Identify the statement that is a characteristic of ethephon?
1 Readily absorbed
2 Transported within the plant
3 Releases ethylene slowly
4 All of them
Explanation:
The most widely used compound as source of ethylene is ethephon. Ethephon in an aqueous solution is readily absorbed and transported within the plant and releases ethylene slowly.

Statement A : Decrease in rate of respiration is called respiratory climactic. Statement B : Ethylene breaks seed and bud dormancy, initiates germination in peanut seeds, sprouting of potato tubers.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
The rise in rate of respiration is called respiratory climactic.

How many of the following are the effects influenced by ethylene?
1 1, 3, 5
2 1, 3
3 1, 2, 4
4 2, 3, 4
Explanation:
Ethylene is used to initiate flowering and for synchronising fruit-set in pineapples and also it promotes female flowers in cucumbers thereby increasing the yield. Auxin controls xylem differentiation and helps in cell division. Cytokinins help produce new leaves and chloroplasts in leaves. Gibberellins also promotes bolting (internode elongation just prior to flowering) in beet, cabbages and many plants with rosette habit.

Which of the following statement is correct regarding ethylene?
1 It delays senescence.
2 It decreases the respiration rate during fruit ripening.
3 It breaks seed and bud dormancy.
4 It inhibits flowering in mango.
Explanation:
Ethylene promotes senescence and abscission of plant organs especially of leaves and flowers. It enhances the respiration rate during fruit ripening. Ethylene is also used to initiate flowering and for synchronizing fruitset in pineapples. It also induces flowering in mango.
