Differential Antioxidant Response to Supplemental UV-B Irradiation and Sunlight in Three Basil Varieties.

ABSTRACT: Three basil plant varieties (Ocimum basilicum var. Genovese, Ocimum × citriodorum, and Ocimum basilicum var. purpurascens) were grown under moderate light (about 300 µmol photons m^-2 s^-1) in a glasshouse or growth chamber and then either transferred to an open field (average daily dose: 29.2 kJ m^-2 d^-1) or additionally exposed to UV-B irradiation in a growth chamber (29.16 kJ m^-2 d^-1), to reveal the variety-specific and light-specific acclimation responses. Total antioxidant capacity (TAC), phenolic profile, ascorbate content, and class III peroxidase (POD) activity were used to determine the antioxidant status of leaves under all four light regimes. Exposure to high solar irradiation at th
