| 摘 要： | 【目的】对影响葡萄品质的理化指标进行简化,提高葡萄品质的检测效率。【方法】通过主成分分析、相关性分析、聚类分析的数学方法对所测得的105个葡萄品种的10个理化指标进行简化,从而简化影响葡萄品质的理化指标。【结果】将反映葡萄品质的10个理化指标简化为5个指标,分别为可溶性固形物、固酸比、总酸、果胶和纤维素,经初步分析,这5个指标能够代表葡萄的甜度、酸度、酸甜度、涩味和果实硬度。【结论】可溶性固形物、固酸比、总酸、果胶和纤维素这5个指标基本可反映葡萄的品质。

| Abstract: | Objective]The purpose of this project was to simplify the physicochemical indexes for the quality of grape,thus improving the testing efficiency of grape quality.Method]Ten physicochemical indexes of 105 varieties were simplified among the principal components analysis,correlation analysis and cluster analysis.Result]The results showed that the ten tested indexes were finally simplified into 5 indexes,which were soluble solid content,ratio soluble solid to acid,total acidity content,pectin,and cellulose.... |
