Potato bruising and management
Bruises develop due to impacts that either break the cells apart (shatter bruise) or rupture the cell membranes (blackspot). Shatter bruises appear as cracks on the tuber skin, which can extend into the core of the tuber, making it an easy entry point for fungi and bacteria.
The risk of bruises can be reduced. Factors influencing potato bruising and how to manage them are included in this PotatoLink factsheet.
