The effect of pretreatments in Enterolobium contortisiliquum seeds (Fabaceae) from Selva Pedemontana of Argentina. Enterolobium contortisiliquum (Vell.) Morong is a tree species that lives in the Selva Pedemontana of Argentina, that is extensively exploited for ample crop. Its seeds typically exhibit low germination percentage due to the high level of dormancy. Five different methods to overcome dormancy were evaluated on seeds collected for five populations along a latitudinal and altitudinal gradient in the Selva Pedemontana. All seeds were germinated at 24 ºC and 12 h photoperiod. Total germinated seeds and mean time to germinate was recorded. Mechanical scarification and chemical scarification with sulfuric acid for 30 to 50 minutes were highly efficient in promoting germination. Enterolobium contortisiliquum (Vell.) Morong es una especie arbórea que habita en la Selva Pedemontana de Argentina, área muy afectada por cultivos extensivos, cuyas semillas típicamente presentan bajo poder germinativo debido a un elevado grado de dormición. Se aplicaron cinco métodos diferentes para ruptura de dormición a semillas recolectadas en cinco poblaciones en un gradiente de la Selva Pedemontana. La germinación se desarrolló a 24 ºC y con fotoperiodo de 12 horas. Se registró el total de semillas germinadas y la velocidad de germinación. La escarificación mecánica y la escarificación química con ácido sulfúrico por 30 y 50 minutos fueron los tratamientos altamente eficientes para promover la germinación.
