Why is Suberization done?
The suberization of these cells inhibits the water loss from the tuber and inhibits fungal infection such as dry rot (Nolte et al., 1987). Under good conditions and at room temperatures, this process can take no more than a day but under cool temperatures such as 50 F, it can up to two weeks.
