The chemical Gibberellic Acid (GA3) , is used in commercial horticulture to improve plant growth and yields.


Can be used safely on fruit, vegetables, and leaf crops.

Products are safe to eat, crop and harvest after plant treatments at recommended concentrations.
Natural organic product. Breaks down naturally as plants grow.

This plant growth regulator can be found naturally in plants. Used on a wide range of food crops worldwide.

Routinely used for the production of seedless grapes in Europe, USA, Australia, South Africa and South America.

Classified as a plant growth regulator it can have a number of commercially important effects on how plants grow.

Gibberellic Acid can affect growth by its effect on cell growth and cell elongation. Such effects are often seen in stem growth as well as root growth. Stems and inter nodal lengths can be increased and a better more extensive root system develop. Increases in cell division can also sometimes be seen in the production of larger leaves. GA leads to bigger plants with bigger shoots and leaves in many plants.

 

Bigger plants produce bigger crop yields.

 

Gibberellic acid can be used as a seed dormancy breaker. It is most effective on rosette plants that have a cold dormancy requirement for germination. Though dormancy breaking and germination improvement can be seen in a number of genera.

Germination seed dormancy of a number of Carnivorous or insectivorous plants can be broken by using a solution of Gibberellic Acid.

Used for the production of standard and half standard plants. Can be used on Fuchsia, Rose, Hibiscus (both hardy and tropical varieties), Ficus, Vitis, and a range of fruit crops when a strong stem is trained to a cane to build a framework.

Longer flower stems can be produced on a range of 'florist' flower crops. In addition flower size can sometimes be achieved. Treating flower buds before opening with a solution of Gibberellic acid can lead to huge flower increases in a range of different flowers.

Science and horticulture use Gibberellic Acid for the following benefits in a range of plants. Now also available for hobbyists and enthusiastic amateurs or anyone who grows plants. It is easy to mix, use and apply to plants growing anywhere.

The chemical composition.

Gibberellic Acid GA3

common alternative names: Gibberellin, GA3, Gibb Acid.

C19H2206 Molecular Weight: 346.37 Melting point 230degC.

White powder, store in the dark. For prolonged storage keep at 2-8 degC. Keep cool for long term storage for 2 years

Low toxicity, safe to humans and animals after usage. No phytotoxicity at standard application rates Avoid eye contact at all time, Avoid ingestion or inhalation. Mild irritant to skin. Always wash with large volumes of water in case of contact.

Limited solubility in water. It will dissolve slowly over 24 hours in water. Slight heating by resting tube of water and GA3 mix in boiling water will help. (For many years we used to routinely dissolve GA3 in water for treating Nicotiana clevelandii and Arabidopsis seed) It is simple and very quick.

Dissolve in alcohol, isopropyl alcohol, ethanol, acetone, chloroform. Avoid excessive heating while mixing in the light of decreased activity post autoclaving when used in-vitro.

Store in a cool dry dark place. We supply in a leak proof container and we suggest Triacontanol is stored in the dark in a refrigerator at 2-8deg C. Foil cover the tube if necessary to eliminate light. We suggest using the solution soon after mixing and preferably use within a few days.

For in-vitro use of GA3 we suggest the use of aseptic filtering and adding to plant media after autoclaving. There is some evidence that GA3 activity decreases if it has been autoclaved.

Rates of usage.

For treatment of seed to break dormancy (seeds that are susceptible) use at rate of 200ppm to 500ppm. Sometimes 1000ppm solutions can be used, however this can on occasions lead to problems with seed elongation in some genera, after the germination process. Seeds can be soaked for 2-24 hours.

For increasing flower size by flower bud treatment. Concentrations can vary but generally low concentrations of 10-50 ppm are used. For Camellias concentrations of 20,000 ppm can by used in a technique called 'Gibbing'.

For treating adult plants and seedlings to increase growth, use at a rate of 10 -200ppm for most genera. Solutions should be applied as a foliage spray aiming for drip down coverage. There is a great deal of variation in plant responses to concentration. Generally vigorously growing plants under warm conditions require larger larger volumes of Gibberellic acid. It is important to also feed your plants with fertiliser when using a Gibberellic treatment.

Mixed solutions should be stored in a refrigerator at 5-8degC and discarded after 7 days as it does not keep long term as a water mixed solution.

Mixing the chemical Gibberellic Acid GA3 to use.

Information on concentrations is available in this section see above.

.As a dilution example: How to make a 100ppm Gibberellic Acid solution for spraying foliage.

100ppm is equivalent to 100mg/1000ml (1.0litre).

Weigh 100mg GA3 powder.( A cheap portable battery electronic digital scale is easy to use and widely available on the internet or eBay) * see section below if wanting to estimate!

Dissolve powder in a small volume of alcohol. 5-10ml. Alcohol solvents listed above. The solution may need slight heating to improve solubility. Take care with flammable liquids!. Avoid excessive heating. A pyrex test tube is ideal to mix this in.

Measure 1000ml (1.0litre) of good quality water and to this add the freshly mixed solution. Shake or stir.

Some people add a foliage wetter such as Physan 20, Add 1-5 drops. If this wetter is not available use liquid hand dish washing soap at 1-5 drops. Adding wetter is optional.

Use an inexpensive hand sprayer to spray your plants with. It is best to shake before each spraying. Aim for coating the upper surface of the plant leaves thoroughly, Spay enough to allow drip down from the leaves. Spray stems and shoots also. Do not spray during bright sunshine. Aim to spray at the beginning of the day, when plants are starting to grow. Do not allow leaves to remain wet overnight.

It is always best to mix and use GA3 solutions when fresh. If this is not possible store this spray solution in the refrigerator at around 5degC. If the solution is cold, remember to bring the solution temperature up to that of the foliage before spraying to stop cold damage to leaves. GA3 solutions loose activity over time and should be freshly made and used.

* If you have no scales and want to estimate. We supply tubes of 2.0gms(2000mg) of GA3.. Simply divide the powder into x20 piles of 100mg, For foliage spraying there is some degree of flexibility on concentrations from 10-200ppm.

Internet information on Gibberellic Acid (GA3)

Information on applications as foliar, bud and seed treatments is available on the www. There are numerous research paper published also. Just be aware that there is a great deal of variation in plant response to this plant growth regulator. Environmental and growing conditions are variable and we urge you to proceed with caution and evaluate your plants at each stage of growth. Remember increased concentrations does not always elicit a better growth response.

 

white-arums gibberellic acid treatment

 

Combination plant growth regulator (PGR) treatments of plants for better results. Gibberellic acid and triacontanol to produce increased flowers

Here the white Arum (Zantedeschia aethiopica) has been treated to combination treatments. Plants are grown large with triacontanol feed in Triaboost then to induce mass flowering they are sprayed with gibberellic acid. Gibberellic Acid at 500ppm is a standard spray treatment to make flower buds. Plants are sprayed x2 early on in the season as a foliage spray and then fed as per normal. If you used excessive GA3 treatment the flowers will be over 5 feet high!

Coloured arum hybrids have become increasingly popular over recent years. Commercial growers will use gibberellic acid treatments by rhizome soaking or foliage sprays to make multiple flowers on these arums. You may want to do the same with your plants.

Internet information on the other growth regulator triacontanol.

Information on applications as foliar, soil drench or in-vitro is available on the internet. Research papers have a high focus on treating plants with foliage sprays of triacontanol. This reflects the high cost of the research grade chemicals which can be x10 the price of triacontanol sold by Triplantanol. Researchers cannot afford to wash expensive grade triacontanol into and out of pots in high volume research projects!
