What are the physiological functions and applications of gibberellins?

1. Gibberellin Promote cell division and differentiation. Mature cells grow longitudinally, elongating the fruit stalk and thickening the peel.
2. Gibberellin Promote the biosynthesis of auxin. They are mutually synergistic and have certain antidote effects.
3. Gibberellin can induce and increase the proportion of male flowers, regulate the flowering period, and form seedless fruits.
4. Gibberellin can Elongate the internode cells, which has no effect on the roots but has an effect on the stems.
5. Gibberellin Prevent organs from falling off and breaking dormancy, and preserve flowers and fruits.

In addition, we have compiled 10 application points:

1. Gibberellic acid can only elongate cells and cannot be used as a substitute for fertilizer.
2. Gibberellic acid is acidic and turns red when exposed to sulfuric acid. It cannot be mixed with alkaline pesticides.
3. Gibberellic acid can be dissolved in alcohol. It will decompose easily after entering water and cannot be left for a long time.
4. Temperatures below 20 degrees will affect the performance of gibberellic acid.
5. Gibberellic acid is different from auxin and will not inhibit growth at high concentrations.
6. The buds, roots, fruits and seeds of plants all contain gibberellic acid, so it is difficult for seedless fruits to expand.
7. Gibberellic acid can be transported in both directions, up and down. Excessive use will cause excessive growth.
8. The excessive growth caused by gibberellic acid can be alleviated by paclobutrazol.
9. Gibberellic acid can be sprayed, applied for seed dressing and root dipping.
10. Gibberellic acid can work better when used in conjunction with other regulators and nutrients.
