Plant Growth Regulators

Gibberellic acid

Gibberellic acid is a very potent hormone whose natural occurrence in plants controls their development.

Since GA regulates growth, applications of very low concentrations can have a profound effect while too much will have the opposite effect. It is usually used in concentrations between 0.01 and 10 mg/L.

Gibberellins have a number of effects on plant development. They can stimulate rapid stem and root growth, induce mitotic division in the leaves of some plants, and increase seed germination rate.

Gibberellic acid is a simple gibberellin, a pentacyclic diterpene acid promoting growth and elongation of cells. It affects decomposition of plants and helps plants grow.

Uses

Gibberellic Acid is ideally utilized in agriculture domain to improvise the growth of different crops like cotton, cucumber, pear, spinach and many more.

It can stimulate plant stem elongation by stimulating cell division and elongation. And it can break seed dormancy, promote germination, and increase fruit setting rate, or cause parthenocarpic (seedless) fruit by stimulating stems of a plant higher and leaves bigger.

The application of gibberellins has signification effect in raising the yield of rice, wheat, corn, vegetable, fruit, etc.
