Gibberellins are a group of plant hormones that play a crucial role in regulating growth and development. They help seeds germinate, promote stem elongation, and influence flowering. By breaking dormancy in seeds, gibberellins allow plants to grow when conditions are favorable, ensuring their survival and reproduction. These hormones are produced in various parts of the plant, including roots, leaves, and fruits. Gibberellins are also used in agriculture to enhance crop yields and improve fruit quality. For example, they can make grapes grow larger and help barley produce more malting grains, benefiting both farmers and consumers.
