Abstract:

The three kinds of sugar content, including fructose, glucose and sucrose of the new sorghum No.3 and No.4 sweet sorghum stalk were determinated by HPLC under different storage conditions (defoliation stand, defoliation lie, leaf stand, leaf lie, pyramid type ) in 220 days. The results showed that the fructose content, glucose content and sucrose content showed decreasing tendency upon the whole storage method. The parameters tested of No.3 new sorghum were significantly higher than No.4 new sweet sorghum. As the storage time goes on, the content of three parameters above from highest to lowest is defoliation stand, defoliation lie, leaf stand, leaf lie, pyramid type 5th, pyramid type 4th, pyramid type 3rd, pyramid type 2nd ,pyramid type 1st in the whole storage period.
