Storage characteristics of Potato

There is an obvious physiological dormancy period after potato harvest. It usually lasts for 2 to 4 months, which varies from variety to breed. Generally speaking, the dormancy period of late-maturing varieties is short, while that of early-maturing varieties is long.

The length of dormancy period varies with maturity. The dormancy period of immature potato tubers harvested in the middle growth stage is longer than that of the same size but in the mature period. The storage temperature also affects the length of dormancy period, and the dormancy period of potato stored at suitable low temperature is long, especially the low temperature at the beginning of storage is very beneficial to prolong the dormancy period. It is generally believed that the appropriate storage temperature is 3-5 ℃, and the appropriate relative humidity for storage is 80%-85%. Too high humidity is easy to increase decay, while too low water loss increases and loss increases. Light can promote potato sprouting and increase the content of solanine glycosides in potato pieces. It is toxic to people and animals after eating, so measures should be taken to avoid light when storing potatoes.
