Resumo: | http://dx.doi.org/10.5902/1980509815721The present work aimed to accomplish the histological analysis of the events involved in the adventitious rooting pattern of four Eucalyptus grandis x Eucalyptus urophylla clones. The mini-cuttings were collected from a mini-stump and the rooting experiments were set up under mini-hedge indoor semi-hydroponics by means of intermittent flooding fertirrigation. For histological analyses, the proximal ends of the mini-cuttings were collected after 0, 1, 2, 4, 6, 8, 10, and 12 days after planting them at greenhouse. After fixation with FAA70%, the samples were dehydrated in a graded ethanol series and infiltrated overnight in metracrilate resin, and finally embedded in resin. It was verified the endogenous origin of adventitious root primordia from vascular cambium, and in some cases, the formation and proliferation of calli at the proximal end of the mini-cuttings within 8 to 12 days. |

As miniestacas foram coletadas de minicepas estabelecidas em minijardim clonal, conduzido em sistema semi-hidropônico em canaletas com fertirrigação. Para a caracterização histológica do processo de rizogênese das miniestacas foram coletadas amostras teciduais aos 0, 1, 2, 4, 6, 8, 10 e 12 dias após o estaqueamento em casa de vegetação climatizada, para enraizamento. As amostras foram fixadas em FAA70%, desidratadas em série etílica e incluídas em metacrilato. Os resultados revelaram a origem endógena de primórdios radiculares a partir do câmbio vascular e, em alguns casos, a proliferação e a formação de uma massa de células desorganizadas (calos) em miniestacas dos clones avaliados, entre 8 e 12 dias de idade.Universidade Federal de Santa Maria2014-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/371910.5902/1980509815721Ciência Florestal; Vol. 24 No. 3 (2014); 521-532Ciência Florestal; v. 24 n. 3 (2014); 521-5321980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3719/pdfGoulart, Patrícia BuenoXavier, AloisioOtoni, Wagner Camposinfo:eu-repo/semantics/openAccess2017-04-12T16:58:19Zoai:ojs.pkp.sfu.ca:article/15721Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-12T16:58:19Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
