能源作物甜高粱抗逆性的研究进展

Research advances of stress tolerance in sweet sorghum

甜高粱具有抗旱、耐涝、耐盐碱等优良特性,对不同类型土壤都有很强的适应能力,是中国重要的粮食作物、糖料作物和能源作物之一。在石油资源面临枯竭的严峻形势下,甜高粱作为能源作物已受到全世界的广泛重视。本文就国内外对甜高粱在盐碱、干旱、温度、及重金属胁迫等多种逆境条件下,其生理生化及分子层面变化的研究做了概述,为今后大力开发利用甜高粱并为将其在江苏沿海滩涂地区引种培育提供理论依据。

Sweet sorghum, which belongs to one of the important food crops and sugar crops as well as energy crops, is adaptive to different types of soil under drought, water logging, salinity stresses. Sweet sorghum as an energy crop has received widespread attention around the world in the depletion of oil resources under the grim situation. In this paper, physiological/biochemical and molecular level changes in sweet sorghum in response to salinity, drought, temperature, and heavy metal stresses were summarized, which will lay a theoretical basis for vigorous development and future utilization of sweet sorghum, and fosters the introduction of sweet sorghum into Jiangsu coastal beach areas.
