NEETBotanyPlant - Growth and Development
What effect does ethylene have on deep water rice plants?
Options
- AReduces internode elongation
- BPromotes rapid internode/petiole elongation
- CInhibits leaf growth
- DDecreases root growth
Correct answer
B. Promotes rapid internode/petiole elongation
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.
