Resumo: An experiment was conducted at the EEA/UFRGS, located in Guaíba, Rio Grande do Sul State, Brazil, during 1984/85, to study the effects of two planting dating dates (8.10.84 and 11.1.85) on leaf development (leaves number, size, area and appearance rates) of three maize (Zea mays L)cultivars (Agroceres 280, Cargill 408, Pioneer 6872). As planting was delayed plant leaf area was little affected and some of the variations, according to the genotype, was due to leaf number (decreased in Agroceres 28C and Cargill 408), expansion (increased in Agroceres 28C and Pioneer 6872) and senescence. The plant leaf area profile was not affected by genotype or planting date. The biggest leaves were located around the ear insertion node. Leaves number was higher in the late cultivars and maximum leaf area occurred at silking stage.

O objetivo do trabalho foi avaliar o efeito de duas datas de plantio (8.10.84 e 11.1.85) no desenvolvimento foliar (número, taxa de emissão, tamanho de folha e área foliar) de três cultivares de milho (Zea mays L.) (Agroceres 28C, Cargill 408 e Pioneer 6872). A área foliar por planta foi pouco afetada com o retardamento da época de plantio e as modificações que ocorreram foram dependentes do genótipo e decorrentes de variações no número de folhas (reduzido para as cultivares Agroceres 28C e Cargill 408), expansão foliar (aumentada nas cultivares Agroceres 28C e Pioneer 6872) e senescência foliar. O perfil da área foliar na planta não variou com o genótipo e a época, sendo que as maiores folhas estavam em torno da espiga superior. O número de folhas por planta foi maior nos genótipos de maior ciclo e a máxima área foliar ocorreu nos estádios de espigamento médio e antese.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraNoldin, José AlbertoMundstock, Claudio Mario2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14270Pesquisa Agropecuaria Brasileira; v.22, n.2, fev. 1987; 187-193Pesquisa Agropecuária Brasileira; v.22, n.2, fev. 1987; 187-1931678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14270/8189info:eu-repo/semantics/openAccess2014-09-26T18:13:33Zoai:ojs.seer.sct.embrapa.br:article/14270Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-26T18:13:33Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
