Resumo: The objective of this work was to assess the effect of spacing on the growth, biomass allocation, and wood quality for energy purposes of Acacia magium. A randomized complete block design was carried out with three replicates and five treatments consisting of trees planted at different spacings: 2.0x2.0, 2.5x2.5, 3.0x2.0, 3.0x2.5, and 3.0x3.0 m. At 67 months after planting, the following species parameters were evaluated:  performance (mortality, diameter growth, height, bark factor, and bark and biomass volume yield) and wood energy quality (basic density, higher-calorific value, ash, fixed carbon, and volatile materials) through the analysis of variance. Plant spacing did not affect volume and biomass production per hectare nor wood quality for energy purposes. The widest spacing (3.0x3.0 m) provides better individual growth, and the narrowest one (2.0x2.0 m) produces smaller trees, but with the highest percentage of dry biomass in the trunk, and can show the best energy potential at a rotation age from 40 to 50 months.

O experimento foi instalado em delineamento experimental de blocos ao acaso, com três repetições e cinco tratamentos que consistiram de árvores plantadas nos espaçamentos de: 2,0x2,0, 2,5x2,5, 3,0x2,0, 3,0x2,5 e 3,0x3,0 m. Aos 67 meses de plantio, avaliaram-se os seguintes parâmetros da espécie: desempenho (mortalidade, crescimento em diâmetro, altura, fator de casca, e produção volumétrica de casca e de biomassa) e qualidade energética da madeira (densidade básica, poder calorífico superior, cinzas, carbono fixo e materiais voláteis), por meio de análise de variância. O espaçamento de plantio não teve influência sobre a produção em volume e de biomassa por hectare, nem sobre a qualidade da madeira para a produção de energia. O maior espaçamento de plantio (3,0x3,0 m) fornece maior crescimento individual, e o menor espaçamento (2,0x2,0 m) produz árvores de menores dimensões, porém com maior percentagem de biomassa concentrada no tronco, e pode apresentar maior eficiência energética com a adoção de uma idade de rotação entre 40 a 50 meses.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFIT Manejo Florestal Ltda.Tonini, HelioSchwengber, Dalton RobertoMorales, Marina MouraMagalhaes, Ciro Augusto de Souzade Oliveira, Jane Maria Franco2018-10-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/25872Pesquisa Agropecuaria Brasileira; v.53, n.7, jul. 2018; 791-799Pesquisa Agropecuária Brasileira; v.53, n.7, jul. 2018; 791-7991678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/25872/14228https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/25872/17566Direitos autorais 2018 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2018-10-09T16:25:54Zoai:ojs.seer.sct.embrapa.br:article/25872Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2018-10-09T16:25:54Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
