espanolRESUMEN Bromelia laciniosa, conocida popularmente como “macambira”, es una planta encontrada principalmente en areas secas del Nordeste brasileno. Esta especie pertenece a la familia Bromeliaceae, cuyo fenomeno del adormecimiento en semillas ha dificultado su propagacion. En el presente estudio se evaluo la eficiencia de la escarificacion quimica en la germinacion de semillas de B. laciniosa, en dos estados de maduracion, utilizando acetona y alcohol por 30, 60 y 90 minutos de inmersion de las semillas. La inmersion de las semillas de B. laciniosa en acetona (58%) por 90 minutos se constituye en un eficiente metodo para la superacion del adormecimiento. Las semillas oriundas de frutos maduros proporcionan mayores valores de germinacion. EnglishABSTRACT Bromelia laciniosa, popularly known as ‘macambira’, is a plant found mainly in dry areas of northeast Brazil. This species belongs to the Family Bromeliaceae, whose propagation has been hindered by seed dormancy. This study aimed to evaluate the effectiveness of chemical scarification in the germination of B. laciniosa seeds at two maturation stages, by immersing them in acetone or alcohol for 30, 60 or 90 minutes. Immersing B. laciniosa seeds in acetone (58%) for 90 minutes proved to be an effective method to overcome dormancy. Seeds from mature fruits showed higher germination values.
