“…The enrichment of underground parts of plants, such as the roots of carrots or potato tubers with I or Se, is possible because of the transportation of these elements through the phloem from the leaves to underground tissues. This effect was demonstrated in studies on biofortification with I in the cultivation of carrots (Signore et al, 2018) and potatoes (Ledwożyw-Smoleń et al, 2020), as well as in research on biofortification with Se in carrots (Oliveira et al, 2018) and potatoes (Zhang et al, 2019). There are no data on whether the foliar application of I and Se simultaneously will enrich carrot roots.…”

Iodine (I) and selenium (Se) are essential to human and animal development. There is a worldwide deficit of I and Se in the diet of humans, as well as in animals. It is advisable to enrich plants with these elements to ensure adequate uptake in animals and humans. The aim of this study was to determine the efficacy of the application of I and Se in the cultivation of carrot crops, to better understand the metabolic pathways and processes of I applied through foliar spray. Carrots were fertilized with 4-fold foliar applications of I and Se, which were applied as the liquid fertilizers “I + Se”, “Solo iodine” and “Solo selenium”, all containing an organic stabilizer, in two field trials. Foliar nutrient applications of I and Se were translocated by the plant for storage in the roots. The level of enriched I and Se in the roots was considered safe for the consumer. The Recommended Daily Allowance values for I and Se in the roots of 100 g of fresh carrots are 4.16% and 4.37%, respectively. Furthermore, I and Se accumulated in the roots to a level that was physiologically tolerated by carrot. Biofortification through foliar feeding did not impact negatively on the yield or quality of the carrot crop. Iodides applied via foliar application were the dominant form of I in the plant tissues and were included in the metabolic process of the synthesis of iodosalicylates, iodobenzoates, iodotyrosine (I-Tyr), and plant-derived thyroid hormone analogs. No synergistic or antagonistic interaction between I and Se, with respect to the effectiveness of biofortification in roots, was observed in any treatments. The molar ratio of I:Se in the roots after foliar application of both elements was approximately 1.6:1 and was similar to the control (1.35:1).

“…On the contrary, high dose decreases crop yield since it acts as a lipid pro-oxidant and increases free radical production causing oxidative stress Zieba et al, 2020). In general, plant response to Selenium differs according to the applied concentration (Puccinelli et al, 2017), species sensitivity (Lyons, 2018), chemical species used and form of application, which is why the optimum dose for each crop should be determined (Ramos et al, 2010;Oliveira et al, 2018). In hydroponic tomato, the recommended dose for Se is 1.27 mg L -1 to avoid phytotoxicity (Edelstein, 2016).…”

Selenium (Se) is an essential element for humans. Its consumption comes from food of animal or vegetal origin; whose content varies widely depending on its availability in soil or anthropogenic sources. Biofortification improves food nutritional quality, and its consumption has a positive influence in human health. Thus, the objective of this research was to assess agricultural biofortification with Se in tomato fruit and its effects on yield, nutraceutical quality, and antioxidant capacity. Five Se doses (0, 2, 4, 6, and 8 mg L-1) in the form of sodium selenite (Na2SeO3) were added in a nutritional solution in a hydroponic system. The results obtained indicated that agricultural biofortification with Se applied in the nutritional solution improved yield, nutraceutical quality, and Se concentration in tomato fruit. The optimum Se dose that maximized yield and nutraceutical quality, as well as the recommended consumption concentration in tomato fruit in this study was 2 mg L-1 (Na2SeO4) because higher doses decreased yield and bioactive compound biosynthesis. Incorporating Se in the nutritional solution is an alternative to increase phytochemical compound biosynthesis in tomato fruit and yield with the possibility of improving public health with its consumption.
