The objective of this work was to verify the effect of different removal methods of the sarcotesta of Jaracatia spinosa (Aubl.) A. DC. seeds on the germination percentage, (SGI) Speed of Germination Index and length of the aerial part. The seeds were submitted to the following treatments: 1 - without sarcotesta removal; 2 - removal with friction on sieve, with sand; 3 - removal with friction on sieve with whitewash; 4 - removal with blender, 5 - removal with seeds pulpremoval and 6 - removal with chemical solution (immersion, for 30 minutes, in solution for 1.0 L of water, 3.5 mL of sodium hypochlorite, 3.0 mL of muriatic acid and 22.5g of caustic soda). The presence of the sarcotesta harms the seed germination and development. The best methods for the removal of the jaracatiá seeds sarcotesta are the friction on sieve with sand or whitewash.
