Acca sellowiana O. (Berg ) Burret is a species native from southern of Brazil and Uruguay which has great potential for use in the recovery of native forests and degraded areas. The aim of this study was to evaluate the morphology of Acca sellowiana O. Berg seeds by analysis of X-ray images and correlate the results with seed germination. Acca sellowiana O. Berg seeds, represented by three lots, were analyzed by X-ray test and later the same seeds were submitted to the germination test, with assessment at 44 days after sowing. X-ray images were analyzed with ImageJ software. X-ray test allows Acca sellowiana internal morphology seeds visualization. Seed image analysis allows the measurement of internal seed areas and assists in the study of relationships between seed morphology and germination. The seed internal free space and the presence of damages can affect germination.
