“…The addition of Se fertilizers to the soil is an appropriate way to biofortify high amounts of foodstuffs and to increase the Se content in soils that have a low selenium content [ 61 , 75 , 76 , 77 , 78 ]. However, high amounts of Se need to be applied to the soil to obtain Se plant concentrations equal to other fertilization methods [ 49 , 79 ].…”

“…Selenium spraying has been used to enhance the Se content in potatoes [ 83 ], rice [ 84 ], soybeans [ 85 ], buckwheat and pumpkins [ 86 ], garlic [ 87 ], carrots [ 88 ], broccoli [ 89 ], cabbages [ 76 ], radishes [ 90 ], basil [ 91 , 92 , 93 , 94 ], tomatoes [ 44 , 95 ], peaches and pears [ 40 ], and grapes [ 96 ]. Results of spraying depend on the characteristics of the leaf and fruit surface, such as the presence of hairs, the characteristics of the epicarp, the chemical composition of the epicuticular wax, or the deposition of wax platelets [ 40 ].…”

The ability of some crops to accumulate selenium (Se) is crucial for human nutrition and health. Selenium has been identified as a cofactor of the enzyme glutathione peroxidase, which is a catalyzer in the reduction of peroxides that can damage cells and tissues, and can act as an antioxidant. Plants are the first link in the food chain, which ends with humans. Increasing the Se quantity in plant products, including leafy and fruity vegetables, and fruit crops, without exceeding the toxic threshold, is thus a good way to increase animal and human Se intake, with positive effects on long-term health. In many Se-enriched plants, most Se is in its major organic form. Given that this form is more available to humans and more efficient in increasing the selenium content than inorganic forms, the consumption of Se-enriched plants appears to be beneficial. An antioxidant effect of Se has been detected in Se-enriched vegetables and fruit crops due to an improved antioxidative status and to a reduced biosynthesis of ethylene, which is the hormone with a primary role in plant senescence and fruit ripening. This thus highlights the possible positive effect of Se in preserving a longer shelf-life and longer-lasting quality.

“…Selenium has a significant impact on growth and quality of vegetables. Addition of selenium significantly increases Se content in spinach [ 5 ], broccoli [ 6 ], cabbages [ 7 ], radishes [ 8 ], generally without negatively affecting the biomass and quality of plants. Selenium promotes metabolic activities, particularly antioxidant activities, enhancing plant tolerance under unfavorable growth conditions [ 9 ].…”

Selenium (Se) supplement was combined with different LED light qualities to investigate mutual effects on the growth, nutritional quality, contents of glucosinolates and mineral elements in broccoli sprouts. There were five treatments: CK:1R1B1G, 1R1B1G+Se (100 μmol L−1 Na2SeO3), 1R1B+Se, 1R2B+Se, 2R1B+Se, 60 μmol m−2 s−1 PPFD, 12 h/12 h (light/dark). Sprouts under a combination of selenium and LED light quality treatment exhibited no remarkable change fresh weight, but had a shorter hypocotyl length, lower moisture content and heavier dry weight, especially with 1R2B+Se treatment. The contents of carotenoid, soluble protein, soluble sugar, vitamin C, total flavonoids, total polyphenol and contents of total glucosinolates and organic Se were dramatically improved through the combination of Se and LED light quality. Moreover, heat map and principal component analysis showed that broccoli sprouts under 1R2B+Se treatment had higher nutritional quality and health-promoting compound contents than other treatments. This suggests that the Se supplement under suitable LED lights might be beneficial to selenium-biofortified broccoli sprout production.

“…It was possible to notice that mycorrhizal inoculation reduced the accumulation of Se in leaves, but inoculated plants had higher contents of minerals, proteins and/or sugars than the non-inoculated controls supplied with Se. Mechora et al 15 studied the effects of selenate foliar spraying on the physiological and biochemical characteristics of cabbage plants. Despite the high concentration of Se used in the foliar solution, there was no effect on photosynthesis, transpiration rate, photochemical efficiency of PSII, or electron transport system activity.…”

The effect of selenate and selenite enrichment on mineral composition of a red type of lettuce cv. "Veneza roxa" was evaluated using inductively coupled plasma-optical emission spectroscopy (ICP OES), molecular modeling and principal component analysis (PCA). Both Se species did not show toxicity, while selenate promoted the greatest Se accumulation by the plant. There was an increase of 886 µg of Se per 100 g of fresh sample at different concentrations of selenate, but for selenite the maximum variation was only of 114 µg per 100 g. Selenate promoted the absorption of Mo and S and the reduction of K, Mn and P, meanwhile selenite increased Mn and decreased Mo accumulation. Copper and Fe absorption was negatively affected, Ca and Mg showed a slight increase, and Na and Zn were not affected by Se species. Despite the changes in the nutritional balance, Se-enriched lettuce can still be considered a potential dietary source of this essential element.
