Abstract

We determined an optimal combination of preharvest UV irradiation and postharvest storage conditions of temperature and low light irradiation for increasing the concentration and content of functional compounds in komatsuna (Brassica rapa var. perviridis ‘Inamura’). The plants were cultivated hydroponically under white fluorescent lamps for 21 d after sowing (DAS) and then exposed to UV-B (3.0 W m^‑2) or no irradiation for 3 d during the light period as pre-harvest treatments.
As postharvest treatments, UV-irradiated or non-irradiated plants with six leaves were enclosed in plastic bags and stored at 5 or 10°C (postharvest treatments 1: Cont._T5, Cont._T10, UV_T5, and UV_T10), or those enclosed in plastic bags stored at 5°C were exposed to white fluorescent light in an incubator controlled at PPFD levels of 0,10, and 20 µmol m^‑2 s^‑1 for 7 d (postharvest treatment 2: Cont._P0, Cont._ P10, Cont._P20, UV_P0, UV_P10, and UV_P20). The results showed that UV irradiation of komatsuna at 3.0 W m^‑2 before harvest increased the concentration of functional compounds (total polyphenol concentration and antioxidant capacity) without growth inhibition.
The combination of preharvest UV irradiation and post-harvest storage at 5°C increased the concentrations of chlorophyll and total polyphenols in plants.
Furthermore, the combination of preharvest UV irradiation and postharvest storage under PPFD 10 µmol m^‑2 s^‑1 mitigated the reduction in fresh and dry weight, chlorophyll, ascorbic acid, and anthocyanin concentrations, and increased total polyphenol concentrations and antioxidant capacity, resulting in an improved appearance and quality of the vegetable as a functional food.
