| 摘 要： | 植物是人工湿地的重要组成部分,其通过根系分泌物对湿地中的微生物群落结构产生影响。本研究分析了美人蕉（Canna indica）、茭白（Zizania caduciflora）、千屈菜（Lythrum salicaria Linn）等3种湿地植物的根系分泌能力及分泌物组成。3种植物的根系分泌物主要组成物质相似,均含有小分子有机酸、酚类、芳香族蛋白质,但各组成比例有所差异。分泌能力则随生长周期持续下降,千屈菜的分泌能力远强于美人蕉和茭白。本研究利用醌指纹研究人工湿地中微生物群落结构,结果发现不同湿地植物对湿地中微生物的组成和多样性产生显著影响。

| Abstract: | Plants are the important component of constructed wetlands,and their root exudates will impact the microbial community in constructed wetlands.In present study,the excreting ability and root exudates of Canna(Canna indica),Wildrice stem(Zizania caduciflora) and Spiked Loosestrlfe(Lythrum salicaria Linn) were studied.Those three plants have similar root exudates,which were mainly composed by organic acids,phenol and aryl protein.However,the composition proportions in root exudates of those three plants were ... |
