A review of the scientific literature relating to the physiology of po
tato (Solanum tuberosum) tuber dormancy is presented. Effort has been
concentrated on an up-to-date overview of the current state of underst
anding, rather than comprehensively covering the very extensive litera
ture going back over many decades. The format chosen follows the fate
of the crop. After defining tuberisation and dormancy, the physiologic
al activity of the dormant tuber is reviewed and the storage environme
nt is considered from both a physical and chemical standpoint. Advance
s in chemical control and the potential for molecular biology are high
lighted.
