目的 检测稀土生物调节剂LaCl3对甲醛胁迫下4种室内观赏植物降醛能力的影响，筛选出LaCl3提升降醛能力最明显的观赏植物。方法 采用熏蒸法考察检测稀土生物调节剂LaCl3对甲醛胁迫下室内观赏植物抗性的影响，并研究其甲醛抗性的生理生化机制。结果 分别喷施适宜剂量LaCl3后，4种室内观赏植物单位叶面各吸收甲醛 能力均有所增强，提升效率分别为：常春藤15.16%、吊兰4.72%、绿萝19.75%、虎尾兰7.68%；甲醛胁迫下，绿萝叶绿素含量降低了39.87%，质膜透性和MDA累积量分别增加了8.17%、56.92%，POD活性升高了11.32%；经LaCl3预处理后， 较甲醛胁迫组，绿萝叶绿素含量降幅与质膜透性、MDA浓度增幅均变小，而POD活性增幅变大。结论 喷施LaCl3对绿萝降醛能力的提高效率最大。

[Objective] This study aimed to determine the effect of rare earth biological regulator LaCl3 on the absorptive capacity to formaldehyde of four indoor ornamental plants, and to screen out the plant whose absorptive capacity to formaldehyde can be increased most greatly by LaCl3. [Method] Effect of LaCl3 on absorptive capacity to formaldehyde of four indoor ornamental plants was studied through fumigating in laboratory. Simultaneously, the indoor ornamental plant, which could significantly en- hance the degradation capacity of formaldehyde, was screened out to study the physiological and biochemical mechanisms of formaldehyde resistance. [Result] The ability to absorb formaldehyde of four indoor ornamental plants was enhanced by dif- ferent ranges after spraying with LaCl3 at suitable concentrations. The ability to ab- sorb formaldehyde of Hedera nepalensis var. sinensis, Chlorophytum comosum, Scindapsus aureun and Sansevieria trifasciata increased by 15.16%, 4.72%, 19.75% and 7.68%, respectively. In the four indoor ornamental plants, the capacity of S. au- reun to absorb formaldehyde was greatly improved by spraying LaCl3. When S. au- reun was stressed by formaldehyde, its chlorophyll content decreased by 39.87%, membrane permeability, MDA accumulation and POD activity increased by 8.17%, 56.92%, and 11.32%, respectively. However, compared the pre-spraying group with the no-spraying group under formaldehyde stress, chlorophyll content of S. aureun reduced less, membrane permeability and MDA cumulative both increased less, but POD activity increased more. [Conclusion] The formaldehyde absorption capacity of S. aureun was mostly improved after LaCl3 was sprayed.
