Effects of ozone on Japanese agricultural crops

Abstract

Field surveys and experimental studies of the effects of ozone on Japanese agricultural crops have been conducted since the early 1970s. We review these research studies comprehensively, in chronological order. In the 1970s, most studies of the effects of ozone on agricultural crops, and the evaluation of ozone-induced foliar injuries, were field surveys. Since the 1980s, there has also been considerable research using various facilities, such as open-top chambers and controlled-environment growth cabinets; these studies are concerned with the response to and mechanism of ozone influence on various crops. In addition, since the last half of the 1990s, informative studies have been carried out to assess and map critical levels of ozone in relation to Japanese agricultural crops.
