Regulation of Potato Tuber Dormancy | Asian Journal of Research and Review in Agriculture

Potato tuber dormancy is the final stage of tuber development, which aids in the preservation of tubers as vegetative reproduction organs in less-than-ideal growing conditions. Potato tubers (Solanum tuberosum L.) are dormant, meaning they will not sprout. The dormancy of the tuber is broken and sprout growth begins when the time of postharvest storage is extended. Several biochemical changes accompany the breaking of dormancy and the commencement of sprout growth in potato tubers, the majority of which are crucial to the nutritional and processing properties of potatoes. Tuber dormancy regulation is thought to be influenced by environmental, physiological, and hormonal regulatory systems. The environmental and endogenous elements that cause tuberization have been reviewed and discussed in this paper. In addition, several biochemical and physiological processes that lead to greater tuberization under the influence of environmental and endogenous variables are thoroughly described.
