GCSE Biology - Plant Hormones - Uses of Auxin, Gibberellin and Ethene #53

The video tutorial explores the commercial applications of plant hormones: auxin, gibberellin, and ethene. Auxins are used to stimulate plant growth, aid in rooting, and act as selective weed killers. Gibberellin helps control seed dormancy, induce flowering, and increase fruit size, especially in seedless varieties. Ethene is crucial for controlling the ripening of fruits, allowing for better timing in transportation and sale. These hormones enable farmers to optimize plant growth and production cycles.
