| Abstract: | Ultraviolet-B(UV-B)is an important environmental pressure factor affecting plant growth and development.More and more attention have been given to the impact of UV-B radiation intensity changes on plant ecosystems recently.In this paper,the current status of research on the effects of UV-B radiation on plant morphological development,photosynthesis,secondary metabolism and antioxidant systems,and genetic material were briefly reviewed.The mechanism and application prospects of UV-B irradiation to regulate plant morphological development,improve plant quality,improve fruit fresh-keeping ability,enhance plant resistance to biological stress,and mutation breeding were discussed. |
