Gibberellins are plant hormone that play important role in plant growth, flowering, and germination.

Examples of Gibberellin

Here are some examples of Gibberellins:

1.    Gibberellin A1 (GA1) 

GA1 is one of the most important example of gibberellins. It is first gibberellins discovered and is known for its role in promoting stem elongation in plants.

2.    Gibberellin A3 (GA3) 

GA3 is used in agriculture to promote fruit growth, particularly in seedless grapes and other fruit varieties.

3.    Gibberellin A4 (GA4)

GA4 plays a role in seed germination and stem elongation, contributing to overall plant growth.

4.    Gibberellin A7 (GA7) 

GA7 is involved in the regulation of flowering in some plant species, promoting the transition from vegetative to reproductive growth.

5.    Gibberellin A9 (GA9)

GA9 is known for its role in promoting the elongation of internodes (segments between leaves) in plants.

6.    Gibberellin A19 (GA19) 

GA19 is important in the biosynthesis of other gibberellins and is a precursor for the production of active gibberellins in plants.

7.    Gibberellin A20 (GA20) 

GA20 is another precursor in the gibberellin biosynthesis pathway, contributing to the production of active gibberellins.

8.    Gibberellin A29 (GA29) 

GA29 is involved in promoting stem elongation and the overall growth of plants.

9.    Gibberellin A44 (GA44) 

GA44 is a gibberellin that influences flowering and fruit development in certain plant species.

10. Gibberellin A53 (GA53)

GA53 is a gibberellin that plays a role in regulating plant growth and development, including seed germination and stem elongation.
