Describe how gibberellins and ethene are used commercially in the food industry. In your answer, refer to the role of each hormone.

Gibberellins are plant hormones that trigger seed germination. Commercially they are added to barley in brewing and malting to stimulate growth and improve malt quality, and they are used to produce seedless fruit and increase fruit size in horticulture.
Ethene (ethylene) is a gaseous hormone that controls the ripening of fruits. In the food industry it is applied to unripe fruit, such as bananas, to induce ripening during or after transport, ensuring fruit reaches consumers at the desired stage of ripeness.
