Abstract

The Sansão-do-campo, also known as sabiá, is a plant whose wood has multiple uses, besides its ornamental value. It is used in forestry, for hedges and as forage. The flowers are visited by bees and tree stalk bark is used to treat lung diseases. The Sansão-do-campo seeds have shown germination problems due to tegument impermeability. To study this problem an experiment was carried out with seeds collected in August 2000 in Jussara, Goiás State. Pure seed samples were immersed in sulfuric acid (H2SO4 P. A.) for 0, 5, 10, 15, and 20 minutes and then washed in running water for 10 minutes to remove acid residues. Seeds were dried and then submitted to the standard germination test. Statistical analysis showed that H2SO4 immersion for 10 to 15 minutes resulted in the highest germination rate (98%).
