常用室内观赏植物吸收甲醛能力的研究

Research on Formaldehyde of Absorption Abilities Common Indoor Ornamental Plants

以16种室内常用观赏植物为试材,采用叶表皮离析法、石蜡切片法,观察和分析了气孔密度、气孔长度、气孔开度、叶片组织结构疏松度和紧密度等指标,研究植物吸收甲醛的能力及其与叶片组织结构的关系。结果表明:非洲茉莉、九里香、橡皮树、红钻、绿萝吸收甲醛的能力较强,竹节海棠、玉树、榕树、金钱树、紫鸭趾草吸收甲醛的能力较弱,虎皮兰、绿宝石、虎刺梅、落地生根、麒麟掌、红掌吸收甲醛的能力居中;植物吸收甲醛能力与气孔长度、气孔开度、叶片组织结构的疏松度和紧密度无明显关联。

Taking 16 common indoor ornamental plants as malerials,using the methods of leaf epidermis of separation and paraffin section, the density, length, aperture of stoma, the porosity and the compactness of leaf tissue structure observation index were compared and analyzed, in order to study the absorption abilities of plants, and the relation between these abilities and the plants anatomical characteristics. The results showed that the ability of absorbing formaldehyde of Fagraea ceilanica ,Murra ya paniculata , Ficus elastica ,Philodendron mandaianum , Scinda psus aureus were stronger;the ability of absorbing formaldehyde of Begonia maculate Raddi,Crassula argentea ,Ficus microcarpa, Zamioculcas zamiifolia, Setcreasea purpurea were weaker; the ability of absorbing formaldehyde of Sansevieria tri f asciam , Philodendron erubescens, Euphorbia milii , Kalanchoe pinata, Euphorbia nerii folia ,Anthurium andraeanum in the middle. And there was no obvious relation between the absorption abilities and the selected observation index.
