Chilling Injury
General partnerCrop protection for the potato industry

Potatoes are sensitive not only to freezing but also to chilling. Chilling injury occurs if tubers are exposed to temperatures between 0° and 3°C. Chilled tissue will
discolour, turning grey or black, even though ice crystals have not formed. If the tissue turns reddish-brown after chilling, the injury is called mahogany browning.
