Gibberellic acid is a plant hormone that regulates growth and influences various developmental processes, including seed germination, dormancy, and flowering. The role of Gibberellic acid in breaking seed dormancy has been well documented in several studies. It helps in the elongation of cells, division of cells and also helps in breaking seed dormancy.
