Forchlorfenuron is primarily used to promote fruit enlargement and improve crop yields by stimulating cell division and delaying fruit abscission. It is applied as a foliar spray or dip treatment during early fruit development stages in grapes, kiwifruit, and cucurbits. Researchers also employ Forchlorfenuron in plant tissue culture to induce callus formation and enhance shoot proliferation. Its cytokinin-like activity makes it valuable for studying plant growth mechanisms and stress responses.
