Abstract: Seventeen German and five Greek cultivars from the harvest 1987 and 25 German Geudertheimer cultivars, - new breeding lines and common types from Oriental-, Cigar-, Burley- and Virgintobacco -, from the harvest 1990 were analyzed according to nitrogen fertilization for the leaf constituents nitrate, alkaloids, sugar, and nitrogen, for the smoke constituents condensate, nicotine, carbon monoxide and nitric oxide: The limitation to 15 mg condensate per cigarette, asked by the European Commission for 1993, could only be fulfilled with the lower stalk positions of the cultivars. Nicotine was changing according to the tobacco types. Carbon monoxide was found in a middle range equal for all types. Nitric oxide was changing according to the nitrogen fertilization and the cultivars. A corresponding increase of the nitric oxide percentage in the tobacco smoke was observed in varieties needing more nitrate fertilizer. Nitrate, nicotine and the sum of nornicotine and myosmine in the leaf correlated with cultivar, climate and fertilization. The nitrosamines in the tobacco leaf and the tobacco smoke varied with the nitrate content in the cultivars, the harvesting and curing conditions. Cigarettes, made of tobacco leaves and containing small amounts of nitrate, generated less nitric oxide than cigarettes made of tips, which contained more nitrate. Twenty-five breeding lines of dark air cured tobacco from the harvest 1990 were identified with Polyacrylamide Gel Electrophoresis.
