[#341] Dormancy in potato can be break by use of
Correct Answer
(D) All of these
Explanation
Solution: Dormancy in potatoes can be broken by the use of Thiourea, Ethylene chlorohydrin and Potassium thiocyanate . Potato tuber dormancy is defined as an inability to sprout under conditions that are favorable for sprouting. Thiourea - soaking the potato tuber in 1%, aqueous solution for 85 hour is suggested to break the tubers' dormancy. Ethylene chlorohydrin is highly volatile and the gas aids in breaking dormancy. Remove the tubers, air-dry, and hold at 18 - 25°C. Potassium thiocyanate solutions gave excellent results in forcing early sprouting. The rest period of cut sets was materially shortened when the tubers were soaked in 3- or 2-percent solutions of potassium thiocyanate.
