This work aimed to study the influence of storage time and seeding environment on inajá seedling emergence, a native Amazon palm tree, naturally found in open areas of transition forests from Roraima state. After harvesting a portion of fruit was processed and targeted for immediate planting and the rest packed in polyethylene bags and stored in a chamber at 18 °C. After beneficiation we sow the inajá diasporas to two centimeters deep in beds containing sand as substrate. We use the experimental design of randomized blocks in 5x2 factorial scheme comprising the storage times (0, 30, 60, 90 and 120 days) and environments (full sun and greenhouse), with four replicates of twenty seeds per plot. We avaluate the moisture content of the seeds, frequency, average time and the index of emergence speed of seeds. The frequencies and rates of speed of inajá seedling emergence were significantly higher in immediate planting seeds sown in a greenhouse, where emergencies have reached 100%. We did not significant differences from the mean emergence time for any of the stores and environments tested, but this time was on average lower in the greenhouse environment. The storage chamber at 18 °C, not only kept the seed moisture as possible the emergence of seedlings in the greenhouse up to 120 days.Keywords: Arecaceae; Conservação; Germinação; Maximiliana maripa; sementes.
