Resumo: | The objective of this work was to simulate leaf appearance in cultivated rice genotypes and in red rice biotypes, by adapting the Wang and Engel model modified by Streck et al. Two experiments were conducted in Santa Maria, Rio Grande do Sul State, Brazil, during 2004/2005 and 2005/2006 growing seasons. Cultivars IRGA 417 and EEA 406, one hybrid, and two red rice biotypes were used. The leaf appearance model was adjusted, using Haun Stage (HS) data from five sowing dates of 2004/2005 growing season, and the model evaluation was performed using HS data from three sowing dates of 2005/2006 growing season. A numerical experiment was also carried out using temperature data occurred during 2003/2004 and 2006/2007 growing seasons, and simulated HS of the cultivated rice genotypes was compared with the red rice biotypes. The model had a good performance, with a root mean square error usually less than one leaf. Main stem leaf emergence was greater in modern genotypes IRGA 417 and hybrid than in the old genotype EEA 406. Leaf emergence is different among distinct red rice biotypes. |

Dois experimentos foram conduzidos em Santa Maria, RS, em 2004/2005 e 2005/2006. Foram utilizadas as cultivares IRGA 417 e EEA 406, um híbrido e dois biótipos de arroz-vermelho. O modelo de aparecimento de folhas foi ajustado para os genótipos usando-se dados de estágio de Haun (HS), de cinco épocas de semeadura, em 2004/2005, e a avaliação do modelo foi feita com dados de HS medidos em três épocas de semeadura, em 2005/2006. Realizou-se também um experimento numérico utilizando-se dados de temperatura de 2003/2004 e de 2006/2007, e comparou-se o HS simulado dos genótipos cultivados em relação aos biótipos de arroz-vermelho. O modelo apresentou bom desempenho para simular o HS com raiz do quadrado médio do erro geralmente menor do que uma folha. A emissão de folhas na haste principal foi maior nos genótipos modernos – IRGA 417 e híbrido – do que no genótipo tradicional EEA 406. A emissão de folhas é diferente em distintos biótipos de arroz-vermelho.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCAPES, CNPqStreck, Nereu AugustoBosco, Leosane CristinaLucas, Dionéia Daiane PitolLago, Isabel2008-10-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/49Pesquisa Agropecuaria Brasileira; v.43, n.5, maio 2008; 559-567Pesquisa Agropecuária Brasileira; v.43, n.5, maio 2008; 559-5671678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/49/5422https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/49/31https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/49/556https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/49/557https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/49/558https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/49/559info:eu-repo/semantics/openAccess2014-06-09T17:08:51Zoai:ojs.seer.sct.embrapa.br:article/49Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-06-09T17:08:51Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
