Resumo: This study aimed to evaluate, throughout the seasons, the minicutting technique as a cloning method for Eucalyptus benthamii x Eucalyptus dunnii hybrids regarding minicutting survival and rooting. The ministumps of H12, H19 and H20 clones were cultivated during 352 days in a clonal minigarden in a semi-hydroponic system in a sand bed, where the nutritive solution was supplied by drip irrigation. During the experiment, 27 successive minicutting samplings were performed in 4 seasons of the year: spring, summer, autumn and winter. The minicutting basal portion was immersed in hydro-alcoholic solutions containing 2,000 mg L-1 of IBA during 10 seconds. The experiment was conducted using an entirely randomized design with 5 replications and 20 minicuttings per replication. The minicutting rooting varied in function of the clone and presented high sensitivity to seasonal and temperature variations. The best rooting indices occurred in the cooler seasons (19.59% to 56.20%) and the lowest in warmer seasons (4.62% to 8.50%). The H19 and H20 clones presented the greater indices for rooting in all 4 seasons.

As minicepas dos clones H12, H19 e H20 foram manejadas durante 352 dias em minijardim clonal sob sistema semi-hidropônico em leito de areia com solução nutritiva fornecida por gotejamento, efetuando-se 27 coletas sucessivas de brotações durante as quatro estações do ano (primavera, verão, outono e inverno). Mergulhou-se a porção basal da miniestaca durante 10 segundos em solução hidroalcoólica (1:1 v/v) de concentração de 2.000 mg L-1 de AIB. O experimento foi conduzido em delineamento inteiramente casualizado contendo cinco repetições e vinte miniestacas por repetição. O enraizamento das miniestacas variou conforme o clone e mostrou-se muito sensível às estações do ano e às oscilações da temperatura. Os melhores índices de enraizamento foram registrados nas estações mais frias onde variou de 19,59% a 56,20% e os menores nas estações mais quentes, com 4,62% a 8,50%. Os clones H19 e H20 apresentaram os maiores índices de enraizamento nas quatro estações do ano.Universidade Federal de Santa Maria2010-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/206010.5902/198050982060Ciência Florestal; Vol. 20 No. 3 (2010); 453-465Ciência Florestal; v. 20 n. 3 (2010); 453-4651980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2060/1261Brondani, Gilvano EblingWendling, IvarGrossi, FernandoDutra, Leonardo FerreiraAraujo, Marla Alessandrainfo:eu-repo/semantics/openAccess2017-05-05T10:56:19Zoai:ojs.pkp.sfu.ca:article/2060Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-05T10:56:19Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
