Resumo: | The grafting in Araucaria angustifolia is an alternative choice related to the production of seedlings using seeds. However, the natural availability of propagules is very limited, since only material obtained from the trunk (orthotropic) could be used. The aim of this study was to evaluate the grafting technique on branches of Araucaria and the graft tropism in order to have the propagule multiplication. The grafting was held in the beginning of July 2014 using the patch grafting technique in 20 plants of 3-year old Araucaria angustifolia. It was used orthotropic buds obtained from trunks and grafted in 43 branches located in the last three upper whorls, within a distance of 10 cm from the rootstock plant trunk. It was evaluated the graft survivals, the healing quality, the tropism (growth angle), the height and diameter of the graft shoots, as well as the diameter of rootstock branches and its relation to the diameter of the graft. Data were analyzed by descriptive statistical tools. The grafting in Araucaria branches is viable. Despite the morphological and functional differences, the interaction among grafts with orthotropic origin and plagiotropic rootstock branches does not interfere in the setting, healing and the initial growth of the grafts, at least up to 180 days after grafting. Therefore, the possibility of grafting in several branches of a same plant configures an alternative option for the multiplication of orthotropic chip. The tropism of shoots depends on the graft origin. Trunciform propagules (obtained from the trunk) are not affected by the interaction when grafted on plagiotropic rootstock branches, showing shoots with orthotropic growth and youth trunk morphology. The upper whorl branches are the most suitable for grafting, aiming the multiplication of orthotropic propagules, because they are less subject to the apical dominance. |

No entanto, a disponibilidade natural de propágulos é muito limitada, uma vez que somente material obtido do tronco (ortotrópico) pode ser utilizado. O objetivo deste trabalho foi avaliar a técnica de enxertia sobre ramos da araucária e o tropismo dos enxertos visando à multiplicação de propágulos. A enxertia foi realizada no início de julho de 2014 por meio da técnica de placagem lenhosa em 20 plantas de Araucaria angustifolia com três anos de idade. Foram utilizadas borbulhas ortotrópicas obtidas de troncos e enxertadas em 43 ramos localizados nos três últimos verticilos superiores, em uma distância de 10 cm do tronco da planta porta-enxerto. Foi avaliada a sobrevivência dos enxertos, a qualidade da cicatrização, o tropismo (ângulo de crescimento), o comprimento e o diâmetro das brotações dos enxertos, bem como o diâmetro dos ramos porta-enxerto e sua relação com o diâmetro da brotação dos enxertos. Os dados foram analisados por meio de ferramentas de estatística descritiva. A enxertia nos ramos da araucária é viável. Apesar das diferenças morfológicas e funcionais, a interação entre enxertos de origem ortotrópica e ramos porta-enxertos plagiotrópicos não interfere no pegamento, na cicatrização e no crescimento inicial dos enxertos, pelo menos até 180 dias após a enxertia. Portanto, a possibilidade de enxertia em vários ramos de uma mesma planta configura uma alternativa para multiplicação de borbulhas ortotrópicas. O tropismo das brotações depende da origem do enxerto. Propágulos trunciformes (obtidos de tronco) não são afetados pela interação quando enxertados em ramos porta-enxertos plagiotrópicos, dando origem a brotações com crescimento ortotrópico e morfologia de tronco juvenil. Os ramos do verticilo superior são os mais indicados para enxertia visando à multiplicação de propágulos ortotrópicos, pois estão menos sujeitos à dominância apical.Universidade Federal de Santa Maria2018-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3210310.5902/1980509832103Ciência Florestal; Vol. 28 No. 2 (2018); 845-853Ciência Florestal; v. 28 n. 2 (2018); 845-8531980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/32103/pdfCopyright (c) 2018 Ciência Florestalinfo:eu-repo/semantics/openAccessConstantino, ValdeciZanette, Flávio2018-06-29T11:07:47Zoai:ojs.pkp.sfu.ca:article/32103Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-06-29T11:07:47Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
