Resumo: Jatropha curcas L. is an oleaginous plant that has distinguished itself by presenting the qualities necessary to the biodiesel production. This study aimed to adjust the accelerated aging test methodology to evaluate the physiological potential of Jatropha curcas seeds. For this, four seeds lots were initially characterized by water content, germination percentage and first counting, seedlings emergence percentage and speed index, low temperature germination, and shoot height. The treatments included three temperatures (41ºC, 42ºC, and 45ºC) and four seeds exposure times (24, 48, 72, and 96 hours), in about 100% relative humidity. The accelerated aging test carried out for 24 hours, at 41ºC, was efficient for evaluating the Jatropha curcas vigour seeds, allowing to classify lots according to vigour levels, similarly to the germination first counting tests, seedlings emergence, low temperature germination, emergence speed index, and shoots height.

O objetivo deste trabalho foi adequar a metodologia do teste de envelhecimento acelerado, para a avaliação do potencial fisiológico de sementes de pinhão-manso. Para isto, quatro lotes de sementes foram, inicialmente, caracterizados, por meio do teor de água, percentagem e primeira contagem de germinação, percentagem e índice de velocidade de emergência de plântulas, germinação a baixa temperatura e altura da parte aérea. Os tratamentos utilizados foram três temperaturas (41ºC, 42ºC e 45ºC) e quatro tempos de exposição das sementes (24, 48, 72 e 96 horas), em cerca de 100% de umidade relativa do ar. O teste de envelhecimento acelerado conduzido por 24 horas, a 41ºC, foi eficiente para avaliar o vigor de sementes de pinhão-manso, permitindo a classificação dos lotes em níveis de vigor, à semelhança dos testes de primeira contagem de germinação, emergência de plântulas, germinação a baixa temperatura, índice de velocidade de emergência e altura da parte aérea de plântulas.Escola de Agronomia - Universidade Federal de Goiás2012-03-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/12175Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 42, n. 1, Jan./Mar. 2012; 119-123Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 42, n. 1, jan./mar. 2012; 119-123Pesquisa Agropecuária Tropical; v. 42, n. 1, jan./mar. 2012; 119-1231983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/12175/10544Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessPereira, Márcio DiasFilho, Sebastião MartinsLaviola, Bruno Galvêas2020-07-10T11:12:48Zoai:ojs.revistas.ufg.br:article/12175Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:50.683880Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
