An infra- red camera may help finding problem spots. Cure at 50 to 55°F for 2-3 weeks. Wound healing accelerates at higher temperature. The management in the first two weeks has important implica- tions for the rest of the storage season. Follow by ramping to holding tempera- ture (0.1 to 0.5°F/day). Hold at appro- priate temperature, and ventilation rate. Even distribution is of importance, because ventilation is the only tool available in case of disease problems. Dr. Olsen also covered the subject of tuber quality following cold injury. She emphasized the risk of harvesting out- side the ideal conditions. Such as frost, chilling injury, bruise, lack of wound healing, and problems with sugar and fry color. Freezing causes changes to membranes and water movement with- in tissue. The tubers become flaccid and water soaked. Ventilation is key. In the packing shed it is important to have quality control to determine whether potatoes can be shipped. Black spot bruise and shatter bruise are related to temperature and variety. One must always weigh the risk of warming up potatoes in relation to wound heal- ing, bruises and disease development. Weight loss is greater at 65°F than at 55°F. Wound healing was slower at 45°F and resulted in greater weight loss than at 55°F. Impact of cold injury on seed can be soft rot, dry rot, sprouting and plant performance. In fresh potatoes the visu- al aspects of the tuber such as bruise, sunken discoloration, overall quality also become important. There is a greater risk shipping frost damaged potatoes. In processing potatoes, the fry color is paramount. In trials fry color in Ranger Russet had been damaged for the rest of the storage season when temperatures had been down to 38°F and 45°F. Curing at 45°F causes unacceptable pro- cessing potatoes, too high in glucose. Earlier reconditioning causes less dark- ening than later reconditioning. “Temperature impact is real and doesn’t take much time,“ was Dr Olsen’s final comment.
