將火鶴花‘粉冠軍’、白鶴芋‘Petite’與彩虹竹蕉分別置於密閉熏氣箱(0.128 m3)，內放會釋放甲醛之木心板，以熏氣箱內含500或1200 ppm CO2濃度與不同光強度(0、60或120 μmol·m-2·s-1)處理，探討對植物吸收甲醛與光合作用的影響。結果顯示參試植物在黑暗環境中會釋放CO2，氣孔導度低但於試驗3 h期間仍可少量移除熏氣箱內木心板釋放之甲醛，但移除量比照光環境下低。參試植物於60或120 μmol·m-2·s-1光強度環境中，以1200 ppm CO2處理3 h後之葉片氣孔導度皆低於500 ppm CO2處理者，而且不利植物移除熏氣箱內的甲醛。光強度由60提高至120 μmol·m-2·s-1可降低熏氣箱內更多的CO2與甲醛濃度，使葉片淨光合作用速率與氣孔導度上升，使細胞間隙二氧化碳濃度下降。單位葉面積所移除的甲醛濃度之排序為火鶴花>白鶴芋>彩虹竹蕉。在本研究參試環境條件下，彩虹竹蕉的淨光合作用與氣孔導度皆最低而細胞間隙CO2濃度最高，移除熏氣箱內CO2與甲醛之能力最低。

Anthurium andraeanum Linden. ‘Pink Champion’, Spathiphyllum kochii Engler & Krause ‘Petite’, and Dracaena marginata Lam. ‘Tricolor Rainbow’ were placed in airtight chambers, respectively, each with a fresh wooden board that released formaldehyde. The experiment was constructed with two initial CO2 concentrations (500 or 1200 ppm) and three light intensities (0, 60 or 120 μmol·m-2·s-1 PPF) for three hours. Results showed that CO2 concentration increased and formaldehyde reduced slightly in the chamber for plants under dark conditions. Under light conditions, plants with 500 ppm CO2 had higher stomatal conductance and reduced more formaldehyde than those with 1200 ppm CO2. Increased light intensity resulted in increased net photosynthetic rate, stomatal conductance, and removal rates of formaldehyde and CO2. The efficiency of removing formaldehyde per leaf area ranked as: Anthurium > Spathiphyllum > Dracaena. Dracaena exhibited the lowest net photosynthetic rate, stomatal conductance and removal rates of formaldehyde and CO2 under the conditions constructed in this study.
