Abstract
For selecting indicator plants of photochemical oxidants among crop species, a field survey on the foliar injuries was conducted for potato, peanut and taro cultivars. The survey indicated ‘Waseshiro’, ‘Chibahandachi’ and ‘Dodare’ for potato, peanut and taro, respectively, were the most sensitive cultivars among the ones examined. Since the sensitive cultivars are widely grown in China Prefecture, they can be used as the indicator plants of photochemical oxidants.
