摘要: 臭氧是重要的温室气体之一,大气中臭氧浓度不断增加。高浓度臭氧对植物有高度毒性,能够给植物带来可见的叶片伤害,体内活性氧水平上升,同时也能刺激植物体内抗氧化系统的活性。目前高浓度臭氧对植物抗氧化系统的影响已经成为植物对全球变化响应研究的重要方向之一。本文综述了国内外关于高浓度臭氧对植物的毒害机理、植物对于高浓度臭氧伤害的抵御反应、以及在高浓度臭氧与CO2复合作用对植物影响的相关报道,以期改善人们对臭氧浓度升高对植物影响的理解。

Abstract: As a major greenhouse gas, ozone concentration is increasing in troposphere. The elevated ozone is highly toxic to plants, which can cause visible foliar injury and increase the level of active oxygen in plant, but also, can stimulate the activity of plant anti-oxidative system. To study the effects of elevated ozone on the anti-oxidative oxygen system in plants is an important topic in researching the responses of plants to global change. In this paper, the research advances in toxic mechanism of elevated ozone to plants, resistance responses of plants to elevated ozone, and effects of CO2 and ozone on plant anti-oxidative system were summarized, which could be helpful to improve the understanding about the effects of elevated ozone on plants.
