title: Effects of ozone on grain quality of wheat grown in open-top chambers: three years of experimentation.
abstract: Field trials with winter wheat (Triticum aestivum L.) grown in open-top chambers and exposed to either ambient filtered (F) or unfiltered (NF) air were carried out for 3 years in northern Italy. The experiments were performed at two places, a rural and an urban site in the Po Plain. The data obtained show no significant difference in protein, starch and glucose contents between the treatments; nevertheless, a tendency towards an increase in glucose and a decrease in starch contents was observed in the F chambers compared with NF. In addition, potassium levels were lower in F than in NF treatment, while calcium were higher. Ozone levels observed in the Po Valley are not sufficiently high to cause significant differences in quality parameters of winter wheat.
