Criteria for implementation of a tetrazolium test in canola seeds

Abstract: -Canola is an oilseed winter plant, constituting an alternative to crop rotation. It presents socioeconomic value for the production of vegetable oil for human consumption, biodiesel and animal food formulation. The evaluation of canola seed viability is routinely performed by germination test, which can be extended for up to 14 days if it is necessary to overcome dormancy. The objective of this study was to establish criteria for conducting a tetrazolium test in canola seeds, determining viability groups. Fou… Show more

“…Similar results indicating the need to remove the seed coat were also obtained by Barros et al (2005) in zucchini. However, in seeds of forage turnip (Nery et al, 2015), canola (Flores et al, 2015) and carrot (Lima et al, 2018), the longitudinal cut along the longest axis before immersion in the tetrazolium solution was the most indicated.…”

“…Therefore, this concentration was eliminated from the subsequent tests. Several authors (Rezende et al, 2015;Flores et al, 2015;Nery et al, 2015) reported difficulty in interpreting the test when the seeds were exposed to a concentration of 1.0%, because they showed a very intense red staining. This fact brought challenges to the interpretation of the test, especially when associated with prolonged times of exposure.…”

“…Realizar el pretratamiento con hipoclorito de sodio o agua destilada, empleando una concentración 0,15 % de la solución y un tiempo de exposición de 24 horas en semillas de tomate, permite generar información sobre la calidad de la semilla, revelando aspectos importantes de un lote de semillas ya sea para su conservación o para su siembra (Duarte et al, 2017); además, emplear semillas de alta calidad en la siembra del cultivo asegura una rápida germinación y emergencia, así como uniformidad de las plántulas en el lote (Faber et al, 2015).…”

“…Las semillas son el soporte de la industria agrícola (Zhang et al, 2018); por lo tanto, generar información sobre la calidad de la semilla es de gran importancia para asegurar una rápida germinación y uniformidad de las plantas en campo (Faber et al, 2015), y para la conservación en bancos de germoplasma (Al-Hammad & Al-Ammari, 2017). Debido a la gran importancia de este parámetro (calidad de la semilla), se han desarrollado diversos métodos; para ello, incluso se ha implementado espectroscopia de infrarrojo cercano (Shrestha et al, 2017).…”
