几种室内观赏植物对甲醛的吸收能力

The Indoor Ornamental Plants Decontamination Ability for Formaldehyde

选用15种常用室内观赏植物为试材,采用室内模拟试验,以熏气12 h后植物单位叶面积吸收甲醛的量、叶绿素含量、植物细胞膜透性和丙二醛含量为指标,评价不同植物对甲醛气体的净化能力。结果表明,15种植物均可以有效吸收甲醛,单位面积吸收量前3位的为虎皮兰、绿萝、樱花吊兰;各种观赏植物对甲醛的耐受性均存在差异。

15 indoor ornamental plants were evaluated in a simulated indoor environment,after 12-hours-long smoke,per leaf area formaldehyde adoption amount,the formaldehyde Chlorophyll content,the plasma membrane permeability and the MDA content were measured to assess those plants' physiological responses to formaldehyde stress.The results showed that the capacities of 15 plants of removing formaldehyde were different,and the first 3 plants according to the unit area removal capacities measured were Sansevieria trifasciata,Scindapsus aureum,and Atenia cordifolia.The resistances of different species to formaldehyde stress were different.
