Resumo: | The physic nut has been considered as one of the oilseed plants species with the highest potential for biofuel production. Oleaginous seeds demand special care during storage to maintain their quality. This study aimed to establish the most adequate conditions for their storage. Freshly-harvested seeds were dried until 7.2 moisture content and stored along a year, under the following conditions: environmental laboratory and cold chamber ( ±5 ºC and 60% RH), into paper bag, polypropylene bag, and cardboard barrel. Physiological quality was then assessed by the tests: germination; first count; germination speed index; seedling length; accelerated aging; cold test; field emergence; and emergence speed index, after zero, three, six, nine, and 12 months. There was linear reduction of germination and vigor of the seeds after storage under environmental laboratory condition, into paper or polypropylene bags, and cardboard barrel. Physiological quality was higher after storage in cold chamber, into paper or polypropylene bags; and into cardboard barrel, at environmental laboratory condition. |

Sementes ricas em óleo demandam maior cuidado para a sua preservação durante o armazenamento. O objetivo deste trabalho foi estabelecer as condições mais adequadas para o armazenamento das sementes de pinhão manso. Sementes recém-colhidas foram secas até o teor de umidade de 7,2% e armazenadas, ao longo de um ano, nas seguintes condições: ambiente de laboratório e câmara fria (±5 ºC e 60% UR), em sacos de papel kraft, polipropileno trançado e em tambor de papelão.A qualidade fisiológica foi então avaliada pelos testes de: germinação; primeira contagem; índice de velocidade de germinação; comprimento de plântula; envelhecimento acelerado; teste de frio; emergência; e índice de velocidade de emergência, após zero, três, seis, nove e 12 meses. Houve redução linear da germinação e do vigor das sementes após armazenamento em ambiente natural, em saco de papel kraft, polipropileno trançado e tambor de papelão. A qualidade fisiológica das sementes foi maior após armazenamento em câmara fria, em embalagens de papel Kraft, polipropileno trançado; e tambor de papelão, em ambiente de laboratório.Journal of Seed Science2019-06-28T13:42:55Z2019-06-28T13:42:55Z2013info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf2317-1545http://dx.doi.org/10.1590/S2317-15372013000100003http://locus.ufv.br//handle/123456789/25975engv. 35, n. 01, p. 21- 27, 2013Dias, Denise Cunha Fernandes dos SantosPereira, Márcio DiasBorges, Eduardo Euclydes de Lima eMartins Filho, SebastiãoDias, Luiz Antônio dos SantosSoriano, Paulo Emídioinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T07:20:49Zoai:locus.ufv.br:123456789/25975Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T07:20:49LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
