Resumo: The aim of this study was to evaluate the relationship between biometric variables quantified along the phenological development of the wheat crop with grain yield and production components. The study was carried out in an area of 4.7 ha. Initially the area was georeferenced and divided into a sampling grid of 50 x 50 m, resulting in 18 sample points. At each point three subplots of 2 x 1 m were marked. The emergency of plants seven days after emergence (DAE) (stage 1), number of plants, number of tillers, number of leaves per plant, root length, height, root dry mass, dry mass of the aerial part and number of nodes at 35 (stage 5), 57 (stage 8) and 80 (stage 10.3) DAE were evaluated. The yield component was determined regarding the number of spikes; 1000 grain weight; number of grains per spike and grain yield at 130 DAE (stage 11.4). Biometric differences in wheat plants from phenological stage 8 affect the productive components of crop. Wheat plants higher (height and number of nodes) and reduced root length showed higher productivity.

O estudo foi realizado em uma área de 4,7 ha. Inicialmente a área foi georreferenciada e dividida em uma malha amostral de 50 x 50 m, resultando em 18 pontos amostrais. Em cada ponto amostral foram demarcadas três subparcelas de 2 x 1 m. Foi avaliado a emergência de plântulas aos 7 dias após a emergência (DAE) (estádio 1), número de plantas, número de afilhos, número de folhas por planta, comprimento radicular, altura, massa seca radicular, massa seca da parte aérea e número de nós aos 35 (estádio 5), 57 (estádio 8) e 80 (estádio 10,3) DAE. Os componentes produtivos número de espigas, peso de 1.000 grãos, número de grãos por espiga e produtividade foram quantificados aos 130 DAE (estádio 11,4). Diferenças biométricas em plantas de trigo a partir do estádio fenológico 8 afetaram os componentes produtivos da cultura. Plantas de trigo com elevada estatura (altura e número de nós) e reduzido comprimento radicular apresentaram maiores produtividades.Universidade do Estado de Santa Catarina2016-11-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.udesc.br/index.php/agroveterinaria/article/view/22381171153201622710.5965/223811711532016227Revista de Ciências Agroveterinárias; Vol. 15 No. 3 (2016); 227-236Revista de Ciências Agroveterinárias; v. 15 n. 3 (2016); 227-2362238-1171reponame:Revista de Ciências Agroveterinárias (Online)instname:Universidade do Estado de Santa Catarina (UDESC)instacron:UDESCporhttps://periodicos.udesc.br/index.php/agroveterinaria/article/view/223811711532016227/pdf_44Pias, Osmar Henrique de CastroDamian, Júnior MeloCherubin, Maurício RobertoSanti, Antônio Luisinfo:eu-repo/semantics/openAccess2019-12-13T12:05:24Zoai::article/7986Revistahttps://periodicos.udesc.br/index.php/agroveterinaria/PUBhttps://periodicos.udesc.br/index.php/agroveterinaria/oairca.cav@udesc.br | portal.periodicos@udesc.brhttps://doi.org/10.5965/223811712238-11711676-9732opendoar:2019-12-13T12:05:24Revista de Ciências Agroveterinárias (Online) - Universidade do Estado de Santa Catarina (UDESC)false
