- UV B radiation promoted the expression of PAL and resulted in the accumulation of flavonoids in the leaves of spinach and Chinese cabbage. UV－B辐射诱导菠菜和小白菜叶片内苯丙氨酸解氨酶（PAL）活性迅速升高，并导致其体内吸收UV－B的类黄酮化合物大量积累。
- Field experiments performed in Nanjing area show that enhanced UV B radiation causes marked variations in canopy structure of wheat and in turn affects the canopy s light reflectance and absorption. 南京地区小麦田间紫外辐射试验表明,紫外辐射量的增大能显著影响小麦的群体结构,进而影响小麦对紫外辐射的反射与吸收。
