Effect of carbon dioxide-enrichment on tobacco
Three-wk old seedlings of tobacco variety Bell-W3 and Bell-B were grown in growth chambers under sunlight and subjected to 3 levels of ambient CO2 concentrations: 300-315 (low), 350-400 (medium) and 600-700 (high) umol mol-1.Weekly measurements of rates of photosynthesis, respiration, transpiration...
