The hormone used commercially to delay the process of ripening and to improve the storagelife of bananas and grapefruits is
Correct answer: B. Gibberellin
- A. Auxin
- B. Gibberellin
- C. Cytokinin
- D. Ethene
Explanation
Gibberellin is the correct answer because it is a plant hormone that plays a critical role in the ripening process of fruits. In commercial settings, controlling gibrellin levels can delay ripening, allowing fruits like bananas and grapefruits to have an extended storage life. The other options, such as auxin, cytokinin, and ethene, have different primary functions related to plant growth and development, but they are not specifically used for controlling fruit ripening in storage.
