世界能源危机和全球生态环境日益恶化迫使人们急需开发可再生能源。生物质能源作为一种清洁的可再生能源已受到世界各国的高度重视。发展生物质能源的瓶颈之一是生物质原料不足。甜高粱的生物学产量和含糖量极高, 同时兼有耐旱、耐涝、耐贫瘠和耐盐碱等诸多优良特性, 被认为是最具开发潜力的能源植物之一。该文从甜高粱的分类学、生物学特点、种质资源评价、功能基因以及基因组信息等方面综述了甜高粱的最新研究进展和存在的问题, 并展望了甜高粱作为能源植物的研发前景。
In light of the world’s energy crisis and the fast deterioration of the global environment, the development of renewable energy sources is urgently needed. The importance of biomass energy as a clean, renewable energy source has been recognized. Increasing a plant’s biomass is a bottleneck to overcome in developing bioenergy. Sweet is high in biomass production and sugar content, tolerates drought, water logging, low fertility, high salinity and alkalinity of the soil; And is regarded as an energy crop with great potential for improvement. This paper reviews the recent advances and problems in research into the taxonomy, biological characteristics, germplasm evaluation and genome information of sweet sorghum. It discusses the prospects of research and development of sweet sorghum as an energy crop.
