Fig. 2. A - Variation in reduced (AsA) and oxidized ascorbate (DHA), B - AsA redox state (AsA/DHA), C - reduced (GSH) and oxidized glutathione (GSSG), and D - and glutathione redox potential (GSH/GSSG) in leaves of O. europaea plants under control conditions and exposed to UV-B treatments (UV–B1 and UV-B2). Values are mean ± s.d. (n = 6–8). For each parameter, different letters indicate statistical differences between treatments (P
