Resumo: | The objective of this work was to determine the appropriate time to prune the terminal portions of the cotton plants. The work was carried out during 2008 and 2009 (May–November) growing seasons in a randomized block design in two environment, with the varieties: BRS 201, of white fibers, and the colored fiber varieties BRS Rubi, BRS Safira, and BRS Verde, in Paudalho, PE, Brazil; and BRS 201 and BRS Rubi, in Surubim, PE, Brazil. Pruning consisted in excising the apices with the vegetative and reproductive structures, at two plant ages: with 50% mature bolls (prune I), and at the opening of the first boll (prune II). Prune I resulted in greater excision of flower buds than prune II. In both prunings, five nodes from the plant apex were excised. Yield and fiber quality did not differ between pruned and nonpruned plants. A significant number of infested structures was removed by pruning. Pruning can be recommended to reduce nonproductive structures that can, at the end of the season, be used as hosts for important pests. |

O trabalho foi realizado durante as safras de 2008 e 2009 (maio a novembro) em delineamento de blocos ao acaso, em dois ambientes, com as variedades: BRS 201, de fibra branca, e BRS Rubi, BRS Safira e BRS Verde, de fibra colorida, em Paudalho, PE; e BRS 201 e BRS Rubi, em Surubim, PE. A poda apical consistiu na retirada dos ápices das plantas com estruturas vegetativas e reprodutivas, em duas idades fenológicas: com 50% das maçãs maduras (poda I) e no surgimento dos primeiros capulhos (poda II). A poda I resultou em maior retirada de botões florais do que a poda II. Em ambas as podas, houve a retirada de cinco nós dos ponteiros. A produção e a qualidade de fibra não diferiram entre plantas podadas ou não. Um número significativo de estruturas atacadas foi eliminado pela poda. A poda apical é recomendada para reduzir o número de estruturas não produtivas, ao final da safra, que são utilizadas como hospedeiras de pragasPesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFACEPE, CNPq, FINEPNeves, Robério Carlos dos SantosTorres, Jorge Brazda Silva, Melchior Naelson Batista2011-03-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/8098Pesquisa Agropecuaria Brasileira; v.45, n.12, dez. 2010; 1342-1350Pesquisa Agropecuária Brasileira; v.45, n.12, dez. 2010; 1342-13501678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/8098/6153https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/8098/3697info:eu-repo/semantics/openAccess2014-11-14T16:37:11Zoai:ojs.seer.sct.embrapa.br:article/8098Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-14T16:37:11Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
