摘要
研究了4种室内常见观赏植物对甲醛的吸收能力,并对植物吸收甲醛的生理机理进行了初步探讨。结果表明,4种观赏植物对甲醛污染的净化能力大小表现为绿萝>金边虎尾兰>玉树>大花惠兰。甲醛污染造成植物叶片叶绿素含量下降而MDA含量上升。不同植物类型叶绿素含量下降幅度和MDA含量上升幅度不同。室内存在甲醛污染时,适宜选择净化效果较好而伤害程度较轻的植物。
Four kinds of interior plants are used in this research to investigate the ability of removing formaldehyde and physiological mechanism. The results show that the abilities of four interior plants to absorb formaldehyde decline as follows： Epipremnum aureum 〉 Sansevieria trifasciata Prain. var. laurentii N. E. Brown 〉 Crassula argentea 〉 Cymbidium hybridium. Formaldehyde reduces chlorophyll content, but enhances MDA content in interior plants. The responses of chlorophyll and MDA contents to formaldehyde differ among four kinds of interior plants. Those interior plants that can absorb formaldehyde but be hurt lightly are befittingly to be selected to improve indoor environment.
