禾谷类作物的籽粒含有直链和支链两种不同结构的淀粉。两者比值是决定适口性的重要指标。高粱籽粒中直链和支链淀粉的比值是酒厂选料的指标之一。但是直链和支链淀粉的常规分析方法较为繁琐,对于育种工作者来说,无法在大量低世代材料中进行上
Grains of cereals contain two different linear and branched starches. The ratio between the two is an important indicator of palatability. Sorghum grain ratio of linear and amylopectin is one of the indicators of winery selection. However, conventional analytical methods for linear and amylopectin are cumbersome and can not be performed on a large number of low-generation materials by breeders
