Some authors suggest the use of plant homogenates or extracts to test for allelopathy; those include the employment of fresh or dried macrophytes homogenized with water or moderate lipophilic solvents such as methanol, ethanol and acetone are also appropriate to extract more lipophilic compounds. Bioassays of aqueous plant extracts suggested that phytotoxins are directly released by the plant residues. A number of characteristics is important when choosing a bioassay including species, growth form and phenology; particularly, germination and seedling development are the more appropriate life stage to apply for studies about elemental allelopathy. The present study evaluated the bioactivity of aqueous and acetone extracts from Ceratophyllum demersum L. on Lactuca sativa L. seedlings
