Abstract: Based on the analyses of the status the thinned stratospheric Ozone layer, and divisory of ultraviolet radiation way in this paper.Current research status on the enhanced UV-B radiation on plants was reviewed.The main research fields involved plant growth and morphological structure,plant physiological and biochemical metabolism,UV-B absorbing compounds,plant genetic material and some gene expression, plant cell membrane and antioxidant system,environment genes reciprocity with plant,population and ecosystem.It made some expectation to the future direction in this field.
