Root organic exudates of four wetland plants were studied in wetland microcosms to test their effects on the density and diversity of the rhizosphere microbes, and on the nutrient removal.An improved high-performance liquid chromatography (HPLC) was established to analyze the organic acids in the root exudates. The wetland plants had similar compositions, but different concentrations of root exudates...
The aim of the present study was to test the correlation between radial oxygen loss (ROL), photosynthesis, and nutrient removal based on the hypothesis that ROL was principally a positive physiological process of wetland plants, and was correlated with photosynthesis and nutrient removal. Thirty five emergent wetland plants were used for the measurement of ROL, photosynthesis, and nutrient removal...
