Resumo: The jenipapo is a native species from Latin America, belonging to the Rubiaceae family and presents great timber value and alimentary, being exploited without conservation strategies. This study aimed to evaluate the water restriction effect, using two methodologies for the Genipa americana L. seeds germination. The first methodology was performed with immersed seeds in polyethylene glycol solutions (PEG 6000) for 18 days at 0.0, -0.1, -0.3, and -0.4 MPa at 20° C, simulating the flooding conditions. After this period, the seeds were disposed to germinate in Petri dishes with germitest paper, blotter paper type, moistened with water. The second methodology used the same osmotic potential, damping the blotter paper type to simulate the fluid restriction. A completely randomized design was used with four replications of 25 seeds. For the immersed seeds in PEG solutions, the potential -0.3 MPa allowed the osmotic conditioning, while the -0.4 MPa interfered in vigor. In imbibed seeds in paper there was a germination reduction, because the time, until potential events were not observed from -0.3 MPa.

O objetivo deste trabalho foi avaliar o efeito da restrição hídrica, por meio de duas metodologias, na germinação de sementes de Genipa americana L. A primeira foi realizada com sementes imersas em soluções de polietilenoglicol (PEG 6000) por 18 dias a 0,0; -0,1; -0,3 e -0,4 MPa à 20ºC, simulando condições de alagamento, e após este período as sementes foram colocadas para germinar em placas de Petri com folhas de papel tipo mata-borrão umedecidas em água. A segunda utilizou os mesmos potenciais osmóticos umedecendo-se os papéis tipo mata-borrão, para simular a restrição hídrica. O delineamento utilizado foi o inteiramente casualizado com 4 repetições de 25 sementes. Para as sementes imersas em soluções de PEG, o potencial -0,3MPa permite condicionamento osmótico, enquanto à -0,4MPa interfere no vigor. Para as sementes embebidas em papel, ocorre redução da germinação em função do tempo, até não se observar eventos para potenciais a partir de -0,3 MPa.Viçosa, MGporSociedade de Investigações FlorestaisRevista ÁrvorePrimingPEGVigorRestrição hídrica em sementes de jenipapo (Genipa americana L.)Water restriction in jenipapo seeds (Genipa americana L.)info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlereponame:Repositório Institucional da UFSinstname:Universidade Federal de Sergipe (UFS)instacron:UFSinfo:eu-repo/semantics/openAccessTEXTRestricaoHidricaSementesGenipapo.pdf.txtRestricaoHidricaSementesGenipapo.pdf.txtExtracted texttext/plain24191https://ri.ufs.br/jspui/bitstream/riufs/11872/3/RestricaoHidricaSementesGenipapo.pdf.txtb0f57547dd253d8e34a8ef03521806adMD53THUMBNAILRestricaoHidricaSementesGenipapo.pdf.jpgRestricaoHidricaSementesGenipapo.pdf.jpgGenerated Thumbnailimage/jpeg1501https://ri.ufs.br/jspui/bitstream/riufs/11872/4/RestricaoHidricaSementesGenipapo.pdf.jpga6a66070d8d22455f85dcbe67ca308c9MD54LICENSElicense.txtlicense.txttext/plain; charset=utf-81475https://ri.ufs.br/jspui/bitstream/riufs/11872/1/license.txt098cbbf65c2c15e1fb2e49c5d306a44cMD51ORIGINALRestricaoHidricaSementesGenipapo.pdfRestricaoHidricaSementesGenipapo.pdfapplication/pdf273957https://ri.ufs.br/jspui/bitstream/riufs/11872/2/RestricaoHidricaSementesGenipapo.pdf187240121f68e1bcbb91b52152b9dbedMD52riufs/118722019-08-30 16:57:06.318oai:ufs.br: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Repositório InstitucionalPUBhttps://ri.ufs.br/oai/requestrepositorio@academico.ufs.bropendoar:2019-08-30T19:57:06Repositório Institucional da UFS - Universidade Federal de Sergipe (UFS)false
