Supriya Tiwari and Madhoolika Agrawal Abstract The photochemical reactions leading to O₃ formation and the variables on which these reactions depend are undergoing rapid alterations owing to the present climate change scenario. The multifarious set-up related to O₃ formation in the troposphere makes it difficult to check the continuously increasing concentration of O₃ around the globe. O₃ concentration has already crossed the standard limit for vegetation set by European Union (EU) in most of the parts of the World, which is evident by a number of O₃ induced crop yield reduction studies. Therefore the demand of the time is to develop certain strategies that will help in alleviating the deleterious effects of O₃ on plant performance. This target can be achieved by adopting different approaches such as improved agronomic practices; selection of O₃ resistant cultivars, improving photosynthetic efficiencies of O₃ exposed plants etc. Several strategies have been followed to achieve these targets, important ones being CO₂ fertilization and soil nutrient amendments. In addition to this, air quality management practices using CH₄ emission control is also considered to be an important strategy in minimizing O₃ induced stress in plants. It has been shown that CO₂ fertilization increased the carbon input which can be incorporated in plant biomass and subsequently helps in maintaining yield of plants exposed to O₃ stress. Treatment of additional nutrient helps in the repair of the O₃ injured plants thus sustaining their yield. As apparent through a number of studies, these strategies have proved quite efficient in partially mitigating O₃ stress in plants. However, more experimentation is required before confirming the use of these approaches in mitigating O₃ injury and implementing them in daily agricultural practices.
