植物根系分泌物分析及对湿地微生物群落的影响研究
Root exudates of wetland plants and the influence on the microbial community in constructed wetlands
摘要
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 different. The excreting abilities of those three plants were declined along with the growth cycle. The Spiked Loosestrlfe excretes more root exudates than both Canna and Wildrice stem. The quinone profile method was applied to study the microbial community in wetlands, and the results of this study also indicated that wetland plants also have notable impacts on components and diversity of the microbial community in constructed wetlands.关键词
