Gamma irradiation influence on storage and quality of potatoes (in Bulgarian)

OSTI ID:4310623
Gamma irradiation of three varieties potatoes, early crop, middle-early crop, and late crop, was studied. Tubers were irradiated in the autumn with 8 and 10 kR. Weight losses, starch contents, and culinary alterations were investigated. Irradiated tubers in all three varieties of potatoes did not sprout. At the end of April, weight losses of non-irradiated potatoes were 9 to 14.5%, and of irradiated, 0.5 to 4.5%. After one year of storage these losses were respectively 44 to 56% and 11 to 19%, in relation to the variety and the radiation dose. Tubers infected with Spondylocladium atrovirens Harz were not appropriate for prolonged storage. In the spring substantial differences were not established in the quality of controls and irradiated tubers. After one year storage of irradiated tubers proved to be with lower quality characteristics in comparisons to new crop, but were nevertheless suitable for consumption. (auth)
