Abstract The use of certain methods and techniques of periphyton research has been evaluated in connection with the study of periphyton on nymphaeid aquatic plants. Separation techniques explored are based on a combination of mechanical and chemical forces, on enzymatic action and on the chelating activity of EDTA. Mechanical separation by the application of superficial film is treated apart, because it is the only technique conserving the original pattern of periphyton. The means used to examine periphyton in situ consist of bleaching, epifluorescence and scanning electron microscopy. In the end, it is concluded that not one of the techniques is fully satisfactory. However, a combination of techniques may provide sufficient data to obtain an overall picture of species composition, microdistribution and architecture of a periphyton community.
