Role/effects/importance of Gibberellins in plants

Gibberellins is class of growth promoters produced particularly in young epical leaves (possibly in chloroplasts), buds, seeds, and root tips.  They fall into a group of chemical compounds called terpenes. Role of gibberellins in plants

1. Promotes stem and root elongation thus, genetically dwarf varieties of peas and maize are restored to normal growth and dwarf beans can be converted into runners by application of gibberellins.
2. Mobilize enzymes that release nutrient reserves in grass seeds.
3. they stimulate the growth of side branches from axillary buds
4. they break dormancy and promotes germination of seeds
5. promotes bolting and flowering in long-day plants
6. promotes the growth of lateral buds
7. promotes the development of seedless fruits (parthenocarpy)
