It takes very long time for pineapple plants to produce flowers. Which combination of hormones can be applied to artificially induce flowering in pineapple plants throughout the year to increase yield? [NEET 2019]
✓ Correct answer: a) Auxin and Ethylene
ExplanationCorrect Answer: A Explanation: In pineapple, flowering can be artificially induced by the application of ethylene.Ethylene is known to promote flowering in some plants, including pineapple, and is commercially used to ensure uniform and year-round flowering, thereby increasing yield.Auxins, when applied along with ethylene (or ethylene-releasing compounds like ethephon), enhance the effectiveness of this treatment by supporting growth responses associated with flowering induction.Gibberellins generally delay flowering in many plants.Abscisic acid is a growth inhibitor and does not promote flowering.Cytokinins are mainly involved in cell division and delay of senescence.
