Abstract: Cerrado is a typical Brazilian vegetal formation, considered neotropical savanna, that covers about 25% of its area, under a typical tropical climate, with rainy summer and dry winter. The water availability in the soil under cerrado vegetation is not constant neither uniform due to the great rain fluctuations and also because the vegetation is very scattered. This work shows the establishment of a cerrado tree species Dalbergia miscolobium Benth., from seeds, taking into account the rain fluctuations at which the seeds are submitted since fruit dispersion which occurs during the dry season. The fruits, dispersed in May, remained in the soil with viable seeds until the beginning of the constant rainfall, in September, when started the major seedling emergence. Seed viability, seedling emergence and survival were better when the fruits were protected from the direct radiation, kept buried and/or under shade and in a place without herbivores. Occasional rainfall during the dry season also allowed seedling emergence, but the survival was zero because the inadequate water availability for seedling growth.
