| 中文摘要: |
| 为探明新疆不同核桃资源的蛋白质与氨基酸含量之间的关系，采用凯氏定氮法和高效液相色谱法测定了26份新疆核桃种仁的蛋白质和氨基酸含量，采用相关性分析和通径分析方法分析了蛋白质与氨基酸的相关性。结果表明：26份新疆核桃种仁中以‘扎74’的蛋白质含量和总氨基酸含量最高，分别为19.70、16.92 g/100 g；相关性分析显示甘氨酸、精氨酸等13种氨基酸含量均与蛋白质含量呈极显著正相关，以甘氨酸相关系数最大，为0.906；通径分析结果显示天冬氨酸和谷氨酸对蛋白质含量的影响较大，通径系数分别为4.447和4.421。因此，在核桃育种中可通过采取提高天冬氨酸和谷氨酸含量的策略增加核桃蛋白质含量。 |
| 英文摘要: |
| In order to determine the relationship between protein content and amino acids contents of walnut resources in Xinjiang, the contents of protein and amino acid of 26 Xinjiang walnut kernels were determined by Kjeldahl method and high performance liquid chromatography, respectively, and correlation between protein and amino acid were analyzed by correlation analysis and path analysis. The results showed that the protein content and total amino acid content of ‘Zha 74’ in the 26 walnut kernels in Xinjiang were the highest, which were 19.70 g/100 g and 16.92 g/100 g respectively. Correlation analysis showed that the content of 13 kinds of amino acid components such as glycine and arginine were significantly and positively correlated with the protein content, in which the correlation coefficient of glycine was the largest, reaching 0.906. The results of path analysis showed that aspartic acid and glutamic acid had great influences on protein content, and the path coefficients were 4.447 and 4.421, respectively. So in walnut breeding, the protein content of walnuts could be increased by adopting strategies of increasing the contents of aspartic acid and glutamic acid. |
