Resumo: | Commercial plantations of Ocotea porosa available for studying are scarce and therefore should be used as a source of information to establish the potential for management of the species in plantations, even if these evaluations were not been held along the stand development. The recovery of the historical growth of these stands to optimize the management plans is possible by dendrochronology and by the analysis of morphometric and dendrometric data. The aim of this study was to use stand analysis tools, combined with the dendrochronological studies, to recover and to systematize the development of unmanaged stands. The study was conducted in an unmanaged stand of Ocotea porosa, with 44 years old in Rio Negro, PR state, in a UFPR station. Growth inferences recovered by dendrochronology and the competition by the application of methodologies such as slenderness rate and crown cover rate showed consistent results in the analysis of population, indicating the need for a first thinning near 12 years old. Due to the small number of sampled trees, the results do not allow any definitive generalization. However, they are consistent to establish an analysis protocol for unmanaged stands of Ocotea porosa or other species. |

A recuperação do histórico do crescimento desses povoamentos para estruturação dos planos de manejo é possível com o uso da técnica da dendrocronologia e a análise de dados dendrométricos e morfométricos. O objetivo desse trabalho foi utilizar ferramentas de análise de povoamentos florestais aliadas aos estudos dendrocronológicos, para recuperar e sistematizar o desenvolvimento de povoamento não manejado. O trabalho foi conduzido em um povoamento não manejado de imbuia, com 44 anos, em Rio Negro - PR, na Estação Experimental da UFPR. Inferências do crescimento recuperado por dendrocronologia, e competição pela aplicação de metodologias como Grau de Esbeltez e de projeção de copa mostraram resultados compatíveis na análise do povoamento, indicando necessidade de primeiro desbaste próximo aos 12 anos. Em função do pequeno número de árvores amostradas, os resultados não permitem generalizações definitivas, entretanto, são consistentes para estabelecer um protocolo para análise de povoamentos não manejados de Ocotea porosa, assim como de outras espécies.Universidade Federal de Santa Maria2015-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1962010.5902/1980509819620Ciência Florestal; Vol. 25 No. 3 (2015); 699-709Ciência Florestal; v. 25 n. 3 (2015); 699-7091980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/19620/11615Santos, Andreia Taborda dosMattos, Patricia Póvoa deBraz, Evaldo MuñozRosot, Nelson Carlosinfo:eu-repo/semantics/openAccess2017-04-10T18:25:35Zoai:ojs.pkp.sfu.ca:article/19620Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-10T18:25:35Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
