Explanation:
Inducing Flowering in Pineapple Plants
- Pineapple plants naturally take a long time to produce flowers, which can limit the yield of the crop.
- To artificially induce flowering in pineapple plants throughout the year and increase yield, a combination of hormones is required.
Combination of Auxin and Ethylene
- Auxin and Ethylene are the hormones that can be applied to artificially induce flowering in pineapple plants.
- Auxin helps in the initiation of flowers, while Ethylene promotes the flowering process.
- By applying a combination of Auxin and Ethylene, the flowering process can be accelerated, leading to increased yield of pineapples throughout the year.
Other Options
- Cytokinin and Abscisic acid: Cytokinin promotes cell division and growth, while Abscisic acid is involved in stress responses. This combination is not ideal for inducing flowering in pineapple plants.
- Gibberellin and Cytokinin: Gibberellin promotes stem elongation and flowering, while Cytokinin promotes cell division. This combination may not be as effective in inducing flowering in pineapple plants compared to Auxin and Ethylene.
- Gibberellin and Abscisic acid: Gibberellin promotes flowering, while Abscisic acid is involved in stress responses. This combination may not be as effective in inducing flowering in pineapple plants as Auxin and Ethylene.
Therefore, the correct combination of hormones to artificially induce flowering in pineapple plants throughout the year and increase yield is Auxin and Ethylene.
