Which of the following plant hormone is associated with the induction of flowering in pineapple?
Show Hint
- Induces flowering in pineapple.
- Promotes fruit ripening.
- Promotes senescence and abscission.
- Used commercially as ethephon.
- Gibberellin
- Abscisic acid
- Cytokinin
- Ethylene
The Correct Option is D
Solution and Explanation
This question tests knowledge of plant hormones and their functions.
Step 2: Detailed Explanation:
Ethylene (D) is associated with the induction of flowering in pineapple.
In commercial pineapple cultivation, ethephon (an ethylene-releasing compound) is sprayed to induce flowering.
Ethylene promotes flowering in pineapple and other bromeliads.
Other hormones:
- Gibberellin (A): Promotes stem elongation.
- Abscisic acid (B): Promotes dormancy and stress tolerance.
- Cytokinin (C): Promotes cell division and shoot growth.
Thus, ethylene induces flowering in pineapple.
Step 3: Final Answer:
Thus, ethylene is associated with the induction of flowering in pineapple, which corresponds to option (D).
