以黄化番茄和普通番茄幼苗为试材，研究UV-B辐射对番茄幼苗生长和光合作用的影响.结果表明：UV-B辐射处理对番茄幼苗株高、茎粗、叶片的抑制作用非常明显，且对叶绿素破坏严重，导致幼苗光合速率降低，类黄酮含量升高10%以上.UV-B处理后两种番茄生长都受到明显抑制，但以黄化苗的变化更为明显，表明黄化番茄幼苗对 UV-B辐射更为敏感.

The effect of UV-B on the growth and photosynthesis in etiolating type and the normal toma-to seedling were studied.The results showed that the plant height,stem diameter and leaf size of the two kinds of tomato seedlings were inhibited by UV-B radiation.The UV-B radiation caused great damage of chlorophyll and decrease in photosynthetic rate (Pn ).The flavonoid content increased considerably under UV-B radiation.The changes of the etiolating type were more distinctly.It is indicated that the etiolating type is more sensitive than the normal tomato to UV-B radiation.
