摘要
阐述了UV-B辐射与生态系统的相互关系, 即胁迫与调控. UV-B 辐射不仅是植物的一种环境胁迫因子, 还是植物和生态系统进化中的一个重要调控因子. 植物次生代谢和形态变化是UV-B辐射调控生态系统的重要途径. 自然生态系统可能产生抗性物种来适应增强的UV-B辐射. 人工培育抗性作物品种则是减轻UV-B 辐射对农田生态系统影响的可行的调控手段.
This paper elaborates that the interaction between UV B and ecosystem, i e. stress and regulation. UV B radiation is not only an environmental stress factor for plants, but also an important regulation factor for the evolution of plants and ecosystem. Changes in secondary metabolites and morphological characteristics of plants are important way that UV B radiation regulates ecosystem. Resistant species could originate to adult increasing UV B radiation in natural ecosystem. It is possible for breeding resistant cultivar to minimize deleterious effects of UV B radiation on agro ecosystem.
