What is the concentration of IBA for rooting?
We found that 2 g.L−1 (2,000 ppm) indole-3-butyric acid (IBA) in a 50% ethanol solution is the best concentration for rooting cuttings of a range of sizes, and that rooting declines with increasing basal diameter of stems, but increases with increasing length of stem.
How do you dissolve indole butyric acid?
Since IBA is not completely soluble in water, it is typically dissolved in 75% or purer alcohol for use in plant rooting, making a solution of between 10,000 and 50,000 ppm. This alcohol solution is then diluted with distilled water to the desired concentration.
How do you use IBA for cuttings?
Spray the aqueous IBA rooting solution on the cuttings at the same rate as the original useful rate or lower. Tissue culture plantlets do not have stomata, therefore, foliar application is not appropriate. Before planting, Total Immerse the plantlets in the aqueous IBA rooting solution for a few seconds.
What is IBA solution?
IBA dissolved in water is a useful growth regulator for the plant grower and propagator. It is used for rooting of plant cuttings by Dry Dip, Total Immerse.
How do you prepare IBA hormones?
Add 1.0 g of Indole-3-Butyric acid (IBA, GoldBio Catalog # I-180) to a 100 mL flask or beaker. 2. Add 2.0-5.0 ml of Ethyl Alcohol (EtOH) or 1N NaOH to dissolve the powder. Bring volume to 100 ml with molecular biology grade water.
What is IBA rooting powder?
What is IBA? IBA stands for Indole-3-butyric acid and it is a naturally occurring plant hormone that is used in commercial plant rooting products which is why it is known as a “rooting hormone”. IBA is created by plants and can be produced by soil bacteria. It is available in multiple forms such as gels and powders.
What is the formula to calculate ppm?
PPM is calculated by dividing the mass of the solute by the mass of the solution, then multiplying by 1,000,000.
How do you use indole butyric acid?
Use Sites: Many food and feed crops; ornamental turf and nursery plants Uses: Growth enhancer to increase both yield and quality. Application Methods: Applied to soil or plants as spray. Also used as a dip for cuttings. With the exception of certain workers, no harm is expected from use of indole-3-butyric acid.
What are the ingredients of rooting hormone?
The active ingredient is indolebutyric acid (IBA) which is a synthetic rooting chemical that is widely used because it promotes root development in a wide variety of plants without being toxic to the plant.

What is indole-3-butyric acid?
Indole-3-butyric acid ( 1H-indole-3-butanoic acid, IBA) is a white to light-yellow crystalline solid, with the molecular formula C 12 H 13 NO 2. It melts at 125 °C in atmospheric pressure and decomposes before boiling. IBA is a plant hormone in the auxin family and is an ingredient in many commercial horticultural plant rooting products.
How do you make plant hormone from IBA?
Plant hormone. Since IBA is not completely soluble in water, it is typically dissolved in 75% or purer alcohol for use in plant rooting, making a solution of between 10,000 and 50,000 ppm. This alcohol solution is then diluted with distilled water to the desired concentration. IBA is also available as a salt, which is soluble in water.
