The various plant hormones and their functions include germination of seeds, growth of the plant and producing flowers and fruits. Gibberellins are a group of compounds that are found in plant cells that help in its development.
There are approximately 126 types known till date. This hormone is produced in the plant's body through the process of biosynthesis. It is also used as plant food, in the form of acid.
The Association Between Gibberellic Acid and Plant Growth
Gibberellin was first discovered in the year 1926, when a group of Japanese botanists came across some rice crops that were abnormally high and would be unable to stand tall, weighed down by excess grains. On closer examination, it was discovered that the rice crop was 'infested' with fungi.
This fungal infestation was responsible for this uncontrolled growth of the crop. The fungus was separated from the plant for further examination and gibberellic acid was thus discovered in the year 1935 for the purpose of agriculture.
Gibberellin, which is used for agricultural purpose, is a hormone that is extracted from the Gibberella fujikuroi fungus. This acid is also known by other names like Gibberellin A3, GA3 or simply GA.
The compound undergoes the process of purification and gives a pale yellow-colored powder as the end product. This is then used to treat plants and increase the production of fruits or flowers. This compound is also available in liquid form.
The popular seedless variety of grapes is the byproduct of the use of gibberellic acid. This compound helps plants produce seedless fruits that are fully matured. The crop yield is also increased.
Though gibberellin naturally occurs in plants, it is in small quantities. Gibberellic acid, manufactured for gardening and agricultural purposes, is used to induce the plants to produce more fruits.
Using this commercially produced plant hormone on the plants can yield better variety of fruits and vegetables that are much bigger and juicer than the other varieties, that have not used gibberellin.
Other advantages of this plant hormone is that when used on a wilted plant, the plant may regrow again. This is because ingredients in this processed plant hormone are easily absorbed in the plant's body and begin the action of reconstruction of the dying plant cells.
In order to purchase it, you can contact your nearest nursery or gardening store. A plant specialist will also guide you on the appropriate dosage to be administered to the plant.
