“…Various studies reported that Se can control the photosynthesis antenna complex, defending chlorophylls by increasing the levels of photosynthetic pigments. It is possible that the advantages of Se in photosynthesis are related to the interaction of the Fe–S complex in chloroplasts since they play a crucial role in the electron transport chain and ensure that the high excitations of electronic levels have enough substrates to maintain the level of organization . Earlier reports demonstrated that the application of Se can encourage a restructuring of the antenna complex to increase the energy uptake and protect it from oxidative stress .…”

“…Notably, carotenoids, functioning as nonenzymatic antioxidants to counteract the formation of ROS by chloroplasts and peroxisomes, were not affected by Se due to the presence of selenate. Khan et al 43 stated that the presence of selenate could enhance the production of carotenoids, while the selenite form promotes the production of chlorophyll b. In this case, the joint effect of both forms of Se used could have altered the chlorophyll content but maintained the carotenoid levels in this type of plants.…”

The impact of selenium (Se) enrichment on bioactive compounds and sugars and Se speciation was assessed on different microgreens (green pea, red radish, and alfalfa). Sodium selenite and sodium selenate at a total concentration of 20 μM (1:1) lead to a noticeable Se biofortification (40−90 mg Se kg −1 DW). In green pea and alfalfa, Se did not negatively impact phenolics and antioxidant capacity, while in red radish, a significant decrease was found. Regarding photosynthetic parameters, Se notably increased the level of chlorophylls and carotenoids in green pea, decreased chlorophyll levels in alfalfa, and had no effect on red radish. Se treatment significantly increased sugar levels in green pea and alfalfa but not in red radish. Red radish had the highest Se amino acid content (59%), followed by alfalfa (34%) and green pea (28%). These findings suggest that Se-biofortified microgreens have the potential as functional foods to improve Se intake in humans.

“…The higher limit of Se intake for adults has been set at 400 μg day −1 33 . There are several geographical areas where the Se in soil is limited and can lead to the production of agricultural foods that lack this element 34 . In the human diet, the Se is better absorbed if incorporated in organic molecules, compared with a mineral Se supplement 35 .…”

BACKGROUND Biofortification of vegetables is an important innovation technique in the horticultural sector. Vegetables can be a vector of different minor elements that have beneficial effects on human health. Selenium (Se) is an important element for human nutrition and plays a significant role in defence mechanisms. The aim of this work was to investigate the effect of Se in the nutrient solutions on the crop biofortification ability, yield, and quality parameters of four baby leafy vegetables destined to the minimally processed industry. Experiments were performed on lamb's lettuce, lettuce, wild rocket, and spinach. These crops were cultivated in the floating systems with nutrient solution enriched with 0, 2.6, 3.9, and 5.2 μmol L−1 Se provided as sodium selenate. RESULTS At harvest, Se concentrations, yield, nitrate concentration, sugars, and some mineral elements were measured. Data collected and analyses showed that yield, nitrate, sucrose, and reducing sugars were not affected by Se treatments, even if varied among species. Se concentrations linearly increased in leaves of different species by increasing the Se concentration in the nutrient solution. Rocket was the species with the highest accumulation ability and reached a concentration of 11 μg g−1 fresh weight Se in plants grown with 5.2 μmol L−1 Se. CONCLUSION A floating system with Se‐enriched nutrient solution is an optimal controlled growing biofortification system for leafy vegetables. The accumulation ability decreased in different species in the order wild rocket, spinach, lettuce, and lamb's lettuce, highlighting a crop‐dependent behaviour and their attitude to biofortification. © 2023 The Authors.
