摘要: 通过综述UV-B辐射增强对作物产生的影响,为进一步揭示作物对UV-B辐射增强的响应机制、适应变化和寻找相应的解决方法提供参考。分析发现UV-B辐射增强能对作物的形态在根、茎、叶营养器官和生殖器官方面产生负面影响,从而进一步影响作物的生物量和产量;UV-B辐射增强对植物生理的影响主要通过影响作物的叶绿体、光合作用及矿质代谢而起作用,并且这些影响具有品种间和生育期的差异。因此研究紫外辐射对作物的影响具有重要的生态学意义。

关键词: UV-B辐射, 作物形态, 作物生理

Abstract: The Influence of the enhanced UV-B radiation on crop production was reviewed to reveal the response mechanism of crops to the enhanced UV-B radiation and to provide the adaptation and resolution methods.The result showed that the enhanced UV-B radiation had an adverse effect on crop morphology of root,stem,leave systems and reproductive organs.It had a further effect on biomass and yield of crops.The effects on crop physiology of the enhanced UV-B radiation were mainly through the changes of chlorophyll,photosynthesis and mineral metabolism,which depended on the varieties and growing periods.

Key words: UV-B radiation, UV-B radiation, Crop morphology, Crop physiology
