Summary: Aqueous extracts from dry leaves of Plectranthus barbatus Andrews (EBIN), in concentrations of 0; 25, 50, 75, and 100% (v/v), were prepared with the objective of studying the allelopathic potential of this medicinal species on Lactuca sativa L. and Bidens pilosa L. seeds. The experiment was carried out in January of 2009, at the Genetic Laboratory of Santa Maria Federal University. The first count germination (PCG), germination (G), germination speed index (IVG) and shoot and root length were evaluated. All parameters were affected by EBIN of P. barbatus from the lower concentration on. The seeds and seedlings of B. pilosa presented greater sensitivity to the extracts than those of L. sativa. The results allow us to infer that EBIN of P. barbatus have allelopathic potential.

O experimento foi conduzido no mês de janeiro de 2009, no Laboratório de Genética Vegetal da Universidade Federal de Santa Maria. Foram avaliados a primeira contagem da germinação (PCG), a germinação (G), o índice de velocidade de germinação (IVG) e o comprimento da parte aérea e das raízes. Todos os parâmetros avaliados foram afetados pelos EBIN de P. barbatus a partir da menor concentração, sendo que as sementes e as plântulas de B. pilosa demonstraram maior sensibilidade aos extratos do que as de L. sativa. Com os resultados obtidos pode-se inferir que EBIN de Plectranthus barbatus possui potencial alelopático.Universidade do Estado de Santa Catarina2010-03-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.udesc.br/index.php/agroveterinaria/article/view/5287Revista de Ciências Agroveterinárias; Vol. 9 No. 1 (2010); 66-73Revista de Ciências Agroveterinárias; v. 9 n. 1 (2010); 66-732238-1171reponame:Revista de Ciências Agroveterinárias (Online)instname:Universidade do Estado de Santa Catarina (UDESC)instacron:UDESCporhttps://periodicos.udesc.br/index.php/agroveterinaria/article/view/5287/3497Azambuja, NatashaHoffmann, Clairomar Emilio FloresNeves, Luiz Augusto Salles dasinfo:eu-repo/semantics/openAccess2022-07-01T14:55:48Zoai::article/5287Revistahttps://periodicos.udesc.br/index.php/agroveterinaria/PUBhttps://periodicos.udesc.br/index.php/agroveterinaria/oairca.cav@udesc.br | portal.periodicos@udesc.brhttps://doi.org/10.5965/223811712238-11711676-9732opendoar:2022-07-01T14:55:48Revista de Ciências Agroveterinárias (Online) - Universidade do Estado de Santa Catarina (UDESC)false
