The acaizeiro (Euterpe oleracea Mart.) is a native palm of the Amazônia and if has detached in the Brazilian agribusiness for the marketing potential of its products, mainly for the palmi to, and the extracted juice of the fruit. With the growth of the cultivated area it made to grow the search of seeds and changes of this palm. The used method more for the propagation of this species is saw seed, therefore the propagation made for I sprout again is of difficult ac complishment. The objective of this work was to verify the ambient substratum influence dif ferent and conditions in the germination of seeds of this species. The experiment was carried through in not controlled ambient conditions in the fishery of the Federal University of Mato Grosso - Campus of Sinop. He was employed a simple test with completely randomized ex perimental design in factorial scheme 3 x 3 (9 treatments), with four replications containing 20 seeds each. The seeds were sown in seed dispersal in box with substrates (sand, coir and vermiculite). Was using empirical methods in three environmental conditions, sombrite with 90%, 0% light, where the trays were wrapped in aluminum foil to prevent the entry of light, the third environmental condition had no incidence of direct light in the treatment, with 100% of shading. After 30 days assessed the percentage of germination, number of germinated seeds and germination speed index (IVG). During the follow-up all substrates and environ mental conditions were efficient, favouring germination. 100% shaded sand treatment was the most efficient in germination; the highest germination speed index was found in the treatment with 100% vermiculite shading.
