Selênio no condicionamento fisiológico de sementes e na biofortificação de microverdes de lentilha

Abstract

The lentil is a legume that is widely grown and consumed throughout the world, and is of great economic importance and a nutritional source. Priming stands out for being a practical, fast and low-cost technique, offering several advantages for farmers who do not have advanced equipment, providing an effective alternative for increasing seedling vigor and productivity In this study, we investigated the hypothesis that the application of selenium (Se) through combined priming would be an effective approach to improve physiological responses, resulting in better productivity and quality of lentil seeds and microgreens, being evaluated two Se sources (Na2SeO4 and Na2SeO3) at five concentrations (0; 1; 5; 10 and 20 mg L-1) of the "BRS Mimi" variety. As far as we know, this is the first application of this seed conditioning technique with Se for this cultivar, which could support its greater integration in the fight against nutritional deficiencies, especially in the context of hidden hunger caused by unbalanced diets. Previous studies indicate that this approach can be effective in improving the germination performance of seeds and microgreens. Osmopriming and osmopriming with selenate are promising strategies for enhancing seed viability, with osmopriming using selenite being effective for the biofortification of lentil microgreens.
