Effects of Irradiation by Gamma Rays on Potatoes Tubers; ETUDE ANALYTIQUE DES TUBERCULES DE POMMES DE TERRE SOUMIS AUX RADIATIONS NUCLEAIRES
A study was made of the radiation effects of gamma doses between 100 and 50,000 rads on potato tubers. The results were evaluated with respect to preservation of the potato and possible modifications in the cellular structure and distribution of glucidic reserves. The results showed that doses lower than 1,000 rads had no inhibitory effects, but rather appeared to have a stimulating effect. Above 1,000 rads the germination is inhibited, and above 5,000 rads the tubers germinate in a very slow manner. The optimum dose to apply to tubers for preservation appears to be between 7,500 amd 8,000 rads. Tubers irradiated above 5,000 rads display significant morphological changes analogous to those observed when the young vegetables are seared by solar radiation. The study of the effects of radiation on the amino acids and vitamin C of potatoes shows that the amino acids are affected only to a slight degree which is of the same order as that found in cooking. The rate of destruction of vitamin C is proportional to the dose received. (J.S.R.)
