It is projected that the increasing concentration of surface ozone will have large negative impacts on crop production. This study was conducted to elucidate protection mechanisms in crop species against ozone stress, and, thereby, to contribute to improved prediction of and mitigation options against the ozone impacts. The findings include difference in the ozone impacts between crop varieties and growth stages, the relationship between the ozone impacts and anti-oxidative substances in plant tissues. It was also found that the damage to the plant tissues could be due mostly to extra energy and oxidants resulted from the plant responses to ozone than the increased ozone per se.

预计地表臭氧浓度的增加将对农作物生产产生较大的负面影响。这项研究的目的是阐明作物物种对抗臭氧胁迫的保护机制，从而有助于改进对臭氧影响的预测和缓解方案。研究结果包括作物品种和生长阶段之间臭氧影响的差异、臭氧影响与植物组织中抗氧化物质之间的关系。研究还发现，对植物组织的损害可能主要是由于植物对臭氧的反应产生的额外能量和氧化剂，而不是臭氧本身的增加。
