Abstract This study was performed to investigate the effect of different storage temperatures (25 ℃, 4 ℃) on carbohydrate content and respiratory metabolism in outer or inner scales of oriental lilies hybrid ‘Siberia’. Results indicated that starch contents started to decrease gradually when the lily bulbs were stored at 25 ℃ or 4 ℃. It was found the total soluble sugar content of scales was higher in the middle stage of cold treatment than early or later stages. In addition, a more significant decrease during later stage was observed in outer scales than inner scales. Bulbs sweetening were especially apparent under 4 ℃ treatment. During cold treatment of lily bulbs, key enzymes of three respiratory pathways－ATP of glycolytic pathway (EMP), SDH of tricarboxylic acid (TCA) and G6PDH pentose phosphate (PPP)－showed different changes: During first 30 days, three respiratory pathways all changed sharply, EMP increased, TCA and PPP decreased, outer scales changed more sharply than inner scales. After 30 days, EMP began to decrease, while TCA and PPP increased. Respiratory metabolism was according with dormancy process.
