| 摘 要： | 大气平流层的臭氧层逐渐破坏导致太阳辐射中抵达地球表面的UV-B辐射增加，对作物产生不同程度的影响.本文讨论了UV-B辐射增强对作物生理代谢、DNA损伤和蛋白质含量的影响.UV-B辐射增强，作物叶片类黄酮含量增加、叶绿素含量降低、光合作用减弱，同时UV-B辐射诱致基因活性变化,导致DNA损伤和蛋白质含量的改变.

| Abstract: | Ozone depletion in stratosphere has led to the increase of solar UV-B radiation reaching to the earth surface,which would affect crops to various extents.This review dealt with the effects of enhanced UV-B radiation on the physiological metabolism,DNA damage and protein content of crops.Enhanced UV-B radiation could increase crops' flavonoid content but decrease their chlorophyll content and photosynthesis,induce gene change,and result in DNA damage and change of protein content. |
