Gibberellic Acid (GA3) Solution is a powerful plant growth regulator that supports healthy development in tissue culture by stimulating growth processes such as germination, elongation, and fruit formation.

Key Benefits of the GA3 Solution

• Breaks seed dormancy and encourages germination

• Stimulates stem elongation through enhanced cell expansion

• Promotes cell division and supports fruit growth

• Helps release buds from dormancy for continued plant development

How to Use the GA3 Solution

Follow these steps to prepare your tissue culture media with PCT’s GA3 solution:

1. Prepare your liquid tissue culture media using PCT’s MS, DKW, or another suitable medium based on your plant species.

2. Add sugar depending on the volume (typically 30 grams per litre), 1 ml/L of PPM, and either 3–4 g/L of gellan gum or 6–8 g/L of agar.

3. Add the required amount of GA3 solution.

4. Autoclave the medium for 20 minutes at 121°C and 15 psi.

5. Your media is now ready for use!

To use the Gibberellic Acid (GA₃) 1000 ppm stock solution for seed germination, dilute it with clean or distilled water according to the needs of your seeds. Mix 1 mL of the GA₃ solution with 9 mL of water to make a 100 ppm solution suitable for most seeds, 1 mL of solution with 3 mL of water for a 250 ppm solution for older or tougher seeds, and 1 mL of solution with 1 mL of water to make a 500 ppm solution for very hard-to-germinate seeds. Soak the seeds in the prepared GA₃ solution for 12–24 hours, then rinse them gently with clean water and sow immediately into your preferred growing medium. Always prepare a fresh solution before use, as GA₃ breaks down over time, and store the stock bottle as per the storage guide on the listing.

We offer both GA3 powder and solution forms of our plant growth regulators to meet different needs:

Powder Form: This is the raw, solid form of the product. It offers a longer shelf life, is cost-effective, and is ideal for customers who prefer to prepare solutions at desired concentrations.

Solution Form: This is a ready-to-use or ready-to-dilute liquid product version. It provides convenience and ensures consistent concentration, saving preparation time. However, it generally has a shorter shelf life and should be stored properly to maintain effectiveness.

Both forms contain the same active ingredient—the choice depends on your application preferences, storage capabilities, and handling needs. We’re happy to assist if you have any questions about usage or preparation.
