Iodine and Selenium Biofortification of Chervil Plants Treated with Silicon Nanoparticles.

Production of functional food with high levels of selenium (Se) and iodine (I) obtained via plant biofortification shows significant difficulties due to the complex interaction between the two elements. Taking into account the known beneficial effect of silicon (Si) on plant growth and development, single and joint foliar biofortification of chervil plants with potassium iodide (150 mg L) and sodium selenate (10 mg L) was carried out in a pot experiment with and without Si nanoparticles foliar supplementation. Compared to control plants, nano-Si (14 mg L) increased shoot biomass in all treatments: by 4.
