| Research Abstract |
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.
