摘　　要：以5种多肉植物黄丽、观音莲、吉娃娃、芦荟、千佛手为研究对象,利用玻璃箱模拟甲醛逆境,比较和分析5种多肉植物净化甲醛能力的强弱及其生理指标的变化。结果表明:5种植物对甲醛均有一定的净化效果,净化能力大小依次为千佛手>黄丽>芦荟>吉娃娃>观音莲。甲醛污染会使这5种植物叶片叶绿素含量下降,其中千佛手下降最多,观音莲下降最少;MDA含量表现出不同程度的上升趋势;叶片POD酶活性升高。经综合比较,认为这5种植物中千佛手净化甲醛的效果最好。Sedum adolphii, Sempervivum tectorum, Echeveria chihuahuaunsis, Aloe vera and Sedum sediforme were used in this study to investigate the ability of removing formaldehyde and physiological mechanism in this paper by using glass box to simulate formaldehyde environmental. The results showed that all the five kinds of plants had certain absorbtive capacities on formaldehyde, and the ability declined as： Sedum sediforme〉Sedum adolphii〉Aloe vera〉Echeveria chihuahuaunsis〉Sempervivum tectoium. Formaldehyde reduced content of chlorophyll, and the decrease degree of of Sedum sediforme was the most. Formaldehyde enhanced MDA content and POD activities in five kinds of plants. In all, the Sedum sediforme was the best choose to remove formaldehyde.
