摘要: 采用室外实验和室内分析相结合的方法,分析乳苣(Mulgediumtararicum)全草氨基酸含量及粗蛋白含量,评价其营养及食用价值。结果表明:乳苣全草其幼苗期的粗蛋白含量最高,且大部分集中在叶片中,占整株的23.27%~55.60%;随着乳苣的逐渐生长,根、茎和叶的氨基酸含量呈降低趋势;乳苣根和茎的17种氨基酸呈显著的正相关关系。综合分析表明,乳苣含有丰富的氨基酸种类,是一种优质牧草。乳苣的地上部分(根和茎)氨基酸含量高于根,开花期干重最大,因此推荐乳苣开花期作为家畜的最佳使用阶段。分析不同生长阶段乳苣及其不同器官中氨基酸和粗蛋白含量,对评价乳苣在食用方面以及其他方面的应用具有重要意义及参考价值。

Abstract: Using a combination of outdoor experiments and indoor analysis, the nutritional value and edible value of Mulgediumtataricum was analyzed by analyzing the amino acid content and crude protein content. The results showed that the crude protein content of Mulgediumtataricum in the seedling stage was the highest, and most of crude protein was concentrated in the leaves, accounting for 23.27%-55.60% of the whole plant. With the gradual growth of Mulgediumtataricum, the amino acids content showed a decreasing trend in the roots, stems and leaves; there was a significant positive correlation in 17 amino acids between roots and stems of Mulgediumtataricum. Comprehensive analysis showed that Mulgediumtataricum was rich in amino acids and was a forage good quality. The above-ground part (root and stem) of Mulgediumtataricum had higher amino acid content than the root and had the highest dry weight during the flowering stage. Therefore, the flowering stage of Mulgediumtataricum was recommended as the best stage for domestic animals.It is of great significance and reference value to analyze the contents of amino acid and crude protein in different growth stages of Mulgediumtararicum and its different organs, so as to evaluate the application of it in food and other aspects.
