植物叶片对太阳辐射的波长选择性吸收允许可见辐射（400-700 nm）穿透到叶绿体，同时去除大部分有害的紫外线B（UV-B，280-320 nm）辐射。黄嘌呤在这种波长选择性吸收中很重要。类黄酮合成的诱导太阳辐射，特别是通过UV-B辐射，进行了讨论，因为这涉及到植物的潜在驯化，以增强太阳UV-B辐射，这将导致平流层臭氧减少。
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 reduction.
