What is Gibberellic Acid?

Gibberellic acid is a naturally occurring plant hormone that can also be artificially synthesized. It functions similarly to endogenous plant hormones, regulating various physiological processes in plants. Unlike some other gibberellins, gibberellic acid is readily absorbed by plants through their leaves, flowers, stems, and seeds, then transported to actively growing parts to exert its effects.

The Amazing Functions of Gibberellic Acid

  1. Promoting Fruit Enlargement and Seedless Fruit Formation
    In grapes, spraying 4-6 ml/L gibberellic acid on flower clusters before blooming or 10-20 ml/L on young fruits after flowering can significantly promote fruit enlargement and even achieve seedless fruit production, increasing yield and improving quality.
  2. Enhancing Vegetative Growth
    For grape seedlings, spraying 50-100 ml/L gibberellic acid twice with an interval of about 10 days can effectively accelerate seedling growth, leading to stronger and healthier plants.
  3. Improving Seed Germination Rate
    Treating wheat seeds with 5-10 ml/L gibberellic acid solution by soaking for 8 hours and then sowing can greatly enhance the germination rate, ensuring a more uniform and vigorous crop stand.
  4. Extending Freshness
    After harvesting cucumbers, applying 10-50 ml/L gibberellic acid solution can significantly extend their freshness, reducing post-harvest losses and maintaining quality for longer periods.
  5. Regulating Flowering
    Spraying 50-100 ml/L gibberellic acid on plants at the 1-leaf stage can help regulate flowering, increasing the number of female flowers and thus improving fruit-setting rates.

Wide Applications in Agriculture

Gibberellic acid finds extensive use across a wide range of crops, including economic crops like corn, rice, and cotton; fruits such as grapes, strawberries, oranges, pineapples, bananas, and pears; and vegetables including cucumbers, eggplants, tomatoes, watermelons, celery, spinach, lettuce, and potatoes. Its versatility makes it an indispensable tool in modern farming.

Important Usage Notes

  • Avoid Mixing with Alkaline Substances: Gibberellic acid decomposes in alkaline conditions, so it should not be mixed with alkaline foliar fertilizers or pesticides.
  • Proper Dissolution: Due to its low water solubility, gibberellic acid should first be dissolved in alcohol before adding the required amount of water for use.
  • Follow Concentration Guidelines: Strictly adhere to the recommended concentration in the user manual. Excessive concentration may cause phytotoxicity.
  • Prepare and Use Immediately: Gibberellic acid solutions should be prepared fresh and used immediately; do not store them overnight.

In conclusion, gibberellic acid is a powerful ally in agriculture, but its effectiveness depends on proper use and combination with adequate water and fertilizer management. By harnessing the benefits of gibberellic acid correctly, farmers can significantly improve crop yields, quality, and overall agricultural productivity.
