Resumo: The production of genetically improved seed of Eucalyptus spp requires more detailed research on the nursery practices in order to avoid seed losses. Eucalyptus urophylla and Eucalyptus grandis seeds were processed by hand and by a gravity separator to get the desired separation of light and small seeds from those heavy and large. Each fraction obtained from the separation by hand and by the gravity separator was utilized in the pellenization process. The celofaz and the hiperfosfate were eficient respectivelly as adesive and as inert material. Separation by gravity reduced the number of pellets without seed due to the increase of the purity. Fraction medium and heavy were not significant and the utilization of both can be done. The pellets formed with the smallest seeds (fraction light and small ) were worse than those heavy and medium. Germination rate decreased with the icrease of the pellet size probably due to the barrier developted by the pelletization, showing the existance of a limit to the pellet size.
