摘要：

Three independent methods were used to quantify the efficiency of a mechanical agitation technique for the removal of epiphytes from four submersed macrophyte species. Time course samples were collected for epiphytic chlorophyll, dry weight, and algal and diatom cell counts following cumulative agitation periods of 10, 30, 60, 90, and 120 s. Statistically identical removal efficiencies were found for all macrophyte host species. Mean removal time for over 88% removal efficiency was 40 +/- 6 s. (C) 1997 Elsevier Science B.V.
