Resumo: Allelopathy is an ecological mechanism that influences the development of neighboring plants. The objective was to evaluate the allelopathic potential of Cenostigma bracteosum and Sarcomphalus joazeiro on seed germination and initial growth of Mimosa caesalpiniifolia seedlings. Seeds of this species were placed to germinate on paper towel substrate, and then moistened with extracts from dry leaf of S. joazeiro and C. bracteosum at 1.0; 2.5; 5.0 and 10.0% (w.v-1), and control (0.0% - distilled water) at 25 °C. The variables evaluated: germination, germination speed index, primary root length and root system dry weight of the seedlings. Positive allelopathic effects of S. joazeiro leaf extracts were observed on the vigor of M. caesalpiniifolia; when used in low concentrations (up to 2.6%), C. bracteosum leaf extracts stimulated germination of M. caesalpiniifolia seeds and showed more severe toxic effects when exposed to high concentrations (5.0%). S. joazeiro leaf extracts favor the germination and vigor of M. caesalpiniifolia seedlings, while C. bracteosum leaf extracts cause phytotoxic effects on seed germination and initial growth of M. caesalpiniifolia seedlings from the concentration of 5%. Therefore, there are indications of benefits for regeneration or associated forest composition between M. caesalpiniifolia and S. joazeiro.

El objetivo fue evaluar el potencial alelopático de Cenostigma bracteosum y Sarcomphalus joazeiro sobre la germinación de semillas y el crecimiento inicial de plántulas de Mimosa caesalpiniifolia. Semillas de esta especie se colocaron para germinar sobre sustrato de papel toalla, y luego se humedecieron con extractos de hoja seca de S. joazeiro y C. bracteosum a 1,0; 2,5; 5,0 y 10,0% (p.v-1) y control (0,0% - agua destilada) a 25 °C. Las variables evaluadas: germinación, índice de velocidad de germinación, longitud de raíz primaria y peso seco del sistema radical de las plántulas. Se observaron efectos alelopáticos positivos de extractos de hojas de S. joazeiro sobre el vigor de M. caesalpiniifolia; cuando se usaron en concentraciones bajas (hasta 2.6%), los extractos de hojas de C. bracteosum estimularon la germinación de semillas de M. caesalpiniifolia y mostraron efectos tóxicos más severos cuando se expusieron a concentraciones altas (5,0%). Los extractos de hojas de S. joazeiro favorecen la germinación y vigor de las plántulas de M. caesalpiniifolia, mientras que los extractos de hojas de C. bracteosum provocan efectos fitotóxicos sobre la germinación de semillas y el crecimiento inicial de plántulas de M. caesalpiniifolia a partir de la concentración del 5%. Existen indicios de beneficios para la regeneración o composición forestal asociada entre M. caesalpiniifolia y S. joazeiro.A alelopatia é um mecanismo ecológico que influencia o desenvolvimento das plantas vizinhas.
