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

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.
