Resumo: This work aimed at defining guidelines for thinning of four native species in pure stands, in Roraima State: Brazil nut tree (Bertholletia excelsa), Andiroba (Carapa guianensis), Ipê-roxo (Tabebuia avellanedae), and Jatobá (Hymenea courbaril). Analyses were made on the relations between main crown morphometric index, and diameter and height growth of these species. Eighty-seven trees were measured, and data taken are: diameter at breast height, total height, crown insertion height and crown diameter. Crown parameters analysis showed diameter and crown area superiority of Brazil nut, which indicates its need of a proper initial spacing and bigger growing space. However, Brazil nut crown was less efficient to maintain the same mean annual diameter increment.

Foi feita a análise das relações entre os principais índices morfométricos da copa e o crescimento em diâmetro e altura; para isso foram medidos o diâmetro à altura do peito, altura total, altura de inserção e diâmetro da copa de 87 árvores. Na análise dos parâmetros de copa, a castanheira-do-brasil demonstrou superioridade em diâmetro e área, o que indica que essa espécie necessita de um maior espaço vital e maiores espaçamentos iniciais; no entanto, sua copa foi menos eficiente em manter um mesmo incremento médio anual em diâmetro.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraTonini, HelioVerde, Marcelo Francia Arco2005-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7005Pesquisa Agropecuaria Brasileira; v.40, n.7, jul. 2005; 633-638Pesquisa Agropecuária Brasileira; v.40, n.7, jul. 2005; 633-6381678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7005/4053info:eu-repo/semantics/openAccess2014-09-22T16:59:43Zoai:ojs.seer.sct.embrapa.br:article/7005Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-22T16:59:43Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
