Euterpe edulis Martius is ecologically important in its native biome and threatened by illegal palm heart extraction. Despite the species' relevance, there is still a lack of information about the physiological behavior of its seeds under different germination and storage conditions. The aim of this work is to evaluate conditions of germination and storage of juçara palm seeds in different environments and substrates. Germination test was set in greenhouse and acclimatized room, combined with three substrates: Tropstrato Florestal®; sand and vermiculite, considering the absence and presence of pericarp. A storage test was set in two temperatures of 25°C and 4°C combined to six periods of storage: zero, 14, 28, 42, 56 and 70 days. The experimental design for both tests was completely randomized composed of four replications and 20 seeds each. They were analyzed: index of speed germination; average of seedling length; percentage of germination; relative frequency of germination and the average of germination time. The seeds’ viability was verified by a tetrazolium test (0.05%). Germination test showed that better results are achieved by removing the pericarp from the seeds. At the acclimatized room the treatments with vermiculite showed superior results for the index of speed germination, average of seedling length and relative frequency of germination, whereas the best result for percentage of germination was verified with Tropstrato® substrate. In the greenhouse, the use of Tropstrato® was better for the index of speed germination and average of seedling length. The storage test showed that the treatments stored for fourteen days have the best averages considering the variables analyzed. The findings reinforce the role of the substrate and moisture maintenance in maximizing vigor and emergence. Our results contribute to strategies of conservation and production of E. edulis seedlings, supporting ecological restoration initiatives and the sustainable use of the species.
