The tests were conducted at the Laboratory of Seed Analyzes of the Federal Univer-sity of Paraíba, in the city of Areia-PB. The seeds of L. operculata were submitted to scarification treatments with sandpaper, cutting with scissors, imbibition in cold water, immersion in hot water and immersion in sulfu-ric acid. In evaluating the effect of treatment, was determined percentage, first count and germination index speed as well as length and dry mass of roots and hypocotyl.
