Abstract The allelopathic potential of a cattail species (Typha domingensis) towards the common water fern (Salvinia minima) was studied in a short-term bioassay. Aqueous extracts of cattail plants (roots, stems, and leaves) as well as two of its phenolic compounds (2-chlorophenol and salicylaldehyde) were found to inhibit the growth of Salvinia when incorporated in the growth medium. After a period of seven days, chlorophyll concentration, fresh weight, dry weight, and number of fronds of Salvinia were compared and correlations were found among the different parameters. The results suggest an inhibitory effect by components of Typha, especially of the root fractions. Results from pure chemicals are in qualitative and quantitative agreement with those obtained from the cattail extracts.
