Resumo: The importance of Eucalyptus and Corymbia has been evident in forestry programs, mainly due to their adaptation to various environmental conditions and the multiple products that can be obtained. As the selection and cloning of superior individuals are usually performed in adulthood, the development and adaptation of the vegetative propagation techniques that enable the rescue and in vitro establishment of species are necessary. Thus, the present study aimed to induce epicormic shoots from pruned branches of adult trees and to promote the in vitro establishment of nine species: six of Eucalyptus and three of Corymbia. The material used to obtain the explants came from the selection of two 44-year-old mother plants of each species, from species, and provenance tests. The number of buds and shoots of each branch was evaluated at 15, 25, 35, and 45 days after the beginning of the experiment in a greenhouse. According to the results, the induction of epicormic shoots from pruned branches was considered a viable and efficient technique to obtain propagule sources from adult mother plants of all species, presenting a gradual increase in the evaluated characteristics over time. Also, in vitro culture is an effective alternative to improve the propagation of the evaluated species, with an establishment of up to 62.5%. However, for Corymbia citriodora (Hook.) K.D. Hill & L.A.S Johnson and Eucalyptus tereticornis Smith it is necessary to develop further studies to enable the in vitro establishment.

Como a seleção e a clonagem de indivíduos superiores geralmente são realizadas na fase adulta, o desenvolvimento e a adequação de técnicas de propagação vegetativa que possibilitem o resgate e o estabelecimento in vitro de espécies desses gêneros são necessários. Dessa forma, o presente estudo teve como objetivo induzir brotos epicórmicos a partir de ramos podados de árvores adultas e promover o estabelecimento in vitro de nove espécies, sendo seis do gênero Eucalyptus e três de Corymbia. O material utilizado para a obtenção dos explantes foi proveniente da seleção de duas matrizes de cada espécie com 44 anos de idade, oriundas da implantação de um teste de espécies e procedências. Foram avaliados o número de gemas e brotos de cada ramo aos 15, 25, 35 e 45 dias após o início do experimento em casa de vegetação. De acordo com os resultados, a indução de brotações epicórmicas a partir de ramos podados foi considerada uma técnica viável e eficiente para obter fontes de propágulos de matrizes adultas de todas as espécies, apresentando um aumento gradual das características avaliadas ao longo do tempo. Além disso, o cultivo in vitro é uma alternativa eficaz para estabelecer propágulos a partir de brotações epicórmicas de árvores adultas da maioria das espécies avaliadas, com estabelecimento de até 62,5%. Contudo, para Corymbia citriodora (Hook.) K.D. Hill & L.A.S Johnson e Eucalyptus tereticornis Smith é necessário o desenvolvimento de mais estudos para viabilizar o estabelecimento in vitro.Sociedade de Investigações Florestais - UFV2021-08-20T19:01:01Z2021-08-20T19:01:01Z2020-12info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfAVELAR, M.
