Current Question (ID: 12866)

Question:

Plant growth regulator, which promotes senescence and abscission of plant organs, is also related to which of the following physiological effects?

Options:

1. Thinning of cotton, cherry, and walnut
2. Overcome apical dominance
3. Early seed production in conifers
4. Formation of new leaves

Solution:

The plant growth regulator referred to in the question is ethylene, which is known to promote senescence and abscission of plant organs such as leaves, flowers, and fruits. Ethylene is also involved in the thinning of cotton, cherry, and walnut fruits, as it promotes the shedding of excess fruits to allow the remaining fruits to develop properly. Ethylene is not related to overcoming apical dominance, early seed production in conifers, or the formation of new leaves.
