饲用高粱的价值不仅在于茎叶中含有单宁(Перуанский等,1989),而且还在于含糖。后者是由遗传决定的(Семенова,1988)。糖含量的提高有助于青饲料的品质。在意大利、西班牙、法国等国家,从高含糖量的高粱品种中提取的糖用于食用和制造酒精(Subramanian等,1987)。然而高粱基因型的饲料价值不仅在于茎汁液中糖含量,还在于蛋白质(氮化物)含量, The value of fodder sorghum is not only the tannin contained in the stems and leaves (Перуанский et al., 1989), but also sugars. The latter is genetically determined (Семенова, 1988). The increase in sugar content contributes to the quality of the green feed. In countries such as Italy, Spain, France, sugars extracted from high-sorghum sorghum varieties are used for consumption and for the manufacture of alcohol (Subramanian et al., 1987). However, the sorghum genotype feed value lies not only in the sugar content in the stem juice but also in the protein (nitride) content,
