Ozone lesions in relation to senescence of attached and detached leaves of tobacco. Increased survival and growth response of hornworm larvae to elevated O 3 levels in these experiments suggests that similar responses could occur in the southeastern US tobacco production areas where O 3 levels can be high enough to injure tobacco plants.Īdepipe, N. Ozone-treated tobacco plants had higher levels of total nitrogen (primarily reduced nitrogen) and soluble carbohydrates (sugars), and lower levels of leaf-surface components, starch, nicotine, and rutin. Second instars also gained significantly more weight when they were fed for one week on plants exposed to elevated levels of O 3 than when they were fed plants grown in charcoal-filtered air. Survival of tobacco hornworm, Manduca sexta, larvae was increased when second instars were fed tobacco leaves grown in chambers with elevated levels of O 3. Ozone concentrations were established by charcoal filtration, which reduced O 3 to approximately one-half ambient, or by the addition of O 3 to unfiltered air to increase concentrations to approximately 1.4 or 1.7 times ambient O 3. Tobacco plants, Nicotiana tabacum were grown under different levels of ozone (O 3) in open-top chambers.
