【Abstract】 Iron (FeCl3) enrichment experiment was carried out at 6.3°N, 110°E in the South China Sea. Cell abundances of the main groups of picoplankton Synechococcus , Prochlorococcus, picoeu-karyote and heterotrophic bacteria were traced during the experiment by flow cytometry ( FCM) . Results showed that picoplankton responded rapidly to iron of nano mole concentration. However, high concentrations of iron benefited pico-autotrophs in long term incubation course. Within the picoplankton community , Synechococcus required higher concentration of Fe than other picoplankton. When chlorophyll a bio-mass was considered, quota of nanoplankton (2-20 μm) increased with increasing Fe concentration. High concentrations of iron shifted the community from pico-phytoplankton dominance to nano-phytoplank-ton dominance at the end of the experiment.
