With the objective to evaluate the percentage of seedlings emergence and the emergence velocity index (EVI) of longan (Dimocarpos longan Lour) seeds, was carried out the present research, using plants that came from the Germplasm Bank of the Department of Vegetable Production of the Faculdade de Ciências Agrárias e Veterinárias - UNESP - Campus of Jaboticabal, São Paulo state, Brazil. Immediately after the extraction, the seeds were washed, dryed and sowed in sand seed beds. The experimental delineation was entirely randomized, with three treatments, characterized by the size of the seeds: big, medium and small, determined by the medium weight of 50 seeds (in grams), being: 89; 80 and 65g respectively. The values of percentage of emergence were transformed in arc-sen square root (X / 100). The averages were compared by the test of Tukey, with 5% of probability. It was not observed significantly difference to the evaluated parameters, being obtained the values of the percentage of emergence of 97 to 91% and EVI of 0,651 to 0,680, showing that the size of the seed is not a factor to be considered for this specie.
