Uses of Plant Hormones

The video explores the diverse applications of plant hormones, including auxins and gibberellins, in agriculture and gardening. It explains how auxins are used in selective weed killers to target weeds without harming crops. Growth hormones are also used to promote plant growth by aiding root development in cuttings. The video discusses controlling fruit ripening using hormones to ensure optimal ripeness for consumers and creating seedless fruits. Additionally, it covers managing seed dormancy to enable year-round germination and using ethylene to promote fruit ripening through a positive feedback loop.
