Resumo: The accelerated aging test is a possible option for evaluation of seeds vigor, however there is not enough information on your efficiency for forest seeds, as of Dalbergia nigra (Vell.) Fr. All. This study was conducted to investigate procedures to assess seed vigor by the accelerated aging test in seed forest, of Dalbergia nigra. For so much, an experiment was realized at Laboratory of Analysis of Seeds, in Universidad Federal of Paraíba, in Areia - PB, Brazil Northeast. Accelerated aging was performed at 41°C during 24, 48, 72 and 96 hours. Seeds were kept in plastic boxes with 40mL of distilled water in a B.O.D chamber. Seeds were tested for germination and moisture content before and after aging. The aging at both temperatures (41 ° C and 45 ° C) after 72 hours, affect the physiological quality of seeds of Dalbergia nigra (Vell.) Fr All., promoting reduction of viability and vigor.

Fr. All. (jacarandá-da-bahia). Foi conduzido experimento no Laboratório de Análise de Sementes, da Universidade Federal da Paraíba, com o objetivo de avaliar a qualidade fisiologia de sementes de D. nigra por meio do teste de envelhecimento acelerado. O teste foi conduzido a 41 e 45°C durante 24, 48, 72 e 96 horas, além da testemunha (sementes não envelhecidas). Realizou-se o teste de emergência das plântulas em campo, para verificar a qualidade fisiológica das sementes. As sementes foram distribuídas em camada única sobre tela, em caixas plásticas com 40 mL de água destilada, no interior de câmara BOD. O teor de água e a germinação o vigor das sementes foram determinados antes e após o envelhecimento. O envelhecimento em ambas as temperaturas (41°C e 45°C) a partir de 72 horas, afeta a qualidade fisiológica de sementes de Dalbergia nigra (Vell.) Fr. All., promovendo redução da viabilidade e do vigor.UEL2011-07-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/324710.5433/1679-0359.2011v32n2p443Semina: Ciências Agrárias; Vol. 32 No. 2 (2011); 443-450Semina: Ciências Agrárias; v. 32 n. 2 (2011); 443-4501679-03591676-546Xreponame:Semina.
