Effects of Individual and Simultaneous Selenium and Iodine Biofortification of Baby-Leaf Lettuce Plants Grown in Two Different Hydroponic Systems

The iodine (I) and selenium (Se) deficiencies affect approximately 30% 15%, respectively, of the global population. biofortification vegetables is a valid way to increase intake through diet. This study was carried out on baby-leaf lettuce investigate effects plant growth, leaf quality, I Se accumulation adding potassium iodide sodium selenate, separately simultaneously, nutrient solution in floating system aeroponics. effect post-harvest quality leaves also evaluated. Our results evidenced that treatments increased content two microelements without any negative interactions plants, when applied either or simultaneously. Both hydroponic systems proved be suitable for producing and/or enriched lettuce. Biofortification with more effective performed aeroponics, whereas system. Quality during storage not affected by neither treatments. Lettuce 13 µM 5 µMI could good dietary sources inducing toxic humans.
