Sprouting Behaviour, Percentage Cpwl and Changes in Protein During the Storage of Potatoes at Different Temperatures

Storage behaviour of potatoes (S. tuberosum L. cv. ‘Kufri Chandramukhi’) was studied in relation to sprouting, per cent CPWL, protein changes and protease activity at different temperatures. Sprouting could be noticed after 6-day of storage at 10 ± 2°C and 32 ± 2°C while it was absent at 3°C. Number of sprouts per tuber increased thereafter and remained constant after 11 days. Sprout number also increased with the potato tuber size. Per cent CPWL values increased with the increase in weight categories, temperature and storage duration of potatoes. The amount of protein declined with the increased storage temperature while protease activity exhibited the reverse trend during the storage.
