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.
