Abstract

O3 phytotoxicity to tobacco was demonstrated in several rural locations in Catalonia during a pilot study from March to September 1994. At coastal locations, O3 injury was found even on O3 resistant cultivar Bel-B such injury did not occur in the interior of Catalonia. In the coast, there are higher concentrations of ozone and higher humidities that rise stomatal conductance, and therefore the ozone effect. Injured leaf reflectance spectra showed higher values in the red and lower values in the near infrared areas, opening interesting possibilities for remote sensing of ozone effects.
