Resumo: | http://dx.doi.org/10.5902/198050987552The planted forest stands aim to supply the growing demand for wood, especially for the sawing and veneer industries, that exclusively used wood from native forests. The Australian cedar (Toona ciliata) belongs to the family Meliaceae, is the species of interest for this sector. Studies with the Australian cedar propagation have carried out in latest years, mainly involving the use of mini-cuttings due to the need for high quality cuttings. The objectives of this paper were to evaluate the rooting and the productive capacity of Australian cedar mini-strains, managed in lifted seedbeds and 180 cm3 plastic tubes systems. So, two mini-clone gardens were set up. The mini-strains of both gardens were grown from cut-off seedlings originated from seeds. Successive collections of sprouts were carried out to get the mini-cuttings. Afterwards, they remained in the rooting area under intermittent mist. Thirty days later the rooting characteristics of the cuttings originated from both mini-gardens were evaluated. The period of permanence of the cuttings in the gardens was seven-month long. During this period, six collections from the lifted seedbed and four from the plastic tubes were carried out. The mini-strains in the two systems showed 100% of survival rate. At the end of this seven-month period, an increasing tendency of the average number of mini-cutting was found out in both systems. Those from the lifted seedbed showed more productivity than those ones from the tubes. The plants from the mini-cuttings of the tube showed higher number and length of adventitious roots at the end rooting stage. |

O cedro australiano (Toona ciliata), pertencente à família Meliaceae, é uma das espécies de interesse desse setor. Pela necessidade cada vez maior por mudas de alta qualidade, estudos sobre propagação de cedro australiano têm sido realizados nos últimos anos, principalmente envolvendo o uso da miniestaquia. Os objetivos deste trabalho foram avaliar o enraizamento e a capacidade produtiva das minicepas de cedro australiano, manejadas em sistemas de canaletões e em tubetes de 180 cm3. Assim, estabeleceram-se dois minijardins de minicepas formadas a partir de mudas recepadas, produzidas por sementes. Nestes dois sistemas, foram realizadas coletas sucessivas de brotações para confecção de miniestacas, que permaneceram por 30 dias no setor de enraizamento, em câmara com nebulização intermitente. Após este período, foram avaliadas as características do enraizamento das mudas originadas nos dois sistemas de minijardins testados, que foram conduzidos por sete meses e, durante este período, foram realizadas seis coletas no minijardim de canaletão e quatro, no de tubetes. As minicepas dos dois sistemas apresentam 100 % de sobrevivência. Ao final do período observou-se tendência no aumento do número médio de miniestacas em ambos os sistemas. As minicepas do sistema de minijardim em canaletão são mais produtivas que as do sistema conduzido em tubetes. As mudas originadas de miniestacas do sistema de tubetes apresentam maior número e comprimento de raízes adventícias na expedição do setor de enraizamento.Universidade Federal de Santa Maria2012-12-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/755210.5902/198050987552Ciência Florestal; Vol. 22 No. 4 (2012); 703-713Ciência Florestal; v. 22 n. 4 (2012); 703-7131980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/7552/pdfSilva, Mírian Peixoto Soares daBarroso, Deborah GuerraSouza, Juliana Sobreira deFerreira, Daniele de AlvarengaCarneiro, José Geraldo de Araújoinfo:eu-repo/semantics/openAccess2017-04-20T11:05:43Zoai:ojs.pkp.sfu.ca:article/7552Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-20T11:05:43Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
