This study was conducted to examine the effects of seed presoaking on bioactive phytochemicals in barley and wheat microgreens grown under two different growing media, i.e., hydroponics and organic soil. Microgreens were cultivated for 12 days in a plant growth chamber consistent with the following: light-dark interval (12/12 hours), light-dark temperature (20/15°C), light intensity (150 μmol‧m–2‧s–1), and relative humidity (60%). Both wheat and barley microgreens grown in organic soil from presoaked seeds showed increased levels of bioactive compounds, especially carotenoids, flavonoids, phenolics, total vitamin C, and anthocyanins. Antioxidant activities [2,2-diphenyl-1-picrylhydrazyl, 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity, nitrite scavenging activity, and superoxide dismutase (SOD)-like activity] and antioxidant enzymes (catalase activity, glutathione reductase, and guaiacol peroxidase activity) were highest in both barley and wheat microgreens grown in organic soil from pre-soaked seeds.
