How can gibberellin cause some dwarf plants to grow to normal size?

Gibberellins are a class of naturally occurring plant hormones that play a vital role in regulating growth and development. They influence the rate of cell division within the meristems—the regions of a plant where new cells are produced—and are particularly effective at promoting the elongation of main stems.123

In many compact or dwarf plant varieties, the application of gibberellin can stimulate significant growth, effectively transforming them into normal-sized plants. This occurs because these hormones help overcome internal growth limitations, such as those caused by genetic factors that might otherwise restrict a plant's height or structure. While the exact mechanisms of how these hormones interact with specific genetic pathways are complex, their ability to trigger cell division and elongation allows for the rapid expansion of plant tissues.423
