(A) Appearance of sweet basil plants over 72 h, after low and high UV-B exposures and control (Ctrl) condition (not UV-B exposed); (B) Leaf disks of sweet basil cv. Genovese irradiated with low UV-B light (30 min: 8.5 kJ m⁻² day⁻¹), high UV-B light (4hours: 68 kJ m⁻² day⁻¹) or not UV-B exposed (control). Cell death was monitored by staining the leaves with Evans blue after 72 h from the beginning of exposure. The pattern presented is representative of at least 10 replicates.
