| description | Secondary metabolites are produced by certain plant species and may influence the development of some species through the action of allelopathic effects. Thus, the objective of this study was to evaluate the allelopathic effect of Lippia alba essential oil on the germination, emergence and vigor of seedlings of different batches of lettuce seeds. This experiment was conducted in a completely randomized design with a 3´5 factorial scheme consisting of three batches of seeds of the cultivar Grand Rapids® and five doses of L. alba essential oil (0, 0.25, 0.50, 0.75 and 1.00%) diluted in distilled water and homogenized in Tween® 80. Seed germination and vigor, in the laboratory (experiment I), and emergence, in a protected environment (experiment II), were evaluated. The results demonstrated that there was an inhibitory effect with a significant reduction of germination, vigor and seed emergence when L. alba essential oil was added starting at concentrations of 0.25%. The essential oil showed allelopathic potential over different lettuce seed lots, affecting germination, vigor and seed emergence. |

This experiment was conducted in a completely randomized design with a 3´5 factorial scheme consisting of three batches of seeds of the cultivar Grand Rapids® and five doses of L. alba essential oil (0, 0.25, 0.50, 0.75 and 1.00%) diluted in distilled water and homogenized in Tween® 80.

Los metabolitos secundarios son producidos por ciertas especies de plantas, y pueden influir en el desarrollo de algunas especies, debido a la acción de los efectos alelopáticos. Por lo tanto, el objetivo del trabajo fue evaluar el efecto alelopático del aceite esencial de Lippia alba en la germinación, emergencia y vigor de las plántulas de diferentes lotes de semillas de lechuga. El experimento se realizó en un diseño completamente al azar, en un esquema factorial 3´5, que consta de tres lotes de semillas del cultivar Grand Rapids® y cinco dosis de aceite esencial de L. alba (0; 0,25; 0,50; 0,75 y 1,00%) diluido en agua destilada y homogeneizado en Tween® 80. Se evaluó la germinación y el vigor de la semilla en el laboratorio (experimento I) y la emergencia en un ambiente protegido (experimento II). Los resultados obtenidos mostraron que hubo un efecto inhibitorio con una reducción significativa de la germinación, el vigor y la emergencia de la semilla cuando se añadió aceite esencial de L. alba a partir de concentraciones de 0.25%. El aceite esencial mostró potencial alelopático sobre diferentes lotes de semillas de lechuga, afectando la germinación, el vigor y la emergencia de las semillas. Metabólitos secundários são produzidos por determinadas espécies vegetais, e quando liberados no ambiente podem influenciar o desenvolvimento de outras espécies, causando efeitos alelopáticos. Dessa forma, o objetivo do trabalho foi avaliar o efeito alelopático do óleo essencial de Lippia alba (Mill.) na germinação, emergência e vigor de plântulas de diferentes lotes de sementes de alface. O experimento foi conduzido em delineamento experimental inteiramente casualizado, em esquema fatorial 3x5, constituído três lotes de sementes da cultivar Grand Rapids® e cinco doses de óleo essencial de Lippia alba (Mill.) (0%; 0,25%; 0,50%; 0,75% e 1%) diluído em água destilada e homogeneizadas em Tween® 80. Foram avaliadas a germinação e vigor de sementes em laboratório (Experimento I) e a emergência em ambiente protegido (Experimento II). Resultados obtidos demonstraram que ocorreu efeito inibitório sobre germinação, vigor e emergência das sementes quando adicionado as concentrações do óleo essencial de Lippia alba (Mill.) verificando-se o efeito alelopático deste óleo essencial sobre os diferentes lotes de sementes de alface.
