| 摘 要： | 为了揭示臭氧（O3）浓度升高对植物活性氧代谢系统的影响机理，从代谢生理角度，总结了近年来国内外关于臭氧浓度升高对植物活性氧自由基代谢速率、细胞膜脂过氧化程度、抗氧化系统及生物量和产量影响的研究进展，同时，就臭氧浓度升高与二氧化碳浓度升高的复合作用对植物活性氧代谢系统的影响，及阐明二者相互作用对植物抗氧化系统影响机理的研究进行了综述。在此基础上指出在未来研究中，要在分子水平上进一步深入研究植物活性氧代谢系统对高浓度臭氧、二氧化碳复合作用的响应机理，并应加强高浓度二氧化碳对臭氧胁迫下植物抗氧化系统影响的研究，为解决如何减轻臭氧浓度升高对植物造成的氧化伤害提供基础理论依据。

| Abstract: | In order to reveal effects mechanism of elevated ozone concentration on plants reactive oxygen species metabolic system, new research advances on the effects of elevated ozone exposure on plants reactive oxygen species radicals metabolic rate, extent of cell lipid peroxidation, anti-oxidative systems, biomass and yield in the paper were summarized from the view of metabolism physiology. Meanwhile, the studies on the effects of elevated ozone and carbon dioxide concentration combined on reactive oxygen species metabolic system of plants and the research which can explain the effects mechanism of elevated ozone and carbon dioxide concentration in combination on plants anti-oxidative systems were reviewed. It put forward that research at molecule level should be emphasized in the future on the response mechanism of plants reactive oxygen species metabolic system to elevated ozone and carbon dioxide exposure combined. In addition, studies on the effects of plants anti-oxidative systems under elevated carbon dioxide concentration to ozone stress should be strengthened, which can provide foundational theory and gist for finding out the way to mitigate plants oxidative damage resulted from elevated ozone concentration. |
