Resumo: | With the objective of analyzing the palm heart tree growth, in lowland areas submitted to the palm heart exploration, aiming to subsidize the rational handling of the species, a study was accomplished in the county of Igarapé-Miri, PA, Brazil. All of the stems and new budding of three plants of different ages (12, 24, 36 and 48 months after heart extraction) were sampled, and the following components were collected for dry matter evaluation: leaflets, rachis + petioles, sheath + palm hearts and trunks. Representative clumps of the population were selected based on the medium height of the trunks, and number of shoots and leaves. The total dry matter production was 2.68, 5.25, 9.23 and 42.91 kg per plant at 12, 24, 36 and 48 months after the palm heart extraction, respectively. In the recently explored palm heart areas the leaflets represented about 40% of the total weight of the aerial part of the plant and the trunks 10%. After 48 months, in recomposed areas, the trunks were responsible for 73% of the total weight of the plant, while the leaflets only for 10%. Twelve months after the cutting of palm heart, the plants presented medium height of 1 m, and reached more than 3 m after 48 months. |

Foram amostrados todos os estipes e rebrotes de três plantas de cada idade após o corte (12, 24, 36 e 48 meses após a extração do palmito), e avaliada a matéria seca dos seguintes componentes: folíolos, ráquis + pecíolos, bainhas + palmitos, e estipes. As plantas selecionadas são representativas da população quanto à altura média dos estipes, número de perfilhos e número de folhas. A produção de matéria seca total foi de 2,68, 5,25, 9,23 e 42,91 kg por planta no 12o, 24o, 36o e 48o mês após a extração do palmito, respectivamente. Nos açaizais recém-explorados, os folíolos representaram cerca de 40% do peso total da parte aérea da planta, e os estipes, 10%. Após 48 meses, em açaizais recompostos, os estipes foram responsáveis por 73% do peso total da parte aérea da planta, e os folíolos, somente por 10%. Doze meses após o corte do palmito, os açaizeiros apresentavam altura média de 1 m, e atingiram mais de 3 m após 48 meses.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraNogueira, Oscar LameiraConceição, Heráclito Eugênio Oliveira da2000-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6008Pesquisa Agropecuaria Brasileira; v.35, n.11, nov. 2000; 2157-2166Pesquisa Agropecuária Brasileira; v.35, n.11, nov. 2000; 2157-21661678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6008/3112info:eu-repo/semantics/openAccess2010-07-29T12:41:52Zoai:ojs.seer.sct.embrapa.br:article/6008Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-29T12:41:52Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
