Abstract: Changes of starch content, soluble sugar content and amylase activity in different parts of bulb in Lilium davidii var. unicolor and CV. Elite in Asia lily were studied during bulb development. The results indicated that mother bulb was the metabolism source during geminating stage, especially the exterior scales was the most important part. It was the marker of daughter bulb development that starch content and soluble content increased together. Sucrose was the basic form of soluble sugar in lily bulb. Changes of reducing sugar indicated the supply and transform of carbohydrate. Amylase acts an important role in adjusting and balancing the form of carbohydrate during the bulb development.

Key words: lily, bulb, development, carbohydrate, amylase
