Resumo: | Chia (Salvia hispanica L.) is a plant native to central and western Mexico and northern Guatemala belonging to the Lamiaceae family, well known for its seeds containing antioxidants, dietary fibers, and ?-linolenic acid, which helps to prevent different diseases, such as diabetes, obesity, cancer and Alzheimer. In Brazil, there is not much information about the crop, mainly about the physiological quality of its seeds. Therefore, the objective was to establish vigor testing methods to evaluate the physiological quality of chia seeds. Five seed lots were used, in which germination tests, seedling emergence, emergence velocity index and variations in the electrical conductivity test were carried out. The volume of distilled water was 25 and 50 mL, the number of seeds was 50 and 100, the temperature was 20, 25 and 30 °C, the soaking period was 1, 2, 4, 6, 12, 18 and 24 hours and variations in there was accelerated aging test by the traditional method and saturated NaCl solution, being periods of aging as 24, 48, 72 and 96 hours and temperatures of 38, 41 and 44 °C. It is concluded that both the electrical conductivity test and the accelerated aging test are efficient in evaluating the physiological quality of chia seeds. The electrical conductivity test must be performed with 100 seeds in 50 mL of distilled water, for four hours soaking at 25 or 30 °C; and the accelerated aging test should be performed at 44 °C for 24 hours by the traditional method or 41 °C for 24 hours using saturated NaCl solution. |

No Brasil, não há muitas informações a respeito da cultura, principalmente sobre qualidade fisiológica de sementes. Sendo assim, o objetivo foi estabelecer metodologia de testes de vigor para avaliar a qualidade fisiológica de sementes de chia. Foram utilizados cinco lotes de sementes, nos quais foram realizados os testes de germinação, emergência de plântulas, índice de velocidade de emergência e variações no teste de condutividade elétrica, sendo volume de água destilada: 25 e 50 mL, quantidade de sementes: 50 e 100, temperatura: 20, 25 e 30 °C e período de embebição: 1, 2, 4, 6, 12, 18 e 24 horas e variações no teste de envelhecimento acelerado pelo método tradicional e solução saturada de NaCl, sendo períodos de envelhecimento: 24, 48, 72 e 96 horas e temperaturas: 38, 41 e 44 ºC. Conclui-se que tanto o teste de condutividade elétrica quanto o de envelhecimento acelerado são eficientes na avaliação da qualidade fisiológica de sementes de chia. O teste de condutividade elétrica deve ser realizado com 100 sementes em 50 mL de água destilada, pelo período de quatro horas de embebição, à 25 ou 30 °C; e o teste de envelhecimento acelerado deve ser realizado à 44 °C por 24 horas pelo método tradicional ou 41 °C por 24 horas utilizando solução saturada de NaCl.UEL2019-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionarticleapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3418010.5433/1679-0359.2019v40n6Supl2p2891Semina: Ciências Agrárias; Vol. 40 No. 6Supl2 (2019); 2891-2904Semina: Ciências Agrárias; v. 40 n. 6Supl2 (2019); 2891-29041679-03591676-546Xreponame:Semina.
