Regulation and control of potato tuber dormancy and sprouting
Potato crop is one of the most important vegetable crops. Potato tubers are the economic part used in human nutrition and at the same time the part used for multiplying. Tubers enter obligatory dormancy when they mature. The dormancy of tubers comprises a wide range of physiological and biochemical processes. The status and duration of dormancy depend on the genetic background, tuber's development stage, environmental conditions and operations during tuber's growth and storage. Abscisic acid and ethylene maintain the dormancy of the tuber.
