Resumo: The aim of this work was to evaluate the differences in seed physiological quality of four Palmae species submitted to accelerated aging. After harvest, the seeds of each species were exposed to accelerated aging (45ºC and 100% R.U.) during 0 (control), 12, 24, 36 and 48 hours. Euterpe edulis and Dypsis lutescens were sensible to accelerated aging and germination process was inhibited after 12 hours inside the camara. Roystonea oleracea and Phoenix reclinata were more tolerant than the other species, but exibited gradual decrease on seed vigor, as the time inside the camara increased. The critical period for some vigor parameters evaluated was 48 hours inside the camara.

Sementes recém-colhidas de cada uma das espécies foram expostas às condições de envelhecimento acelerado em câmara a 45ºC e 100% de UR, durante os períodos de 0 (controle), 12, 24, 36 e 48 horas. Sementes de Euterpe edulis e Dypsis lutescens foram sensíveis ao tratamento, sendo a germinação totalmente suprimida após 12 horas de permanência na câmara. As espécies Roystonea oleracea e Phoenix reclinata apresentaram sementes mais resistentes que as outras espécies, mas redução gradativa do vigor, de acordo com o aumento do período de exposição às condições de envelhecimento; o período de 48 horas foi crítico para determinados parâmetros de vigor avaliados.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraNegreiros, Gisele de Freitasde Andrade Perez, Sonia Cristina Juliano Gualtieri2004-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6785Pesquisa Agropecuaria Brasileira; v.39, n.4, abr. 2004; 391-396Pesquisa Agropecuária Brasileira; v.39, n.4, abr. 2004; 391-3961678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6785/3841info:eu-repo/semantics/openAccess2014-07-16T19:21:43Zoai:ojs.seer.sct.embrapa.br:article/6785Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-16T19:21:43Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
