What is the primary use of ethylene in pineapples?
Options
- APromoting root growth
- BInitiating flowering and synchronising fruit-set
- CEnhancing seed germination
- DIncreasing leaf size
Correct answer
B. Initiating flowering and synchronising fruit-set
Step-by-step solution
Ethylene promotes rapid internode/petiole elongation in deep water rice plants. It helps leaves/ upper parts of the shoot to remain above water. Ethylene is used to initiate flowering and for synchronising fruit-set in pineapples. Ethylene is highly effective in fruit ripening. It enhances the respiration rate during ripening of the fruits.
