Abstract

A two-year open field experiment was carried out to study the effect of elevated carbon dioxide (CO2) and nitrogensupply on fruit components of tomato. Korall determinate growth type processing tomato cultivar plants were planted and cultivated for the entire growing season in open top chambers (OTC) in years 2007 and 2008. Compared with the control (350 ppm) CO2 enrichment (700 ppm) significantly decreased the lycopene content at all three harvest dates in both years, but higher supply of nitrogen and 700 ppm CO 2 resulted in significantly higher lycopene values in second year. Elevated nitrogen concentration combined with 700 ppm CO2 significantly increased the °Brix, sugar content, total phenolics, and total antioxidant status (TAS) of tomato fruits.
