Selenium Biofortification of Three Wild Species, Rumex acetosa L., Plantago coronopus L., and Portulaca oleracea L., Grown as Microgreens

Microgreens of wild herbs are a source healthy compounds. Selenium (Se) biofortification microgreens could help increase the Se content and thus contribute to requirements in humans. We evaluated whether three herbs, Rumex acetosa L., Plantago coronopus Portulaca oleracea were suitable for order obtain products with high nutraceutical value. In first experiment, species enriched Na2SeO4 at 0 1.5 mg L?1, effects on characteristics evaluated. second using P. 0, 1.5, 5, 10 we investigated there was relation between increasing concentrations nutrient solution microgreens. The added taken up by roots accumulated aerial part. exhibited highest ability accumulate selenium, Se-enriched showed chlorophyll flavonoid content. strong correlation concentration growth may enable cultivation targeted resulting Se-biofortified represent new vegetable product value also ensuring sufficient dietary intake Se.
