Question

It takes a 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?

• A. Cytokinin and abscisic acid
• B. Auxin and ethylene
• C. Gibberellin and cytokinin
• D. Gibberellin and abscisic acid

Answer 1

The correct option is B Auxin and ethylene

Auxin promotes flowering in pineapple while ethylene is required to initiate flowering and for synchronising fruit-set in pineapples.

Thus, auxin and ethylene can be applied to artificially induce flowering in pineapple plants throughout the year to increase yield.
