Sprouting of potato tubers is initiated by which of the following PGR?
1 Cytokinin
2 Ethylene
3 Both (1) and (2)
4 None of these
Explanation:
Ethylene breaks seed and bud dormancy, initiates germination in peanut seeds, sprouting of potato tubers.

Statement A : Ethylene helps leaves/ upper parts of the shoot to remain above water. Statement B : Ethylene promotes root growth and root hair formation.
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.

Ethephon hastens fruit ripening in
1 Cherry
2 Tomato
3 Apple
4 2 and 3
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. Ethephon hastens fruit ripening in tomatoes and apples and accelerates abscission in flowers and fruits (thinning of cotton, cherry, walnut).
