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.
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.
