The guariroba is a palm tree that splies a bitter palmetto. This species has low germination and demands a long time for it. This study aimed to determine a treatment to increase germination and to reduce the time expended by guariroba seeds for it. The treatments were: 1- fresh cocoas with pulp; 2 - fresh cocoas without pulp; 3 - dry and fired cocoas; and 4 - dry cocoas. The observations were made at 20, 30, 40, and 50 days. The treatment 3 didn’t present germination. The statistic tests results showed highly significant differences among other treatments (1, 2 and 4) in germination of seeds. The orthogonal displaying of treatments effects showed better germination of fresh and dispulped cocoas (1% probability). Treatment 2 showed germination increase after 20 days (y = 0.05714 + 2.5 X - 0.0257x², with R2 = 0,99**). KEY-WORDS: Syagrus; germination; bitter palmetto.
