Resumo: Successful seed conservation depends on reducing the metabolism of both the seeds and other associated organisms. The metabolic activity can be analyzed by the respiratory rates but it depends on the developing of methodological protocols. In addition, modified atmosphere has shown some control in respiration when O2 and CO2 concentrations are changed. This work evaluated the effect of changes in O2 and CO2 concentrations on the inhibition of the respiratory metabolism of Eugenia brasiliensis Lam seeds. The results showed that in atmospheres with CO2 concentration between 1.9% and 3.7% it is possible to decrease the metabolism of these seeds. In addition, a model that allows controlling the factors involved in the analysis of respiratory rates in seeds is presented.

Uma das formas de se avaliar a intensidade metabólica é analisando-se as taxas respiratórias, mas há necessidade de se desenvolver protocolos metodológicos para isso. Além disso, atmosfera modificada tem demonstrado algum controle na respiração quando as concentrações de O2 e CO2 são alteradas. Neste trabalho, avaliou-se o efeito da alteração das concentrações de O2 e CO2 do ambiente em que sementes foram armazenadas de maneira a inibir o metabolismo respiratório das sementes de Eugenia brasiliensis Lam. Os resultados demonstraram que em atmosferas com concentração de CO2 entre 1,9% e 3,7% é possível diminuir o metabolismo respiratório dessas sementes. Além disso, é apresentado um modelo que permite controlar os fatores envolvidos na análise das taxas respiratórias em sementes.SciELO PreprintsSciELO PreprintsSciELO Preprints2021-04-13info:eu-repo/semantics/preprintinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://preprints.scielo.org/index.php/scielo/preprint/view/210310.1590/2236-8906-05/2020porhttps://preprints.scielo.org/index.php/scielo/article/view/2103/3483Copyright (c) 2021 Aline Testoni Cécel, Claudio José Barbedohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCécel, Aline Testoni Barbedo, Claudio José reponame:SciELO Preprintsinstname:SciELOinstacron:SCI2021-04-13T02:06:55Zoai:ops.preprints.scielo.org:preprint/2103Servidor de preprintshttps://preprints.scielo.org/index.php/scieloONGhttps://preprints.scielo.org/index.php/scielo/oaiscielo.submission@scielo.orgopendoar:2021-04-13T02:06:55SciELO Preprints - SciELOfalse
