Methodologies for the Accelerated Aging Test in Triticale Seeds
Triticale is a Poaceae widely used in the southeastern region of Brazil in the winter period. However, the seeds of this species may have low vigor as consequence of exposure to adverse factors, either biotic or abiotic, during their formation. This means that the evaluation of the vigor is essential to estimate the physiological potential of the seed lots destined to the cultivation of this forage. The objective of this work was to evaluate the methodology of the accelerated aging test to determine the physiological potential of triticale seeds. We determined the percentage of moisture, percentage and seedling emergence speed, and percent germination before and after accelerated aging, which was performed using water, saturated saline solution, and unsaturated saline solution for 48, 72 and 96 hours at 42 ° C. The interpretation of the results allowed us to conclude that the accelerated aging test for 48 hours with saline solution, saturated or not, is efficient to evaluate the vigor of triticale seeds.

El triticale es una Poaceae ampliamente usada en la región sureste de Brasil en el periodo de invierno. Sin embargo, las semillas de esta especie pueden presentar bajo vigor por exposición a factores adversos, ya sea bióticos o abióticos, durante su formación. Esto hace que la evaluación del vigor sea imprescindible para estimar el potencial fisiológico de los lotes de semillas destinados al cultivo de esta forrajera. El objetivo del trabajo fue evaluar la metodología del ensayo de envejecimiento acelerado para determinar el potencial fisiológico de semillas de triticale. Se determinaron el porcentaje de humedad, el porcentaje y velocidad de emergencia de plántulas y el porcentaje de germinación antes y después del envejecimiento acelerado, que fue realizado usando agua, solución salina saturada y solución salina no saturada durante 48, 72 y 96 horas a 42 °C. La interpretación de los resultados permitió concluir que el ensayo de envejecimiento acelerado durante 48 horas con solución salina, saturada o no, es eficiente para evaluar el vigor de semillas de triticale.
