Examples

• Gibberellins cause dramatic stem elongation in many plant species.
• The seeds were treated with gibberellins to promote faster germination.
• Rice plants deficient in gibberellins remain unusually short.
• Researchers discovered that gibberellins play a key role in breaking seed dormancy.
• The application of gibberellins increased the height of the dwarf variety.
• Gibberellins work together with other plant hormones to regulate growth.
