What does Gibberellins (GA) mean?
Gibberellins are the plant hormones that promote germination, stem elongation, and leaf development. They are also instrumental in determining dormancy, sexual reproduction, and flowering.
Triggered by soil temperature, moisture, and season, gibberellins are stimulated and released, and then guide the plant through the entire life cycle process. They act as the chemical messengers that trigger and control germination and growth.
More Info On Gibberellins (GA)
A major effect of gibberellins is the degradation of the DELLA proteins that act as growth inhibitors during the dormancy stage. By reducing the effects of the DELLA proteins, gibberellins stimulate the beginning of the growth process for the growing season.
Once gibberellins are stimulated and released a seed germinates and sprouts. The gibberellins time and regulate the plant’s growth at an appropriate rate and proportionate to the root system.
A plant without gibberellin hormones would grow uncontrollably, not knowing when to form additional buds, leaves, blooms, or seeds.
Gibberellins trigger the plant’s ability to elongate stems to the proper length and develop leaves properly. They also help with the formation and maturation of blooms, seeds, and bulbs.
