Light-Induced Inhibition of Potato Tuber Sprouting.
In freshly harvested Alaska-grown potato tubers there is a"rest period" during which time no sprout growth can be visibly detected. This is followed by a physiological stage of development when sprout growth will occur in the dark but is suppressed by light. Following this is a stage of gradual resumption of growth of light-suppressed sprouts and a lessening of the inhibitory responses in tubers planted at successive lengthening periods of time after harvest.
