Resumo: | The propagation of Caryocar brasiliense (pequizeiro) is still little known. This study aimed to evaluate different osmotic conditions with polyethylene glycol (PEG) in the imbibition process and in the germination of pequi seeds, in addition to verifying the electrical conductivity to evaluate the viability of these seeds. The experiment was conducted with freshly dispersed pyrenes and with pyrenes stored for 90 days. The electrical conductivity of the aqueous solution was measured every six hours for up to 48 hours, using five replications with 20 seeds. The extracted seeds were placed in PEG solutions with osmotic potentials: 0.0; −1.0; −2.0; −3.0; −4.0 MPa, monitored at intervals of 12 hours to 60 hours, plus additional treatment with dry seeds without any type of imbibition. The design was completely randomized with four replications of 25 seeds for germination and four replications of ten seeds for monitoring water content during imbibition. Germination percentage, germination speed index (GSI), percentage of dead and live seeds at 40 days were evaluated. In seeds with longer storage time, the electrical conductivity was higher. Treatments that were not submitted to PEG showed higher GSI, lower mortality percentage and higher germination percentage with 40% and 37%, respectively. The electrical conductivity test was adequate. |

Objetivou-se avaliar diferentes condições osmóticas com polietilenoglicol (PEG) no processo de embebição e na germinação de sementes de pequizeiro, além de verificar a condutividade elétrica para avaliar a viabilidade dessas sementes. O experimento foi conduzido com pirênios recém-dispersos e com pirênios armazenados por 90 dias. A condutividade elétrica da solução aquosa foi medida a cada seis horas por até 48 horas, usando cinco repetições com 20 sementes. As sementes extraídas foram colocadas em soluções de PEG com potenciais osmóticos: 0,0; −1,0; −2,0; −3,0; −4,0 MPa, monitorados com intervalo de 12 horas a 60 horas, mais o tratamento adicional com sementes secas sem nenhum tipo de embebição. O delineamento foi inteiramente casualizado com quatro repetições de 25 sementes para germinação e quatro repetições de dez sementes para monitoramento do teor de água durante a embebição. Avaliou-se a porcentagem de germinação, índice de velocidade de germinação (IVG), porcentagem de sementes mortas e vivas aos 40 dias. Nas sementes com maior tempo de armazenamento, a condutividade elétrica foi maior. Os tratamentos que não foram submetidos ao PEG apresentaram maior IVG, menor percentual de mortalidade e maior percentual de germinação com 40% e 37%, respectivamente. O teste de condutividade elétrica foi adequado.Universidade Estadual de Mato Grosso do Sul, Unidade Universitária de Cassilândia2023-07-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicosonline.uems.br/index.php/agrineo/article/view/736210.32404/rean.v10i3.7362Revista de Agricultura Neotropical; v. 10 n. 3 (2023): REVISTA DE AGRICULTURA NEOTROPICAL; e7362REVISTA DE AGRICULTURA NEOTROPICAL; Vol. 10 No. 3 (2023): REVISTA DE AGRICULTURA NEOTROPICAL; e73622358-6303reponame:Revista de Agricultura Neotropicalinstname:Universidade Estadual de Mato Grosso do Sul (UEMS)instacron:UEMSenghttps://periodicosonline.uems.br/index.php/agrineo/article/view/7362/5555https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRocha Lacerda, VanderFraga Pagehú, LeviPego Gonçalves, Armandoda Silva Brandão Junior, DelacyrNascimento Lopes, Paulo Sérgio2023-08-30T15:18:46Zoai:ojs.pkp.sfu.ca:article/7362Revistahttps://periodicosonline.uems.br/index.php/agrineoPUBhttps://periodicosonline.uems.br/index.php/agrineo/oaiagriculturaneotropical@uems.br || wellingthon.junnyor@uems.br2358-63032358-6303opendoar:2023-08-30T15:18:46Revista de Agricultura Neotropical - Universidade Estadual de Mato Grosso do Sul (UEMS)false |
