Resumo: The objective of this study was to evaluate the survival and productivity of ministumps in tube system and the effect of indolbutyric acid (IBA) in rooting of Grevillea robusta minicuttings. The experiment was done in Colombo-PR, with ministumps originated from seedlings. These ministumps were cultured in plastic tubes during one year. After 15 collections, ministumps survival was 100% with an average production of 1.7 minicuttings per ministump and 4030 minicuttings per square meter. The rooting results were 83, 79, 75 and 72% for the treatments 0, 1000, 2000 and 4000 mg L-1 of IBA, respectively, being the best results obtained without IBA. Considering these results, it is possible to conclude the minicutting technique of young propagules is an interesting alternative to propagate Grevillea robusta during the whole year and, in addition, it is an important tool on adaptation of protocols for selected adult material.

O presente estudo teve como objetivo avaliar a sobrevivência e a produtividade de minicepas no sistema de tubetes e o efeito do ácido indolbutírico (AIB) no enraizamento de miniestacas de Grevillea robusta. O experimento foi conduzido em Colombo, PR, com minicepas formadas partindo de mudas obtidas de sementes, as quais foram cultivadas no sistema de tubetes, durante o período de um ano. A sobrevivência das minicepas, após 15 coletas, foi de 100% com produtividade média de 1,7 miniestacas por minicepa e 4030 miniestacas por metro quadrado ao ano. As taxas médias de enraizamento foram 83, 79, 75 e 72% para os tratamentos com 0, 1000, 2000 e 4000 mg L-1 de AIB respectivamente, sendo os melhores níveis obtidos sem aplicação exógena de AIB. Com base nesses resultados, conclui-se que a miniestaquia de propágulos juvenis é uma opção para produção de mudas de Grevillea robusta durante o ano inteiro, sem a necessidade de aplicações de reguladores de crescimento, além de ser uma importante ferramenta para adaptação dos protocolos de propagação vegetativa em materiais adultos selecionados.Universidade Federal de Santa Maria2008-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/42910.5902/19805098429Ciência Florestal; Vol. 18 No. 4 (2008); 455-460Ciência Florestal; v. 18 n. 4 (2008); 455-4601980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/429/307Souza Junior, Levi deQuoirin, MargueriteWendling, Ivarinfo:eu-repo/semantics/openAccess2017-05-09T12:08:13Zoai:ojs.pkp.sfu.ca:article/429Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-09T12:08:13Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
