Resumo: http://dx.doi.org/10.5902/1980509814566The gain reduction of wood biomass in trees has been assigned to root deformations even in the nursery phase. The objective of this work was the evaluation of the root system hydraulic conductivity, gas exchanges and photochemical efficiency of eucalypt clonal cuttings with and without root deformation inductions. The treatments were: 1) operational cuttings without root malformation inductions (grown according to the used methodology of Fibria Cellulose S.A.); 2) root deformation inductions. These inductions did not promote decrease in the root volume. However, the deformations brought reduction of the root system hydraulic conductivity. Lower photosynthetic rates were also observed along the day in the cuttings in the root deformed cuttings. This decreasing rate is connected to stomatal and non stomatal factors.

O objetivo deste trabalho foi avaliar a condutividade hidráulica do sistema radicular, trocas gasosas e a eficiência fotoquímica de mudas clonais de eucalipto com e sem indução de deformações radiculares. Os tratamentos foram: 1 – mudas sem a indução de deformações radiculares (produzidas de acordo com metodologia operacional do viveiro da Fibria Celulose S.A.) e 2 – mudas com indução de deformações radiculares. A indução da deformação radicular não resultou em queda no volume radicular. Contudo, deformações radiculares provocaram redução na condutividade hidráulica do sistema radicular, assim como foram verificadas quedas na taxa fotossintética das mudas ao longo do dia. A queda da taxa fotossintética em mudas com indução de deformações radiculares está associada a fatores estomáticos e não estomáticos.Universidade Federal de Santa Maria2014-06-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1456610.5902/1980509814566Ciência Florestal; Vol. 24 No. 2 (2014); 277-287Ciência Florestal; v. 24 n. 2 (2014); 277-2871980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/14566/pdfFigueiredo, Fábio Afonso Mazzei Moura de AssisCarneiro, José Geraldo de AraújoPenchel, Ricardo MiguelCampostrini, EliemarThiebaut, José Tarcísio de LimaBarroso, Deborah Guerrainfo:eu-repo/semantics/openAccess2017-04-13T11:56:42Zoai:ojs.pkp.sfu.ca:article/14566Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-13T11:56:42Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
