Resumo: | http://dx.doi.org/10.5902/198050985074This study aimed to evaluate, throughout the seasons, the mini-cutting technique as cloning method for Eucalyptus benthamii x Eucalyptus dunnii hybrids regarding to the mini-stumps survival and to the mini-cuttings production. The ministumps of H12, H19 and H20 clones were cultivated during 352 days in a clonal mini-garden under semi-hydroponic system in a sand bed, where the nutritive solution was supplied by drip irrigation. During the experiment, 27 successive mini-cuttings samplings were performed in four seasons of the year: spring, summer, autumn and winter. The experiment was conducted under whole a randomized design with five replications and four mini-stumps per replication. After 27 successive mini-cuttings samplings, the mini-stumps presented high survival percentage (89.68%), which indicated their high longevity as sprouts supply sources. The mini-cuttings production varied in function of the clone and presented a high sensitivity of seasons and temperature variations. The highest mini-cutting production occurred in warmer seasons (spring and summer), with 635.42 until 852.64 mini-cuttings m-2 variation, and the lowest in the cooler seasons (autumn and winter), with 592.38 until 629.36 mini-cuttings m-2 variation. The mini-cutting annual production was 18,934.76; 20,942.27 and 20,748.14 mini-cuttings m-2 year-1 for H12, H19 and H20 clones, respectively. |

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). O experimento foi conduzido no delineamento inteiramente casualizado contendo cinco repetições e quatro minicepas por repetição. As minicepas apresentaram elevado percentual de sobrevivência (89,68%) após 27 coletas sucessivas de brotações, indicando alta longevidade como fontes fornecedoras de propágulos. A produção de miniestaca variou conforme o clone e mostraram-se sensíveis às estações do ano e às oscilações da temperatura. A maior produção ocorreu nas estações consideradas mais quentes (primavera e verão) com variação de 635,42 a 852,64 miniestacas m-2, e a menor nas estações mais frias (outono e inverno) com 592,38 a 629,36 miniestacas m-2. A produção anual de miniestacas foi de 18.934,76; 20.942,27 e 20.748,14 miniestacas m-2 ano-1, respectivamente para os clones H12, H19 e H20.Universidade Federal de Santa Maria2012-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/507510.5902/198050985075Ciência Florestal; Vol. 22 No. 1 (2012); 11-21Ciência Florestal; v. 22 n. 1 (2012); 11-211980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/5075/3120Brondani, Gilvano EblingWendling, IvarGrossi, FernandoDutra, Leonardo FerreiraAraujo, Marla Alessandra deinfo:eu-repo/semantics/openAccess2014-08-28T22:41:43Zoai:ojs.pkp.sfu.ca:article/5075Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2014-08-28T22:41:43Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
