In healthy potato tubers and in mixtures containing 20 and 50% tubers infected with late blight, respiration intensity during storage was up to 5 times greater in mixtures containing 50% diseased tubers than in healthy ones. When stored at 4 deg C, respiration intensity in healthy tubers was lower in those previously stored at 13 deg for 18 days than in those stored at 4 deg for the whole time. Respiration intensity in healthy tubers was lowest in storage at the lowest atmospheric m.c., but was highest where healthy and diseased tubers were stored together under these conditions.
