Resumo: | Sapindus saponaria L. (Sapindaceae) is a species native to Brazil used in the recovery of degraded areas and has medicinal properties, but the dormancy of its seeds affects negatively the germination and fast obtaining of seedlings. The present study aimed to evaluate the efficiency of different methods for overcoming dormancy of Sapindus saponaria seeds. The treatments to overcome the seeds dormancy were: control – intact seeds; immersion in concentrated sulfuric acid (96% H2SO4 P.A) for 60, 70, 80 and 90 minutes; immersion in concentrated sulfuric acid for 60, 70, 80 and 90 minutes followed by immersion in distilled water at room temperature for 12, 24 and 36 hours; immersion in water at 70 °C for 10 to 15 minutes followed by exposure in a refrigerator (6 °C) for 30 minutes; immersion in water at 70 °C for 10 to 15 minutes followed by exposure in a freezer (-18 °C) for 30 minutes; heat shock by exposing the seeds in a forced air circulation oven regulated at 70 °C for 5, 10 and 15 minutes followed by the transference to refrigerator and freezer for 30 minutes. For comparison between treatments were evaluated emergence percentage, speed and first counting of emergence, shoot length and primary root, dry matter of shoots and roots. The immersion of the seeds in sulfuric acid for 80 minutes followed by imbibition in water for 24 hours is efficient to overcome the dormancy, to accelerate and to promote the emergence and growth of Sapindus saponaria. |

(Sapindaceae) é uma espécie nativa do Brasil utilizada na recuperação de áreas degradadas e detém propriedades medicinais, mas a dormência das suas sementes dificulta a germinação e a obtenção de plântulas de forma rápida. O presente estudo teve por objetivo avaliar a eficiência de diferentes métodos na superação da dormência de sementes de Sapindus saponaria. Os tratamentos para a superação da dormência das sementes foram: testemunha - sementes intactas; imersão em ácido sulfúrico concentrado (H2SO4 96% P.A) por 60, 70, 80 e 90 minutos; imersão em ácido sulfúrico concentrado por 60, 70, 80 e 90 minutos seguido de embebição em água destilada à temperatura ambiente por 12, 24 e 36 horas; imersão em água a 70°C por 10 e 15 minutos seguida de exposição em geladeira (6°C) por 30 minutos; imersão em água a 70°C por 10 e 15 minutos seguida de exposição em freezer (-18°C) por 30 minutos; choque térmico mediante a exposição das sementes em estufa de circulação forçada de ar regulada a 70°C por 5, 10 e 15 minutos seguida de transferência para geladeira e freezer durante 30 minutos. Para fins de comparação entre os tratamentos foram avaliados a porcentagem de emergência, velocidade e primeira contagem de emergência, comprimento de parte aérea e raiz primária, massa seca de parte aérea e raízes. A imersão das sementes em ácido sulfúrico por 80 minutos seguida de embebição em água por 24 horas é eficiente para superar a dormência, acelerar e promover a emergência e crescimento das plântulas de Sapindus saponaria.Universidade Federal de Santa Maria2018-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3337610.5902/1980509833376Ciência Florestal; Vol. 28 No. 3 (2018); 987-996Ciência Florestal; v. 28 n. 3 (2018); 987-9961980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/33376/pdfCopyright (c) 2018 Ciência Florestalinfo:eu-repo/semantics/openAccessSilva, Rosemere dos SantosAlves, Edna UrsulinoBruno, Riselane de Lucena AlcântaraSantos-Moura, Sueli da SilvaCruz, Flávio Ricardo da SilvaUrsulino, Marina Matias2018-10-01T19:30:41Zoai:ojs.pkp.sfu.ca:article/33376Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-10-01T19:30:41Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
