Thidiazuron solution is widely used in agriculture as a plant growth regulator. It promotes uniform flowering in crops like cotton, helping to synchronize bloom periods which improves harvest efficiency. It is also applied to defoliate cotton plants before harvesting, reducing leaf residue and improving fiber quality. In tissue culture, thidiazuron enhances shoot formation and callus induction in various plant species, making it valuable for micropropagation. Additionally, it can break seed dormancy and stimulate germination in certain hard-to-germinate species. Its ability to influence cell division and differentiation makes it useful in forestry and horticulture for clonal propagation of trees and ornamental plants.
