Thidiazuron (TDZ) is a synthetic plant growth regulator that exhibits potent cytokinin-like activity, influencing plant growth and development. It is widely used as a defoliant in cotton cultivation, facilitating mechanical harvesting by promoting the natural separation of leaves from stems . Additionally, TDZ is employed to enhance fruit setting and expansion in various crops, including apples, grapes, and melons, by stimulating cell division and delaying leaf senescence . Mechanistically, TDZ is believed to act by inhibiting cytokinin-degrading enzymes, thereby maintaining elevated levels of endogenous cytokinins, which in turn promote cell division and morphogenesis .
