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 through the year to increase yield?
|
|
Gibberellin and Abscisic acid
|
|
|
Cytokinin and Abscisic acid
|
|
|
Auxin and Ethylene
|
|

Gibberellin and Cytokinin

Explanation:
Detailed explanation-1: -Auxin is required for flowering in pineapple while ethylene is required to initiate flowering and for production of synchronised fruit set in pineapple. Thus, auxin and ethylene can be applied to artificially induce flowering in pineapple plants throughout the year to increase yield.
Detailed explanation-2: -Gibberellin is the hormone that is majorly found in plants and they help in the blooming of long-day plants.
Detailed explanation-3: -Within I day after pineapple plants are treated with naphthalene acetic acid they begin producing ethylene. It is suggested that applied auxins mimic the action of ethylene by stimulating ethylene formation, and that ethylene, not auxin, causes pineapples to flower.
