Resumo: There is currently great interest in the cultivation of the Jatropha curcas L., known locally as physic nut, for the production of biodiesel, leading to an increase in the demand for seeds and precise information as to their physiological quality, especially vigour. The objective was to evaluate the efficiency of the accelerated ageing test, with variations, in verifying the vigour of Jatropha seeds. Four seed lots were initially characterized as to their physiological quality by germination and vigour tests. For accelerated ageing test, temperatures of 42 and 45 oC were tested during 48, 72 and 96 hours. The experiment was carried out in a completely randomized design and the averages of the treatments compared by Tukey test (p<0,05). The Pearson correlation coefficients for the results of accelerated ageing against results from the other tests were calculated. The accelerated ageing test at 42 or 45 oC for 48 hours is efficient to classify Jatropha seed lots according to vigour level.

Objetivou-se avaliar a eficiência do teste de envelhecimento acelerado, com variações, para a verificação do vigor de sementes de pinhão manso. Sementes de quatro lotes foram incialmente caracterizadas quanto à qualidade fisiológica pelos testes de germinação e de vigor. Para a realização do teste de envelhecimento acelerado, foram testadas as temperaturas de 42 e 45 oC, por 48; 72 e 96 horas. O experimento foi conduzido em delineamento inteiramente casualizado e as médias dos tratamentos comparadas pelo teste de Tukey (p<0,05). Foram calculados os coeficientes de correlação de Pearson entre os resultados de envelhecimento acelerado e os dos demais testes. O teste de envelhecimento acelerado a 42 ou 45 oC por 48 horas, é eficiente para classificar lotes de sementes de pinhão manso em níveis de vigor.Revista Ciência Agronômica2018-02-22T17:27:33Z2018-02-22T17:27:33Z2013-10-08info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf18066690http://dx.doi.org/10.1590/S1806-66902014000100015http://www.locus.ufv.br/handle/123456789/17842engv. 45, n. 1, p. 120-127, Janeiro-Março 2014Dias, Luiz Antônio dos SantosOliveira, Glauter LimaDias, Denise Cunha Fernandes dos SantosSoares, Marcos MoraisSilva, Laércio Junio dainfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T06:42:18Zoai:locus.ufv.br:123456789/17842Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T06:42:18LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
