摘要:
选择巢蕨(Neottopteris nidus)、巴西铁(Dralaena fragrans)、虎尾兰(Sansevieria trifasciata)和黑美人(Aglaonema commutatum)4种室内盆栽植物作为典型的试验材料,以15 mg·m-33甲醛分别进行熏蒸处理,测定单位干物质甲醛的吸收量相对电导率丙二醛含量和叶绿素含量等,以研究这些植物在甲醛胁迫下的生理动态反应结果表明:在甲醛胁迫的4 d时间内,巢蕨和巴西铁的单位干物质甲醛吸收量均在第3天达到峰值,而黑美人和虎尾兰则一直在缓慢增加,其中以巢蕨吸收的量最多,巴西铁单位干物质甲醛吸收量最少; 4种植物的相对电导率丙二醛的含量均随甲醛胁迫时间的增加而增加,以巢蕨的相对电导率最高,虎尾兰最低,但巴西铁的丙二醛的含量最高,巢蕨最低; 4种植物的叶绿素含量均随甲醛胁迫时间的增加而降低,其中黑美人降低幅度最高,虎尾兰最低
Abstract:
The physiological dynamic changes for the four species indoor potted plants,Neottopteris nidus,Dralaena fragrans, Sansevieria trifasciata and Aglaonema commutatum,were studied respectively with these indexes such as the unit dry matter of Formaldehyde(FDH)absorption,the relative electric conductivity(REC),the malondialdehyde(MDA)content,and the leaf chlorophyll content,under the stress of FDH with the treatment concentration of 15 mg·m-3. The results indicated that in four days of FDH intimidation,the unit dry matter of FDH absorption for both Neottopteris nidus and Dralaena fragrans reached to the peak at the third day,while Sansevieria trifasciata and Aglaonema commutatum increased slowly. Meanwhile,the most and least content of the unit dry matter for FDH absorption were Neottopteris nidus and Dralaena fragrans respectively. The REC and MDA contents for the four species increased with the raise of FDH stress time,the highest and lowest REC were Neottopteris nidus and Sansevieria trifasciata respectively,the highest and lowest MDA were Dralaena fragrans and Neottopteris nidus respectively. The leaf chlorophyll content for the four species decreased with the increasing of FDH stress time,the highest and lowest decreasing amplitude were Aglaonema commutatum and Sansevieria trifasciata respectively.
