Commercial use of plant hormones

How are plant hormones used in agriculture?

They are used to control growth, promote root formation, control flowering, and regulate fruit ripening.

What is the use of auxins in agriculture?

Auxins are used in rooting powders to stimulate root growth in cuttings and to promote fruit development.

How are gibberellins used commercially?

They are used to promote seed germination, increase fruit size, and improve the uniformity of crops.

How does ethylene help in the commercial production of fruit?

It is used to control the ripening of fruits, allowing for better control of harvest and sale time.

How are cytokinins used in plant tissue culture?

They are used to promote cell division and the growth of shoots in cultured plant cells.

What is the role of abscisic acid in crop management?

Abscisic acid can be used to promote drought resistance by closing stomata and inhibiting growth.

How are synthetic auxins used to control weeds?

Synthetic auxins are used in herbicides to cause uncontrolled growth and death in broadleaf weeds.

What are some environmental concerns related to the use of plant hormones?

Overuse of synthetic hormones can disrupt local ecosystems and affect non-target plant species.

How do plant hormones improve crop yield?

By regulating growth and development, plant hormones can increase fruit size, improve germination rates, and extend shelf life.

How are plant hormones used to produce seedless fruits?

Gibberellins and auxins can be applied to plants to prevent the formation of seeds, creating seedless fruit.

How does cytokinin affect tissue culture?

Cytokinins are essential for the development of shoots and the overall growth of cultured plant tissues.

How is ethylene used to control flowering?

Ethylene is used in some crops to induce flowering at specific times to synchronize harvesting.

What is the effect of plant hormones on plant defense?

Some plant hormones like jasmonic acid regulate plant responses to herbivory and pathogen attack.

How do plant hormones help in reforestation projects?

They can be used to encourage rapid root and shoot growth, aiding the establishment of saplings in reforestation efforts.

What is the future potential for plant hormone use in agriculture?

Advances in biotechnology may allow for more precise control over plant growth, leading to higher yields and more sustainable farming practices.
