Agriculture Biotech Functions

Auxins

Facilitate flowering in plants

Auxins

Used in the process of plant propagation.

Auxins

Used by gardeners to keep lawns free from weeds. Auxins are widely used as herbicides to kill dicot weeds.

Auxins

Formation of adventitious roots.

Auxins

Prevention of dropping of leaves and fruits at early stages, Fruit set and growth.

Auxin

Regulate xylem differentiation and assists in cell division.

Auxin

Bending toward a light source (phototropism).

Auxin

Downward root growth in response to gravity (geotropism).

Auxin

Promotion of apical dominance (the tendency of an apical bud to produce hormones that

suppress the growth of the buds below it on the stem). Apical dominance may occur in which

the growth of lateral buds is inhibited by the growth of apical buds.

Auxin

These are produced by the apex of root and shoot.

Gibberellins

Delay senescence in fruits.

Gibberellins

Involved in leaf expansion.

Gibberellins

Break bud and seed dormancy.

Gibberellins

Promote bolting in cabbages and beet.

Gibberellins

Facilitate elongation of fruits such as apples and enhance their shape.

Gibberellins

Used by the brewing industry to accelerate the malting process.

Gibberellins

Used as the spraying agent to increase the yield of sugarcane by elongation of the stem.

Gibberellins

In young conifers, utilized to fasten the maturity period and facilitate early seed production

Gibberellins

Helps in increasing the crop yield by increasing the height in plants such as sugarcane and increase the axis length in plants such as grape stalks.

Gibberellins

are acidic in nature.

Cytokinins

Break bud and seed dormancy.

Cytokinins

Promotes the growth of the lateral bud.

Cytokinins

Promotes cell division and apical dominance.

Cytokinins

They are used to keep flowers fresh for a longer time.

Cytokinins

Used in tissue culture to induce cell division in mature tissues.

Cytokinins

Facilitate adventitious shoot formation and lateral shoot growth.

Cytokinins

Promotes nutrient mobilization that in turn assists delaying leaf senescence.

Cytokinins

Helps in delaying the process of ageing (senescence) in fresh leaf crops like

cabbage and lettuce.

Cytokinins

Involved in the formation of new leaves and chloroplast organelles within plant cell.

Cytokinins

Used to induce the development of shoot and roots along with auxin, depending on the

ratio.

Abscisic acid

Stimulates closing of stomata in the epidermis.

Abscisic acid

Helps in the maturation and development of seeds.

Abscisic acid

Inhibits plant metabolism and seed germination.

Abscisic acid

It is involved in regulating abscission and dormancy.

Abscisic acid

It is widely used as a spraying agent on trees to regulate dropping of fruits.

Abscisic acid

Induces seed-dormancy and aids in withstanding desiccation and various undesired growth

factors.

Ethylene

Increases root hair formation and growth, thus aids plant to expand their surface area for absorption.

Ethylene

Affects horizontal growth of seedlings and swelling of the axis in dicot seedlings.

Ethylene

Used to stimulate the ripening of fruits. For example, tomatoes and citrus fruits.

Ethylene

Facilitates senescence and abscission of both flowers and leaves.

Ethylene

Applied to rubber trees to stimulate the flow of latex.

Ethylene

Enhances respiration rate during ripening of fruits.

Ethylene

Promotes sprouting of potato tubers.

Ethylene

Induce flowering in the mango tree.
