Resumo: The accelerated aging test is usually used to evaluate seeds vigor and quality. This study aimed to investigate and establish relations among deterioration, physiological changes, and catalase enzyme activity, during the artificial aging process of Pterogyne nitens seeds. So, P. nitens seeds with and without dormancy overcoming, with the application of concentrated sulfuric acid (95-99%), for 10 minutes, were exposed to the accelerated aging test, for 0, 24, 48, and 72 hours, determining the germination percentage, lipids peroxidation, and catalase enzyme activity. The artificial aging process significantly affected the viability and vigor seeds, after a previous dormancy overcoming, with a decrease in germination and catalase enzyme activity and an increase in lipids peroxidation, during the aging process. For seeds that did not overcome dormancy, no relation among artificial aging, physiological changes, and enzyme activity was observed, so that dormancy acts as a protective mechanism for seeds oxidative stress.

O presente trabalho teve como objetivo investigar e estabelecer relações entre a deterioração, alterações fisiológicas e atividade da enzima catalase, durante o envelhecimento artificial de sementes de Pterogyne nitens. Para tanto, sementes de P. nitens sem e com superação da dormência, por meio da aplicação de ácido sulfúrico concentrado (95-99%), durante 10 minutos, foram submetidas ao teste de envelhecimento acelerado, por 0, 24, 48 e 72 horas, determinando-se a percentagem de germinação, peroxidação de lipídios e atividade da enzima catalase. O envelhecimento artificial afetou significativamente a viabilidade e vigor das sementes, após prévia superação da dormência, observando-se decréscimo na germinação e na atividade da enzima catalase e aumento na peroxidação de lipídios, durante o envelhecimento. Nas sementes que não tiveram a dormência superada, não foi observada relação entre o envelhecimento artificial, alterações fisiológicas e atividade da enzima, de forma que a dormência atua como um mecanismo protetor do estresse oxidativo nas sementes.Escola de Agronomia - Universidade Federal de Goiás2012-03-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Experimentalapplication/pdfhttps://revistas.ufg.br/pat/article/view/16497Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 42, n. 1, Jan./Mar. 2012; 71-76Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 42, n. 1, jan./mar. 2012; 71-76Pesquisa Agropecuária Tropical; v. 42, n. 1, jan./mar. 2012; 71-761983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/16497/10439Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessAtaíde, Glauciana da MataFlores, Andressa VasconcelosBorges, Eduardo Euclydes de Lima e2020-07-10T11:09:31Zoai:ojs.revistas.ufg.br:article/16497Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:53.875411Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
