Resumo

The objective of this study was to determine the allelopathic potential of Erythroxylum rosuliferum O.E. Schulz; Erythroxylum stipulosum; Erythroxylum cuneifolium (Mart) O.E. Schulz; Erythroxylum vacciniifolium Mart. and Erythroxylum barbatum O.E. Schulz. Bioassays were performed to examine the seed germination and initial growth of seedlings of Lycopersicum esculentum Mill (tomato) and Allium cepa L. (onion) in Petri dishes following exposure to an ethanolic extract of fresh leaves from the test species at various concentrations. The growth of the tomato and onion seedlings was inhibited with the extracts of the species tested, and significant alterations in the development of the shoots and primary roots were observed. These results suggest that the five species that were evaluated have allelopathic properties.
