Introduction: Plant and Root Hormone

Root Hormone

Root hormone is a type of plant hormone which is used in plant propagation. Naturally, it is synthesized by some species of plants itself. The main function of this type of hormone is to promote the the growth of root cell. Commercially available root hormones (purchasing required) are very useful in agribusiness such as a commercial nurseries.

Plant Hormone

Plant hormone is an active chemical which is involved in physiological activity of a plant. Plant hormones are synthesized inside live parts of a plant e.g., growing shoot and root tips. Some plant hormones are as follows:

• Auxin.
• IBA.
• ABA.
• Gibberellin.
• Cytokinin.

Auxin: Auxin is a growth promoter hormone. It is responsible for height of plant.

ABA: ABA is a growth inhibitors.

Cytokinin: It is responsible for cell division.

Ethylene: It is responsible for fruit ripening.

IBA: It is also a growth promoter.

Gibberellin: It is responsible for development of stem.

Importance

Quick Rooting: Rooting does not occurs in all types of plant or plant species. In some cuttings like bougainvillea and rose, rooting occur naturally. In ornamental plants like junipers and thuja,  success rate of rooting can be increased by the use of commercially available root hormones (powder and liquid form).

Success rate: Success rate is low in traditional cutting method of horticultural plants. More than 50 percent cuttings can die in traditional method. Use of hormone decreases the chance of failure.

Formulation: Root hormones are available in both liquid and powder form.

Availability: It can be purchased from any nearby agricultural shop. It can also be purchased online from any E-COMMERCE shop.

Uses

• Air Layering
• Cutting
• Inter-nodal treatment

Air Layering

Air layering is a plant propagation technique. It is performed on the attached branches of a plant/tree.

How to use it?

Follow these steps:

• Take a knife
• Select a branch
• Remove the bark between two nodes or 2.5 inch.
• Thoroughly  paste the exposed wooden part with root powder.
• Cover the peeled portion using soil media.

Cutting

Cutting is a simple method of plant propagation. Cutting is a common propagation method used in some ornamental plant species.

How to use it?

• Take a grafting knife.
• Cut a small branch
• Dip it in hormone formulation.
• Place it in growing media.

Inter-nodal treatment

Internodes are physical joints found in a creeper or a plant like maize. Betel Vine is creeper plant which produces roots at internode.

Application

• Academic research
• Commercial application
• Home application

Academic research

Academic research works include M. Sc. Agriculture Research Work and Ph. D. research work.

Commercial application

More amount of the chemical is required in commercial plant production. Use of root hormone in a plant nursery or other farm is commercial application.

Home Application

It is done in ornamental plants.

Types of Root Hormone

Two types of root hormones are available, first is naturally synthesized hormones found inside a plant and second is commercially prepared products.

Naturally synthesized root hormones:

• IAA (Indole Acetic Acid)
• IBA (Indole Butyric Acid)

Commercially prepared products: Commercially prepared products are made inside a laboratory. These products include a proper media, active chemical (hormone). Some commercial products containing root hormone are as follows:

1. Rootex
2. Fast Gro
3. Root Boost etc.

Where to Purchase Root Hormone?

1. Online: E- commerce websites.
2. Agricultural shops.

Price: Price range varies from 150 to 10000 rs. depending on quantity and brand.
