Resumo: | Growth analysis of soybean plants treated with plant growth regulators. This work aimed to verify the effect of plant growth regulators on soybean plant growth and chlorophyll content. In an experiment carriedout in a greenhouse, soybean plants were cultivated (Glycine max (L.) Merrill cv. BRS-184) in 10-liter pots containing soil from the arable layer, corrected and fertilized according to the soil analysis. The treatments used were: control; GA3 100mg.L-1; BAP 100mg.L-1; IBA 100mg.L-1; Stimulate® (IBA, GA3 and kinetin) 20mL.L-1; mepiquat chloride 100mg.L-1 and mepiquat chloride 100mg.L-1 + BAP 100mg.L-1 + IBA 100mg.L-1. Treatments were applied three times at 30-day intervals. Six samplings were taken at 13-day intervals. The results indicated that the highest total dry weight value resulted from the application of IBA and Stimulate®, and that the applicationof mepiquat chloride in association with IBA and BAP reduced total dry matter production. The leaf area was smaller than the control in most treatments. The chlorophyll content and growth rate were slightly infl uenced by the treatments. The cytokinin treatment alone or in association with other plant growth regulators retained the chlorophyll content. RGR and NAR decreased from 99 days after sowing with the application of mepiquat chloride. |

Merrill cv. BRS-184) e conteúdo de clorofila. Em experimento instalado em casa-de-vegetação, plantas de soja (Glycine max (L.) Merrill cv. BRS-184) foram cultivadas em vasos de 10L, com terra da camada arável corrigida e adubada conforme a análise do solo. Foram avaliados sete tratamentos: testemunha; GA3 100mg.L-1; BAP 100mg.L-1; IBA 100mg.L-1; Stimulate (IBA, GA3 e Cinetina) 20mL.L-1; cloreto de mepiquat 100mg.L-1 e cloreto de mepiquat 100mg.L-1 associado a BAP 100mg.L-1 + IBA 100mg.L-1, os quais foram aplicados três vezes a intervalos de 30 dias e realizadas seis avaliações a intervalos de 13 dias. Os resultados revelaram que a maior produção de massa seca total ocorreu com a aplicação de IBA, Stimulate e cloreto de mepiquat. A área foliar foi inferior à testemunha na maioria dos tratamentos; o teor de clorofi la e a taxa de crescimento forampouco influenciados pelos tratamentos. O tratamento com citocinina isolada ou associada a outros reguladores manteve por mais tempo o teor de clorofila. A TCR e a TAL foram reduzidas a partir dos 99 dias após a semeaduracom aplicação de cloreto de mepiquat.Universidade Federal de Santa Catarina2011-09-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2008v21n3p5310.5007/2175-7925.2008v21n3p53Biotemas; v. 21 n. 3 (2008); 53-632175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2008v21n3p53/18846Copyright (c) 2008 Marcelo Ferraz de Campos, Elizabeth Orika Ono, Carmen Silvia Fernandes Boaro, João Domingos Rodriguesinfo:eu-repo/semantics/openAccessCampos, Marcelo Ferraz deOno, Elizabeth OrikaBoaro, Carmen Silvia FernandesRodrigues, João Domingos2022-11-21T14:14:58Zoai:periodicos.ufsc.br:article/20738Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2022-11-21T14:14:58Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
