Growing cuttings. Cuttings develop much bigger root systems if they are dipped in hormone rooting powder or planted in rooting compound containing growth hormone - making it possible to clone plants quickly and cheaply.
* Producing fruit without seeds. To do this, growth hormones are sprayed onto unpollinated flowers to make them grow fruit without fertilisation.
* Ripening fruit. The plant hormone ethene is sprayed on fruits to make them ripen fast and all at the same time before harvesting. Bananas are harvested before they are ripe to reduce damage to them during transport, and then sprayed with ethene to ripen them.
* Increasing the size of fruit. For example, grapes are sprayed with the hormone gibberellin to increase the size of the fruit.
* Controlling weeds. Some synthetic weed killers which selectively kill unwanted plants contain growth substances that speed up the metabolism. As a result weeds like dock and dandelion grow so fast that their food and water supply cannot keep up, so they run out of energy and die

∙ 11y agoPlant hormones can be extracted or artificially reproduced by humans, rooting powder or selective weed killers contain hormones. The rooting powder contains auxins which speed up growth and the selective weed killers contain growth hormones which can disrupt growth in specific weeds/plants.

∙ 10y agoPlant hormones are used to control the growth characteristics of plants. For examples hormone treatment is used to encourage rooting, or to stunt the growth of the plant or to encourage lateral branching; these are all techniques used by horticulturists to produce good quality, saleable plant materials
