Hormones and Post-Harvest Technologies Quiz

Which hormone is primarily responsible for cell elongation in plants?

• Ethylene

• Auxins

• Cytokinins

• Abscisic acid

Gibberellins are known to:

• Inhibit seed germination

• Promote fruit ripening

• Stimulate stem elongation

• Cause leaf abscission

Which hormone is commonly used to delay the ripening of fruits during transport?

• Ethylene

• Abscisic acid

• Cytokinins

• Gibberellins

Ethylene is primarily associated with which of the following processes in plants?

• Seed dormancy

• Flowering

• Fruit ripening

• Root growth

Cytokinins are known to:

• Promote cell division

• Inhibit root growth

• Induce leaf senescence

• Cause fruit drop

Which hormone is used to induce flowering in some plants?

• Auxins

• Gibberellins

• Ethylene

• Abscisic acid

The use of auxins in plant production can help in:

• Delaying fruit ripening

• Promoting root formation in cuttings

• Inhibiting seed germination

• Inducing leaf fall

Which hormone is often used to promote the ripening of fruits like bananas and tomatoes?

• Cytokinins

• Gibberellins

• Ethylene

• Abscisic acid

Abscisic acid is primarily involved in:

• Promoting seed germination

• Inducing dormancy

• Stimulating stem elongation

• Enhancing fruit ripening

Which of the following is a key process in post-harvest technologies?

• Photosynthesis

• Pollination

• Ripening

• Transpiration
