Thidiazuron (TDZ) is a phenyl urea derivative used as a plant growth regulator to stimulate shoot induction and cell division in plant tissue culture. This 250mg formulation is effective in promoting the growth of plantlets from explants, particularly in woody species and other difficult-to-propagate plants. TDZ acts by influencing cytokinin-like pathways in plant tissues, promoting cell division and facilitating the formation of new shoots. It is often used in combination with other growth regulators to optimize tissue culture protocols. Thidiazuron is an essential tool in the production of transgenic plants, micropropagation, and genetic research in agriculture and horticulture.
