu a coleta sucessiva de miniestacas, sendo estas submetidas a diferentes concentrações do regulador de crescimento AIB (0, 2.000, 4.000, 6.000 e 8.000 mg.L-1). No segundo experimento foi utilizado o manejo de luz (sombreamento na base da brotação e sombreamento total da minicepa) e de nutriente, com aplicação de nitrogênio (4 g.L-1 de ureia) nas minicepas. As miniestacas produzidas foram avaliadas quanto à capacidade de enraizamento e anatomia na base da miniestaca. No primeiro experimento verificou-se uma variação de sobrevivência e tolerância à poda apical entre as progênies das matrizes analisadas, com destaque para progênie da matriz DOM, que apresentou o maior percentual na primeira coleta (88,2%), e uma sensibilidade das progênies NELI, ZE1 e ZE2 aos efeitos do manejo e às condições ambientais no minijardim clonal. O vinhático respondeu de forma positiva à coleta sucessiva de brotações, com aumento do número de brotações produzidas a partir do quarto mês de coleta (210 dias). Não houve efeito significativo no enraizamento de mudas de vinhático quando submetido a concentrações crescentes de AIB, nem quanto ao tipo de manejo de luz e nitrogênio utilizados para estimular o enraizamento de miniestacas. Não foram observadas barreiras anatômicas ao enraizamento dos clones nos diferentes tipos de manejos avaliados.Universidade Federal de Santa Maria2018-12-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3531710.5902/1980509835317Ciência Florestal; Vol. 28 No. 4 (2018); 1688-1703Ciência Florestal; v. 28 n. 4 (2018); 1688-17031980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/35317/pdfCopyright (c) 2018 Ciência Florestalinfo:eu-repo/semantics/openAccessPessanha, Sara Edy Gomes LimaBarroso, Deborah GuerraBarros, Thaís ChagasOliveira, Taiane Pires de Freitas deCarvalho, Giovanna Campos Mamede Weiss deCunha, Maura da2018-12-16T20:33:04Zoai:ojs.pkp.sfu.ca:article/35317Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-12-16T20:33:04Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
