Question

What is the name of the plant hormone that causes fruit to ripen?

Answer 1

Plant hormones:

1. Plant hormones are simple organic compounds that are delivered by xylem, phloem, or diffusion.
2. They are manufactured in one section of the factory and transferred to another.
3. Plant hormone production does not require any specific organs.

The hormone responsible for the ripening of fruit:

1. Abscisic acid (ABA) and ethylene are the primary regulators of fruit ripening and senescence.
2. Ethylene is well-known for its role in plant age, including fruit ripening and flower and leaf senescence.
3. Ethylene is a gaseous plant hormone that causes fruit to mature.
4. It is abundantly synthesised in the fruits and tissues undergoing ripening and senescence, respectively.
5. Ethylene promotes the ripening of fruits such as tomatoes, lemons, and oranges. It also has the effect of increasing the rate of breathing.
6. It also controls abscission and senescence.
7. It is also in charge of breaking dormancy.
8. Ethylene is widely utilised in agricultural applications.
9. Abscisic acid stimulates the synthesis of ethylene.
