甜高粱抗倒伏性研究进展

摘要

甜高粱生物产量高,含糖量高,乙醇转化率高,抗逆性强,是能源作物.倒伏一直是影响甜高粱高产稳产的主要因素,倒伏导致甜高粱籽粒产量下降并影响茎秆干物质的积累,也不利于收割.从形态和生理生化性状、预防的栽培措施、遗传、评估等方面对甜高粱抗倒伏性的研究进行了探讨,以期为甜高粱的推广种植和品种选育提供参考.%As an energy crop, sweet sorghum has the characteristics of high yield, high sugar content, high alcohol inversion rate and stronger capacity in stress resistance. Lodging has long been recognized as a severe malady of sweet sorghum. Apart from the difficulties imposed on harvesting, lodging might reduce grain yields and dry matter accumulation of stalk. The progress made in lodging resistance related research in sweet sorghum on morphological and physiological characters, cultivation, genetic mechanism, and evaluation were summarized, and the breeding point was analyzed.
