Title: Content of different forms of vitamin C in potatoes treated with ethylene chlorhydrin
Abstract: The levels of l-ascorbic acid, dehydroascorbic acid and of the bound form of vitamin C were investigated in the tissue from the vicinity of eyelets of dormant potatoes after treating the tubers with ethylene chlorhydrin. During the first week after exposure the l-ascorbic acid level does not change, significantly while the dehydroascorbic acid level decreases markedly. This decrease persists even during the following weeks and returns to normal only on the fourth week after treatment. The l-ascorbic acid level displays a decreasing tendency but a marked decrease may be observed only during the fourth experimental week. The level of the bound form of vitamin C does not change significantly for the whole duration of the experiment. It can be concluded on the basis of the results obtained that ethylene chlorhydrin deeply affects the oxidation-reduction systems of the potato cell, among other possibilities by disturbing the equilibrium of the important oxidation-reduction system formed by l-ascorbic and dehydroascorbic acid. The bound form of vitamin C does not appear to play a significant role in the process of sprouting.
