Resumo: A fast growth in the use of substances that increase soybean yield through physiological or morphological changes, such as cytokinin, has taken place in recent years. This study aimed at assessing the effect of the application time of cytokinin as kinetin on soybean crops. The experiment was carried out under field conditions, using four treatments (control and kinetin at the vegetative stages V4, V6 and V4 + V6), with five replications, in completely randomized blocks. Physiological (nitrate reductase and peroxidase activity, H2O2 content and lipid peroxidation) and phenometric parameters (leaf and root dry mass), as well as yield, were evaluated. The application of kinetin at V4, V6 or V4 + V6 increased the activity of the nitrate reductase enzyme and reduced stress (evaluated via lipid peroxidation and hydrogen peroxide content), in addition to raising the dry matter content. All these characteristics resulted in increased yield. However, the most significant effects were caused by the application of kinetin at V6, which increased yield  in 20 %, in relation to the control.

Objetivou-se avaliar o efeito da época de aplicação de citocinina na forma de cinetina, na cultura da soja. O experimento foi realizado em condições de campo, utilizando-se quatro tratamentos (controle e cinetina nos estágios vegetativos V4, V6 e V4 + V6), com cinco repetições, em blocos inteiramente casualizados. Foram realizadas avaliações fisiológicas (atividade de nitrato redutase e peroxidase, teor de H2O2 e peroxidação de lipídios) e fenométricas (massa de matéria seca de raiz e folhas), além da produtividade. A aplicação de cinetina em V4, V6 ou V4 + V6 proporcionou incremento na atividade da enzima nitrato redutase, redução do estresse (avaliado por meio da peroxidação lipídica e teor de peróxido de hidrogênio) e aumento no teor de massa de matéria seca. Todas essas características repercutiram no aumento da produtividade. Contudo, os efeitos mais expressivos foram causados pela aplicação de cinetina em V6, que proporcionou incremento de 20 % na produtividade, em relação ao controle.Escola de Agronomia - Universidade Federal de Goiás2017-04-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/42790Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 47, n. 1, Jan./Mar. 2017; 80-86Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 47, n. 1, jan./mar. 2017; 80-86Pesquisa Agropecuária Tropical; v. 47, n. 1, jan./mar. 2017; 80-861983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/42790/22758Copyright (c) 2017 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessSoares, Luís HenriqueDourado Neto, DurvalFagan, Evandro BinottoTeixeira, Walquíria FernandaPereira, Isabella Sabrina2020-07-13T18:28:57Zoai:ojs.revistas.ufg.br:article/42790Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:15.078214Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
