Résumé

Weight loss was determined in tubers of 2 potato cultivars (Kufri Chandramukhi and Kufri Jyoti) grown at Modipuram and Shimla in Himachal Pradesh, India, and stored at 3 relative humidity levels of 30-35%, 60-65% and 90-95% with temperature maintained at 28-30 °C. In dormant tubers, the weight loss was higher at 30-35% RH. However, once the dormancy was broken and sprout growth started, higher RH level favoured greater sprout growth leading to higher weight loss. The weight loss was higher in tubers with uncured skin. Weight loss showed a non-significant relationship with number of sprouts per tuber, length of the longest sprout, surface area of tubers and periderm thickness.
