【摘要】 [目的]探讨引入的10个不同种源地油莎豆种质资源的蛋白质氨基酸组成及其相互关系。[方法]引入不同种源地油莎豆种质资源，测定蛋白质、脂肪、粗纤维及氨基酸组成和含量情况，运用SPSS软件进行对比分析。[结果]不同种源地油莎豆种质资源之间蛋白质、脂肪、粗纤维含量和必需氨基酸含量差异均显著；不同种源地油莎豆种质资源氨基酸含量中，精氨酸的含量最高，甲硫氨酸含量最低；脯氨酸的变异系数最大，丙氨酸的变异系数最小；脯氨酸与其他15种氨基酸含量之间，甲硫氨酸与天冬氨酸、丝氨酸、组氨酸、赖氨酸、丙氨酸、精氨酸含量之间，赖氨酸与酪氨酸、缬氨酸含量之间的相关关系不明显；甲硫氨酸与苏氨酸、谷氨酸、缬氨酸、甘氨酸、亮氨酸、异亮氨酸、苯丙氨酸含量之间呈显著负相关关系；甲硫氨酸与酪氨酸含量之间呈极显著负相关关系；谷氨酸与精氨酸含量之间呈显著正相关关系；其余氨基酸含量之间均呈现极显著正相关关系。[结论]丝氨酸、甲硫氨酸和脯氨酸的含量可以综合反映油莎豆的氨基酸含量情况。更多还原

【Abstract】 [Objective]This study aims to make clear the composition & interrelation of protein and amino acid of 10 germplasm resources of Cyperus esculentus. [Method]10 germplasm resources of Cyperus esculentus were introduced, their compositions of protein, fat, coarse fiber and amino acid were measured. Comparison analysis was done using SPSS software. [Result]The compositions of protein, fat, coarse fiber and essential amino acid of the 10 germplasm resources of Cyperus esculentus are significantly different; in the amino acid of the 10 germplasm resources of Cyperus esculentus, the content of arginine is the highest and the content of methionine is the lowest. The variation coefficient of proline is the biggest and that of alanine is the smallest; there was no significant correlation between proline and other 15 amino acids, between methionine and aspartate, serine, histidine, lysine, alanine and arginine, and between lysine and tyrosine and valine. The contents of methionine were negatively correlated with threonine, glutamic acid, valine, glycine, leucine, isoleucine and phenylalanine. The contents of methionine and tyrosine were significantly negatively correlated. There was a significant positive correlation between glutamic acid and arginine content. The contents of other remaining amino acids showed a significant positive correlation. [Conclusion]The contents of serine, methionine and proline can comprehensively reflect the amino acid content of Cyperus esculentus.更多还原
