Potato (Solanum tuberosum) cv. Atlantic and Superior were grown at alpine areas in Korea and stored at 5 and 15¡É. The effects of 3-chloro-isopropyl-N-phenyl carbamate (CIPC) and cloine salt of malefic hydrazide (CMH) on the sprouting rate, reducing sugar content, and chip color of potato tubers were determined during 6 months storage. Higher sprouting ratio was observed in potatoes stored at 15¡É than those at 5¡É. In particular, 1% CIPC treatment was effective in delaying and reducing sprouting. Potatoes stored at 5¡É for 180 days showed 1 % increase in reducing sugar content, resulting in dark colored chips. The chip color was found to be the best when potatoes were stored for 180 days at 15¡É. Atlantic, in general, was lower in reducing sugar contents compared with Superior, producing better colored chips. As far as chip color $quot;L$quot; value was concerned, no difference was detected between two cultivars treated with sprout suppressants.
