Relationship between ozone, meteorological conditions, gas exchange and leaf injury in Nicotiana tabacum Bel-W3 in a sub-tropical region

► Gas exchange, ozone flux and foliar injury in tobacco Bel-W3 were investigated. ► Biological processes and environmental factors varied greatly throughout the year. ► Meteorological conditions have a great importance in plant responses. ► Under unstable weather conditions, ozone flux and leaf injury had a weak correlation.
