Abstract

Enterolobium contortisiliquum Mor. (Vell.) Morong is a native species recommended in the recovery of degraded areas and urban areas. The objective was to evaluate the effect of chemical and mechanical scarification on the germination of the tamboril. The chemical scarification was performed in 95-98% sulfuric acid for 20 minutes and rumen fluid concentrations 1.00, 0.75, 0.50 and 0.25. Sowing was done on the sand substrate, four replications of 20 seeds in a completely randomized design. There was significant difference (p ≤ 0.05) between treatments only for germination percentage and germination speed index. Seeds scarified with sulfuric acid 98% did better, and germination speed index of 9.5 and germination percentage of 73%. Seeds of E. contortisiliquum have  seed coat impermeability to water so that the chemical scarification with sulfuric acid is a method to break seed dormancy.
