【 摘 要 】

In order to investigate the maximum storage period during their natural growth state, the sweet sorghum (Sorghum bicolor L. Moench) stems of four cultivars were analyzed to determine changes in contents of water, total sugars, main soluble sugars and the enzyme activity. From early November 2016 to late January 2017, the decrease in the total sugar content and the contents of sucrose, glucose and fructose slowed down, and the enzyme activities (sucrose synthase and sucrose phosphate synthase) involving sucrose metabolism in the stem remained stable. However, these indicators decreased significantly after the end of January 2017. Low temperatures and a dry environment were conducive to the storage of the sweet sorghum stems. During the winter (from early November 2016 to late January 2017) in northern China, the sweet sorghum plants can be stored naturally in the field via regulating sowing dates, which saves a lot of storage space and production costs for bioethanol company.
