Photosynthetic rates and biomass of tobacco and melon plants under ACO2 and ECO2. (A) Light response curves of five-week-old tobacco plant; (B) Light response curves of five-week-old melon plant; (C) CO2 response curves of five-week-old tobacco plant; (D) CO2 response curves of five-week-old melon plant; (E) Fresh weight of above-ground part of tobacco plant; (F) Fresh weight of above-ground part of melon plant; (G) C:N ratio of tobacco plant; (H) C:N ratio of melon plants. Pn, photosynthetic rate; PAR, photosynthetically active radiation; Ci, intercellular CO2 concentration. Diferent letters for each species denote signifcant diferences (p ≤ 0.05).
