Análise do potencial alelopático do extrato das folhas secas da Bertholletia excelsa (Castanha-do-Brasil), testada na germinação da semente de Lactuca sativa L. (alface). 2022. 39f. TCC (Graduação em Ciências Biológicas) - Universidade do Estado do Amazonas, Parintins.https://ri.uea.edu.br/handle/riuea/613Allelopathy is the ability of a plant to produce substances (allelochemicals) in its secondary metabolism capable of directly or indirectly interfering with the development of another plant. he use of allelochemicals to combat invasive plants has grown in recent years, their use is a way to achieve sustainable development and reduce the use of pesticides. The Castanha-do-Brasil Bertholletia excelsa is an important tree, as it is a source of food for animals and is important for the economy, many products are derived from this tree. The experiment was conducted in the laboratory to test the allelopathic potential of its dried leaves. Lactuca sativa L. lettuce seed was used in Bioassay because it is widely used in phytotoxicity tests because it is sensitive to toxic substances. The experiment showed a great allelopathic potential of Brazil nut tree leaves.Acesso AbertoAlelopatiaAleloquímicosDesenvolvimento sustentávelTrabalho de Conclusão de Curso
