Resumo: The objective of this work was to evaluate how branch and stem variables contribute to grain yield in individual soybean (Glycine max) plants, cultivated at different planting densities, in a modern cultivar with indeterminate growth type. A field experiment was carried out during the 2013/2014 and 2014/2015 crop seasons, in a randomized complete block design with 12 replicates, using the cultivar NK7059 RR at four planting densities: 135, 235, 315, and 440 thousand plants per hectare. Grain yield per plant was evaluated and represented phenotypic plasticity, while the number of branches per plant, percentage of grain production in branches, and separate yield components from branches and stems were considered as the independent variables. The number of pods in branches per plant was found to be the most important variable for soybean plasticity. In addition, the number of pods per plant on stems, number of branches per plant, and the percentage of grain production in branches were also associated with plasticity. Contrastingly, the number of grains per pod and the mass of a thousand grains in the branches and stems contributed little to plasticity in 'NK7059 RR' soybean.

Um experimento de campo foi realizado nas safras 2013/2014 e 2014/2015, em delineamento de blocos ao acaso, com 12 repetições, tendo-se utilizado a cultivar NK7059 RR, a quatro densidades de plantio: 135, 235, 315 e 440 mil plantas por hectare. A produção de grãos por planta foi avaliada e representou a plasticidade fenotípica, enquanto o número de ramos por planta, a percentagem da produção de grãos oriunda dos ramos e os componentes de rendimento oriundos dos ramos e das hastes, separadamente, foram considerados como variáveis independentes. O número de vagens por planta nos ramos foi a variável mais determinante da plasticidade da soja. Além disso, o número de vagens por planta nas hastes, o número de ramos por planta e a percentagem da produção de grãos oriunda dos ramos também estiveram associados à plasticidade. De forma contrastante, o número de grãos por vagem e a massa de mil grãos nos ramos e nas hastes contribuíram pouco para a plasticidade da soja 'NK7059 RR'.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes)coffee producers Ademir Trevizani, Daniel Trevizani, and Luiz Antônio CovreBalbinot Junior, Alvadi AntonioOliveira, Maria Cristina Neves deFranchini, Julio CezarDebiasi, HenriqueZucareli, ClaudemirFerreira, André SampaioWerner, Flavia2018-11-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/25226Pesquisa Agropecuaria Brasileira; v.53, n.9, set. 2018; 1038-1044Pesquisa Agropecuária Brasileira; v.53, n.9, set. 2018; 1038-10441678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/25226/14287Direitos autorais 2018 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2018-11-07T14:18:37Zoai:ojs.seer.sct.embrapa.br:article/25226Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2018-11-07T14:18:37Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
