Factor II is a seed storage duration: without being stored, 1, 2, 3 months. Analysis of the data using linear quadratic regression method. The experimental results show that the interaction between seed storage time and concentration of sulfuric acid solution on seed germination, growth speed of seeds, and seed vigor. Without storage time and concentration of sulfuric acid solution 0.75% gives the best effect compared to other treatments. At the time of storage, followed without the optimum sulfuric acid concentration as much as 0.783% gives the percentage of seed germination was 93.521%.
