Chl Index of leaves of O. basilicum plants cultivated under white light (control—black bars) and supplemental UV-B radiation (UV-B—gray bars) extracted immediately at the end of the light treatment (before storage T_S0) or after seven days of storage (T_S7). Mean ± SD (n = 3). Letters show the comparison between different storage times (T_S0 or T_S7) under the same light conditions (uppercase gray letters—UV-B treatment; lowercase black letters—control). Different letters indicate significant differences between the values (p < 0.05), while asterisks show the significant differences between light treatments at the same time of storage; ns = not significant.
