摘　　要：甜高粱茎秆多汁,糖分含量高,是最具有发展前景的绿色能源作物之一。作为重要的生物质能源作物,种植甜高粱的直接目标是获得高的糖产量。因此,了解甜高粱茎秆糖的产量形成过程及其调控途径对于甜高粱品种改良与高产栽培具有重要意义。综述了甜高粱茎秆糖产量形成过程中糖分组成、分布、积累规律及其调控途径(主要包括播期、矿质营养、栽培方式和密度、源库改变4个方面)的研究进展,分析了茎秆糖分研究中存在的问题,并就未来研究重点进行了展望。Sweet sorghum （Sorghum biocolor L. Moench） is one of the leading candidates for cleaner energy crops, characterized by abundant juice and high sugar content in its stalk. As a renewable bioenergy crop, the goal of planting sweet sorghum is to obtain high sugar yield. Therefore, it is necessary for improving sweet sorghum cuhivars and cultivation practices to understand sugar yield formation and regulation. In the present paper, we summarized the progress made in research on the sugar components, distribution, accumulation and regulation including sowing time, mineral nutrition, cultivation and planting density, source sink alteration in stem of sweet sorghum, analyzed the existing problems and viewd the research focuses in the future..
