Summary: Aqueous extracts from green leaves of Nerium oleander L. and Dieffenbachia picta in concentrations of 0; 0,0625; 0,125 and 0,25 mg/mL were prepared with the objective of studying the allelopathic potential of these ornamental plant species on lettuce (test plant) and Bidens pilosa L seeds. The experiments were carried out in January of 2007, at the Genetic Laboratory of Santa Maria Federal University. The first count of germination (PCG), germination (G), germination speed index (IVG), root and shoot length, and fresh biomass (MF) were evaluated. Both species showed tendency to reduce the analyzed morphological variables from the concentration of 0,125 mg/mL. The seeds of Bidens pilosa L. were more sensible to aqueous extracts than lettuce seeds. The IVG showed the greatest reduction with the increase of extracts concentration. The MF of lettuce and Bidens pilosa L. plants were reduced from the concentration of 0,0625 mg/mL. Both extracts showed potential allelopathic activity.

Dieffenbachia picta nas concentrações 0; 0,0625; 0,125 e 0,25 mg/mL foram preparados com o objetivo de determinar o potencial alelopático dessas espécies utilizadas como plantas ornamentais, sobre sementes de Lactuca sativa (planta-teste) e Bidens pilosa L. O experimento foi conduzido durante o mês de janeiro de 2007, no Laboratório de Genética da Universidade Federal de Santa Maria. Foram avaliados a primeira contagem da germinação (PCG), germinação (G), o índice de velocidade de germinação (IVG), os comprimentos das raízes e da parte aérea e a biomassa fresca (MF). Ambas as espécies mostraram tendência a reduzirem os parâmetros morfológicos analisados a partir da concentração de 0,125 mg/mL, sendo que as sementes de Bidens pilosa L. foram mais sensíveis que às de alface. O IVG foi a variável que mostrou maior redução com o aumento da concentração dos extratos. A MF das plântulas de alface e Bidens pilosa L. foram reduzidas a partir da concentração de 0,0625 mg/mL. Ambos extratos mostraram atividade potencialmente alelopática.Universidade do Estado de Santa Catarina2007-09-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.udesc.br/index.php/agroveterinaria/article/view/5353Revista de Ciências Agroveterinárias; Vol. 6 No. 1 (2007); 11-21Revista de Ciências Agroveterinárias; v. 6 n. 1 (2007); 11-212238-1171reponame:Revista de Ciências Agroveterinárias (Online)instname:Universidade do Estado de Santa Catarina (UDESC)instacron:UDESCporhttps://periodicos.udesc.br/index.php/agroveterinaria/article/view/5353/3558Hoffmann, Clairomar Emílio FloresNeves, Luiz Augusto Salles dasBastos, Cristiane FreitasWallau, Gabriel da Luzinfo:eu-repo/semantics/openAccess2022-07-01T14:52:58Zoai::article/5353Revistahttps://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:2022-07-01T14:52:58Revista de Ciências Agroveterinárias (Online) - Universidade do Estado de Santa Catarina (UDESC)false
