The video discusses the applications of three types of plant hormones in agriculture and horticulture: auxins, gibberellins, and ethene. Auxins promote cell growth and are used in weed killers, rooting powders, and tissue cultures. Gibberellins induce germination, flowering, and fruit production, and are used to produce seedless fruits.
