Resumo: | Wheat plants use different strategies for achieving grain yield. Among them, one can point out the compensatory mechanisms among the grain yield components: number of ears per unity of area, number of grains per ear and grain weight. Grain yield in wheat is mostly represented by tiller production, providing that plants are adequately spaced from each other and that weather conditions are favorable to stimulate tillering. Thus, it is necessary to understand the different factors that are related to tiller production and development. The signalling pathways and the morphophysiological responses to environmental factors such as light quality, soil fertility and water availability are also important. The correct adjustment of these factors, as presented in this review, is essential for maximizing grain yield. In the breeding programs it is important make efforts to use genotypes with low number of tillers, even with a higher number of seeds per hectare, to maximize grain yield, reducing the dependence on environmental variables. |

As plantas de trigo utilizam estratégias diferenciadas para a composição do rendimento de grãos. Entre elas se destacam os mecanismos compensatórios entre os componentes do rendimento de grãos: espigas por unidade de área, grãos por espiga e massa de grãos. A produção de grãos em trigo é representada, em grande parte, pela produção de afilhos, desde que as plantas estejam suficientemente espaçadas entre si e haja condições climáticas e de manejo adequadas para estimular um adequado afilhamento. Portanto, se faz necessário o entendimento dos diferentes fatores relacionados à produção e desenvolvimento de afilhos, desde o conhecimento das rotas sinalizantes até as respostas morfo-fisiológicas dos genótipos aos fatores de ambiente, principalmente da qualidade da luz, da fertilidade do solo e da disponibilidade hídrica. O ajuste correto desses fatores, conforme abordado nesta revisão, é de fundamental importância para a maximização da produtividade de grãos. Além disto, parece evidente a necessidade de esforços no melhor aproveitamento de genótipos com reduzido número de afilhos, mesmo com um maior gasto de sementes por hectare, buscando-se a maximização em rendimento de grãos e uma menor dependência das variáveis de ambiente.UEL2009-12-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/465810.5433/1679-0359.2009v30n4Sup1p1207Semina: Ciências Agrárias; Vol. 30 No. 4Sup1 (2009); 1207-1218Semina: Ciências Agrárias; v. 30 n. 4Sup1 (2009); 1207-12181679-03591676-546Xreponame:Semina.
