AZPILCUETA-PEREZ, M.E. et al. Effect of Selenium supply on some attributes and mineral content in bean seed (Phaseolus vulgaris L.). Revista bio ciencias [online]. 2022, vol.9, e1270.  Epub Apr 12, 2024. ISSN 2007-3380.  https://doi.org/10.15741/revbio.09.e1270.

The objective of this study was to evaluate the effect of Selenium on the morphological and physical characteristics, weight, and content of minerals in the bean seeds (Phaseolus vulgaris L.). A randomized complete block experimental design with seven replications was used. The treatments were three chemical formulations of Selenium: sodium selenite (Na2SeO3), selenium dioxide (SeO2) and sodium selenate (Na2SeO4) at three concentrations each one: 5, 10 and 20 mg L-1, more the control (only deionized water). The application of 10 mg L-1 of Na2SeO3 improved the width and length of the grain, with values ​​of 7.22 and 12.68 mm, respectively, and the application 5 mg L-1 of SeO2, improved the thickness and diameter of the grain, with values ​​of 5.04 mm, and 7.68 mm, respectively. Consequently, the weight of 100 seeds was significantly higher when 5 mg L-1 of Na2SeO3 and SeO2 were supply, with values ​​of 30 and 30.99 g, respectively. The Na2SeO3 and SeO2 formulations at concentrations of 5 mg L-1, improved the radius aspect, the volume and surface area of ​​the grain. Finally, the application of SeO2 and Na2SeO3 at concentrations of 10 and 20 mg L-1, moderately increased the content of Ca and Cu, respectively. The Na2SeO3 and SeO2 formulations at dose 5 mg L-1 was the most consistent in showing a better effect in improving the attributes of bean seeds, compared to the Na2SeO4 formulation in any of the concentrations used in this study.
