摘要
紫外线-B(UV-B)是影响植物生长发育的重要环境压力因子。UV-B辐射强度变化对植物生态系统造成的影响,已成为国内外研究热点。本文从UV-B辐射对植物形态发育、光合作用、次生代谢和抗氧化系统以及遗传物质的影响等方面,对国内外研究现状进行了简要述评。对UV-B辐照调节植物形态发育、改善植物品质、提高果实保鲜能力、增强植物抵抗生物胁迫能力和诱变育种的机制及其应用前景进行了深入探讨与展望。
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.
