Abstract: The changes of the content of starch, soluble sugar and the activity of amylase were studied in two pumpkin varieties of ‘Ganli’,‘Huali during fruit growth and storage. The results showed that there were great differences in starch accumulation and final content between two pumpkin varieties. The content of starch, soluble sugar and the activity of amylase increased with fruit growth. At different storage temperature (6℃ and 25℃), the content of starch declined and the content of soluble sugar increased, and larger changes was observed at 25℃.

Key words: pumpkin, starch, soluble sugar, growth, storage
