This study had as its objective the determination of ideal procedure of drying and the substrate to evaluate the vigour and the initial growth of surinam cherry seedlings (Eugenia uniflora L.). The used design was entirely randomized in factorial scheme 2 x 4 (2 procedures of drying: shade and sun; 4 substrates: sand, vermiculite, coconut fiber and paper towels) with four replications of 25 seeds each. The following parameters were also analyzed: average time of germination, length of primary root and epicotyl and dry weight of the seedling. The experiment was conducted in BOD regulated at constant temperature of 25 °C and regime of continuous light. The shade method of drying and the vermiculite substrate can be recommended to test the vigour of this specie.
