- Abstract
Allelopathy is a strategy of plants to defend and delimit their territory, greatly common in weeds. The snakeweed (Stachytarpheta cayennensis) is a type of weed widely found in cultivation areas and in urban areas in the Brazilian Amazon. Only few researches on allelopathy deal with anatomic changes that secondary metabolites cause on the affected plants. Current paper analyzes the allelopathic activity of five concentrations of the alcoholic extract (0; 0,5; 1; 2; 4%) of S. cayennensis at the level of anatomic changes in Cucumis sativus seedlings. Results evidence an increase in thickness of anatomic structures of the organs in aqueous and alcoholic extracts, revealing pronounced thickness as concentrations of the extract increase. The release of compounds that interfere in the development of C. sativus is an important datum to be employed in the development of alternative strategies instead of herbicides in other cultivations by an ecological management of weed.
