Cultivars of burley and flue-cured tobacco (Nicotiana tabacum L.) were allowed to attain steady-state exponential growth at two nitrate levels and in 400 or 1,000 ..mu..l/liter CO/sub 2/ in the ambient atmosphere. The unit leaf area rates of net CO/sub 2/ exchange were measured at the same CO/sub 2/ concentrations at which the plants were grown. The NCERs were greater at 400 than at 1,000 ..mu..l/liter CO/sub 2/ in both cultivars and at both nitrate levels. The NCERs were also greater in the flue-cured than in the burley cultivar and at the high nitrate level.
