Three basil plant varieties (Ocimum basilicum var. Genovese, Ocimum x citriodorum, and Ocimum
basilicum var. purpurascens) were grown under moderate light (about 300 umol 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 the open field resulted in an increase in TAC, total hydroxycinnamic acids (HCAs, especially
caffeic acid), flavonoids, and epidermal UV-absorbing substances in all three varieties, as well as a
two-fold increase in the leaf dry/fresh weight ratio. The supplemental UV-B irradiation induced
pr...eferential accumulation of HCAs (rosmarinic acid) over flavonoids, increased TAC and POD activity,
but decreased the ascorbate content in the leaves, and inhibited the accumulation of epidermal
flavonoids in all basil varieties. Furthermore, characteristic leaf curling and UV-B-induced inhibition
of plant growth were observed in all basil varieties, while a pro-oxidant effect of UV-B was indicated
with H2O2 accumulation in the leaves and spotty leaf browning. The extent of these morphological
changes, and oxidative damage depended on the basil cultivar, implies a genotype-specific tolerance
mechanism to high doses of UV-B irradiation.
