Abstract. Wavelength-selective absorption of solar radiation
within plant leaves allows penetration of visible radiation (400-700
nm) to the chloroplasts, while removing much of the damaging ultraviolet-B
(UV-B, 280-320 nm) radiation. Flavonoids are important in this
wavelength-selective absorption. Induction of flavonoid synthesis
by solar radiation, and specifically by UV-B radiation, is discussed
as this relates to the potential acclimation of plants to enhanced
solar UV-B radiation that would result from stratospheric ozone
