“…In hydroponic tomato, the recommended dose for Se is 1.27 mg L -1 to avoid phytotoxicity (Edelstein, 2016). Nonetheless, this dose depends on the variety used (Zhao et al, 2017). Tomato is not a species that accumulates Se, and a concentration higher than 25 µg of selenium g -1 of dry root and leaf weight is toxic (Edelstein et al, 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.

“…On the contrary, higher concentrations of both forms of Se significantly reduced biomass, where the greatest decline was recorded in treatments with 400 mg/kg of Se (Figure 3B,C). The influence of higher concentrations of Se on biomass reduction has been recorded in numerous plant species, including Lactuca sativa L. [18,73], Sinapis alba L. [74], Oryza sativa [30], T. aestivum L. [75,76], Zea mays L. [77] and Brassica napus L. [28]. Cartes et al [78] investigated the influence of selenate and selenite (0.1, 0.25, 0.50, 0.75, 1, 1.5, 2, 4, 6, 8, and 10 mg/kg) on the dry biomass of 55-day-old Lolium perenne shoots.…”

Selenium (Se) deficiency in human and animal nutrition is primarily due to low levels of Se in soils. It can be prevented by enriching crops, such as wheat, with Se through agronomic biofortification. Although Se is not essential for plants, it shows a dual effect on their metabolism depending on its concentration. This study aimed to elucidate the impact of five different concentrations (0.4, 4, 20, 40, and 400 mg/kg) of selenate and selenite on the oxidative status and antioxidative response of wheat (Triticum aestivum L., cv. Kraljica) shoots and roots. According to morpho-physiological analyses, selenite was found to have a lower toxicity threshold than selenate. The measurement of oxidative stress biomarkers showed that Se did not cause oxidative damage to wheat seedlings due to the activation of detoxification mechanisms at the biochemical level, which depended on the type of tissue, concentration, and form of applied Se. Treatment with 20 mg/kg of selenate can be recommended for wheat seedling biofortification due to a sufficient increase in Se accumulation in shoots without signs of toxicity. These results contribute to a better understanding of wheat seedlings’ physiological and biochemical responses to Se and the development of more effective biofortification strategies.

“…For hydroponically grown tomatoes, the toxicity-threshold value was calculated to be 1.27 mg L −1 [39]. The response to Se treatment depends on tomatoes cultivars [40]; thus, the risk of overdosing is high. On sensitive cultivars, Se could induce distorted protein structure and function, and oxidative stress [41].…”

Plant Biostimulant Effects of Baker’s Yeast Vinasse and Selenium on Tomatoes through Foliar Fertilization

The application of selenium (Se) to tomatoes enhances accumulation of bioactive compounds. The physiological window of Se is very narrow, and Se overdose reduces the yield. Glycine betaine was shown to reduce Se’s negative effects on plants and to potentiate its beneficial effects. In this study, baker’s yeast vinasse (BYV), as an affordable source of glycine betaine, was tested for its interaction with Se in an optimized foliar fertilizer. The application dose was selected after a laboratory experiment, wherein assays on plant height, leaves surfaces, stomatal conductance, and chlorophyll fluorescence were done. The Se and BYV supplemented foliar fertilizers were tested for their effects on accumulation of bioactives in drip-irrigated tomatoes cultivated in a greenhouse. Under laboratory conditions, assays demonstrated Se and BYV induced effects on tomatoes plants. Both the stomatal conductance and photosynthesis efficiency increased compared to a water treated control. The greenhouse experiment demonstrated that BYV and Se addition increases the number of tomato fruits in the “extra” marketable class and enhances the accumulation of ascorbic acid, carotenes, polyphenols, and flavonoids. The effects depend on the composition of the foliar fertilizer, the most significant effects being recorded for the foliar applied product with the highest BYV and nitrogen content.
