the most important function of gibberellic acid?

Answer 1

It is an auxin that is produced to make the plant grow towards the sun or light source. That is why you see some plants with things blocking the light and it bends to go towards the light It causes the side with out the light hitting it to grow more than the side with the light, that is how the bend is created

Answer 2

This is a hormone, (C19H22O6), obtained from the fungus Gibberella fujikuroi and used to promote the growth of plants, especially seedlings.

Gibberellic acid is a simple gibberellin, promoting growth and elongation of cells. It affects decomposition of plants and helps plants grow if used in small amounts, but eventually plants grow a tolerance for it. Gibberellic acid stimulates the cells of germinating seeds to produce mRNA molecules that code for hydrolytic enzymes.

It was first discovered in Japan in 1935 as a result of the study of a condition common in rice plants called "foolish seedling" disease, which caused the plants to grow much taller than normal. The effects of gibberellins weren't widely understood until years later.

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 0.01-10 mg/L.

Gibberellic acid is sometimes used in laboratory and greenhouse settings to trigger germination in seeds that would otherwise remain dormant.

Gibberellins have a number of effects on plant development. They can

1) stimulate rapid stem growth,
2) induce mitotic division in the leaves of some plants,
3) increase seed germination rate.

Answer 3

friend here are the few important function of gibberellic acid:

Stimulate stem elongation by stimulating cell division and cell elongation.

Stimulates bolting/flowering in response to long days.

Breaks seed dormancy in some plants which require stratification or light to induce germination.

Stimulates enzyme production (a-amylase) in germinating cereal grains for mobilization of seed reserves.

Induces maleness in dioecious flowers (sex expression).

Can cause parthenocarpic (seedless) fruit development.

Can delay senescence in leaves and citrus fruits.
