摘要：

The study evaluated qualitatively and quantitatively the seed bank of an area of caatinga. 35 plots were systematically arranged 10 x 10 m, samples were randomly collected. Each sample was individually homogenized and placed to germinate in two environments: full sun and shade to 50%. Was recorded 237 individuals belonging to 13 families and 26 species were identified. The total density of the seed bank was approximately 43 seeds/m2. The treatment with shade showed a density of 33.2 seed/m2. The treatment in full sun got density of 9.28 seed/m2. The environment under shade got more seed germination and initial survival of seedlings.
