紫外线B(UV-B)辐射增强对水稻影响的研究进展

Research Advances on Rice(Oryza sativa L)to Enhanced Ultraviolet-B Radiation

紫外线是到达地面的太阳光的一部分.20世纪以来,由于多种原因,导致平流层臭氧层变薄,因而到达地表的紫外线B(UV-B)的辐射增强,对地球生物产生严重影响.本文综述了紫外线辐射增强对水稻生长发育,产量和品质影响,以及水稻的自我防护与修复机制的研究现状与动态,展望了今后紫外辐射增强对水稻影响的研究重点与研究方向.

Ultraviolet（UV） radiation is an integral part of the sunlight that reaches the surface of the earth.Since the twentieth century,the stratospheric ozone layer is becoming thinner for various reasons. So the quantity of UV-B reaching the surface of the earth is becoming higher,which has bad effects on plants.This paper summarized the research progress about the effects of UV-B radiation on the growth,development,yield and quality in rice（O sativa L）,The defence and repair mechanisms of rice were also investigated.Further research directions in this field were prospected.
