Representative distributions of average radiation interception and phenolic compound contents on individual leaves of kales under the control and UV-B treatments (n = 3). PAR, photosynthetically active radiation in the range of 400–700 nm; UV, biological effective UV radiation in the range of 280–400 nm. The color var indicates each range of 0–200 μmol m⁻² s⁻¹ for PAR interception, 0–10 kJ m⁻² d⁻¹ for UV radiation interception, 0–12 mg CE g⁻¹ DW for flavonoids and 0–16 mg GAE g⁻¹ DW for phenolic compounds.
