Abstract:Gmelina (Gmelina arborea Roxb.) seed is a type of seed that have physical dormancy. This is because water and gases prevent by the hard seed coat during the germination process. Therefore, to break dormancy, preliminary treatment in the form of scarification is required, including using sulfuric acid (H2SO4) solution. This study aims to determine the treatment of soaking in a 96% concentration of H2SO4 solution that produces the best germination ability. The study used a completely randomized design method (CR… Show more
