UV-B辐射增强影响作物生长发育的研究进展

摘要

The effect of enhanced UV-B radiation on crop growth and development is currently a hot topic in scientific research.In this paper,we reviewed the research status and trends of the effect of UV-B radiation enhancement on crop growth and development,discussed the influences on crop morphological struc-ture,photosynthetic and physiological metabolism,antioxidative system,cell membrane and DNA damage, and the underlying molecular mechanism was explored.The issues worth further discussing in the study of en-hanced UV-B radiation on crops were also prospected in this review.%UV-B 辐射增强对作物生长发育的影响是目前科学研究的热点之一,本文综述了国内外有关UV-B辐射增强对作物生长发育影响的研究现状与动态,讨论了UV-B辐射增强对作物形态结构、光合生理代谢、抗氧化系统、细胞膜和DNA损伤等方面的影响,同时还探讨了UV-B辐射影响作物生长发育的分子机制,并展望了UV-B 辐射增强影响作物生长发育研究领域中值得深入探讨的问题.
