Resumo: An experiment was conducted during 1978/79 at the Universidade Federal do Rio Grande do Sul (UFRS) Agronomy Experimental Station, in Guaíba, RS, Brazil, study the maize (Zea mays L.) ear and tassel development as affected by interplant competition. Increase in competition (10, 20, 40, 80 and 160.000 plants/ha) antecipated tassel differentiation (except at the highest population), but ear differentiation and development were delayed. The top three ears' dry weight was reduced by competition from the time of ear differentiation up to final harvest.

O aumento da competição (10, 20, 40, 80 e 160.000 plantas/ha) antecipou a diferenciação do pendão (exceto na maior população de plantas), mas a diferenciação e desenvolvimento das espigas foram atrasados. O peso seco das três espigas superiores foi reduzido pela competição desde a diferenciação até o final do ciclo.  Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSantos, Henrique Pereira dosMundstock, Claudio Mario2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15459Pesquisa Agropecuaria Brasileira; v.18, n.11, nov. 1983; 1181 -1185Pesquisa Agropecuária Brasileira; v.18, n.11, nov. 1983; 1181 -11851678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15459/9384info:eu-repo/semantics/openAccess2014-04-16T18:43:23Zoai:ojs.seer.sct.embrapa.br:article/15459Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:43:23Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
