摘要
甲醛会严重威胁人类生命安全并造成环境污染,植物对室内化学污染抗性的强弱是持续吸收和净化污染物的前提和基础,丙二醛是反映细胞膜质过氧化水平和受损程度、衡量植物耐胁迫能力的重要指标。文章采用密闭熏气法,研究了3种不同质量浓度甲醛胁迫对7种室内耐阴观叶植物体内丙二醛的质量摩尔浓度变化的影响,分析了供试植物对甲醛污染的抗性能力。结果表明:在3.0、6.0、9.0 mg/m^(3)质量浓度的甲醛胁迫下,供试植物丙二醛的质量摩尔浓度均随甲醛质量浓度的升高呈上升趋势,其中不夜城芦荟体现抗性最强,丙二醛的质量摩尔浓度变化率最小,其值分别为20.97%、35.28%、80.31%;7种供试植物抗性由大到小排序为不夜城芦荟>竹柏>金钻蔓绿绒>黑叶观音莲>粉网纹草>红网纹草>白网纹草。
Formaldehyde poses a significant threat to human safety.The ability of plants to resist indoor chemical pollution is essential for their continuous absorption and purification of pollutants.Besides,the contents of malondialdehyde,which reflects the peroxidation level and the damage of cell membranes,serves as an important indicator to assess plant stress tolerance.This paper investigates the influences of three kinds of stress with different formaldehyde concentrations on the molality of the malondialdehyde contents of seven indoor shade tolerant foliage plants,and analyzes the resistance of the tested plants to formaldehyde pollution.The results show that under the stress of formaldehyde concentrations at 3.0 mg/m^(3),6.0 mg/m^(3) and 9.0 mg/m^(3),the molality of the malondialdehyde contents all demonstrates an increasing trend with the increase of the concentrations.Among them,Aloe nobilis exhibits the strongest resistance and the rate of change of the molality of the malondialdehyde contents is the smallest,with values of 20.97%,35.28%and 80.31%,respectively;the order of resistance of these seven indoor shade tolerant foliage plants is as follows:Aloe nobilis>Podocarpus nagi>Philodendron congo>Alocasia amazonica>Fittonia verschaffeltii‘Flaming Fire’>Fittonia verschaffeltii>Fittonia verschaffeltti var.minima.
