内容記述 | The influence of natural phytoplankton cell classes upon the response of urea decomposition was investigated in four reservoirs in the North Han River System. The decomposition rate of urea was 0.3 to 29.4 μ mol urea・m⁻³・hr.⁻¹ in the light and 0.2 to 14.9 μ mol urea・m⁻³・hr.⁻¹ in the dark. Much higher decomposition rates were observed at the eutrophic stations in Lake Euiam. The urea decomposition in the smaller fraction (<5 μm) exceeded that in the middle (5-25 μm) and the larger fraction (>25 μm). No differences in the ratios of urea decomposition to chlorophyll-a or photosynthesis among three fractions were observed. This might be mainly due to the difference in the standing crop of phytoplankton. These trends were no different between sampling areas and reservoirs. The greater part of urea decomposition was the phase of CO₂ liberation rate into the water. Eight to 50% of the urea decomposition was incorporated into the particulate phase in the light, but this was much lower in the dark. The results of the present study indicate that urea in reservoirs decomposes by phytoplankton rather than bacteria and the phytoplankton would be competitive to bacteria. | |||||
