Resumo: The objective of this work was to evaluate the effect of age, time of the year and cut height on the resprouting capacity of Acacia mearnsii De Wild. stumps. The work was conducted in stands of four and seven years of age, in randomized blocks design and time subdivided plots. Different cut heights (0.15; 0.30; 0.45; 0.60; 1.2 and 2 m), and evaluation times (15, 30, 45, 60, 75 and 90 days after cutting), in the four seasons of the year were evaluated. A significant interaction between cut height and evaluation time was found in both ages. The higher averages due to stumps in each strain were verified in 1.2 and 2 m height, in the age of four years. High death percentages were registered in seven years-old stumps, independently of cut height. The resprouting capacity of black wattle stumps is stimulated when cut is conducted between autumn and spring; summer is the least suitable season to stumps resprouting of this specie.

O trabalho foi conduzido em delineamento de blocos ao acaso e parcelas subdivididas no tempo. Em árvores de quatro e sete anos, foram avaliadas as alturas de corte de 0,15; 0,30; 0,45; 0,60; 1,2 e 2 m aos 15, 30, 45, 60, 75 e 90 dias depois do corte, nas quatro estações do ano. Obteve-se interação significativa entre a altura de corte e a época de avaliação, em ambas as idades avaliadas. As maiores médias, quanto ao número de brotações por cepa, foram constatadas a 1,2 e 2 m de altura, na idade de quatro anos. Elevados porcentuais de mortalidade foram registrados em cepas com sete anos, independentemente da altura de corte. A capacidade de rebrota em cepas de acácia-negra é estimulada, quando o corte é realizado no período entre o outono e a primavera. O verão é a estação menos adequada à rebrota de cepas dessa espécie.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPerrando, Edison RogérioCorder, Maisa Pimentel Martins2006-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7174Pesquisa Agropecuaria Brasileira; v.41, n.4, abr. 2006; 555-562Pesquisa Agropecuária Brasileira; v.41, n.4, abr. 2006; 555-5621678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7174/4219info:eu-repo/semantics/openAccess2010-11-09T15:46:50Zoai:ojs.seer.sct.embrapa.br:article/7174Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-11-09T15:46:50Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
