Resumo: Studies that address the appropriate use of forest resources are essential for the management and conservation of forest remnants, such as the Araucaria Forest. Considering the importance to improve the knowledge of the tree species growth in subtropical regions, the present study aimed to assess the intra-annual diameter growth of tree species in Colombo County, Paraná State, Brazil. In November 2009 dendrometer bands were installed in adult trees (15 to 25 trees) of 9 species among the most frequent in the studied Araucaria Forest remnant. The increment in diameter were measured monthly until June 2011. Ocotea bicolor grew faster and more constant than the other species. This may be due to lower coverage of the trees canopies, making easier to O. bicolor trees to access light and consequently resulting in improvement in growth. The highest growth of all species occurred in Fall of 2011, season preceded by a Winter of low rainfall (2010`s Winter), in which the sun light was more available for the photosynthetic production.

Tendo em vista a necessidade de se aprimorar conhecimentos sobre o crescimento de espécies em regiões subtropicais, o presente trabalho teve por objetivo monitorar o crescimento diamétrico intra-anual de espécies arbóreas em Colombo, Paraná. Em novembro de 2009 foram instaladas faixas dendrométricas em árvores adultas (de 15 a 25 indivíduos) de 9 espécies dentre as mais frequentes em um remanescente de Floresta Ombrófila Mista. As medições de incremento diamétrico foram feitas mensalmente, até junho de 2011. Ocotea bicolor se diferenciou das outras espécies, apresentando crescimento superior e constante. Isto pode ser atribuído ao menor recobrimento da copa das árvores, favorecendo o acesso à luz pela espécie e consequentemente o seu crescimento. O maior crescimento de todas as espécies estudadas ocorreu no outono de 2011, estação antecedida por um inverno de baixa precipitação (inverno de 2010), em que a luminosidade esteve mais disponível para a produção fotossintética.Embrapa Florestas2014-04-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/60210.4336/2014.pfb.34.77.602Pesquisa Florestal Brasileira; v. 34 n. 77 (2014): jan./mar.; 31-37Pesquisa Florestal Brasileira; Vol. 34 No. 77 (2014): jan./mar.; 31-371983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/602/354Canetti, AlineRuy, Camila CastillaMattos, Patricia Povoa deBraz, Evaldo Muñozinfo:eu-repo/semantics/openAccess2017-04-28T12:47:45Zoai:pfb.cnpf.embrapa.br/pfb:article/602Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T12:47:45Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
