摘　　要：以3种常见的室内观叶植物:吊兰、龙舌兰和广东万年青为对象,通过对植物进行熏蒸实验,研究了3种室内观叶植物净化甲醛污染的能力大小及其生理机理。结果表明3种植物对甲醛均具有一定的净化效果,其净化能力大小表现为吊兰>龙舌兰>广东万年青。甲醛污染造成3种植物叶片叶绿素含量下降,其中吊兰下降最多,达40.71%。其次为广东万年青和龙舌兰;叶片SOD活性升高,MDA含量上升,不同花卉类型表现不同的变化趋势。综合比较,认为3种植物中吊兰是清除甲醛污染较理想的选择。Chlorophytum comosum, Agave americana Linn. and Aglaonema modestum were used in this study to investigate the ability of removing formaldehyde and physiologieal mechanism was discussed in this paper. The results showed that three kinds of indoor foliage plants all had certain absorptive capacities on formaldehyde, the ability of absorbing formaldehyde declined as： Chlorophytum comosum 〉 Agave americana Linn〉 AgIaonema modestum. Formaldehyde reduced content of chlorophyll, the chlorophyll drop of Chlorophytum comosum was the most. Formaldehyde enhanced SOD activities and MDA content in three kinds of plants. But the trends in changes are different with different plants. In conclusion, Chlorophytum comosum was the optimum choice for formaldehyde purification among three kinds of plants.
