Abstract:

In order to understand the methods and standards for determining the different maturity of apricot plum, the Flavor Queen fruit of apricot plum was used as the test material. Based on the different growth and development stages of the fruit and the changes in various indicators, different maturity classification standards and methods for Flavor Queen were constructed. After the 71st day after the blooming period of Flavor Queen, continuously pick and measure indicators such as firmness with peel, firmness without peel, and soluble solid content every 3 days until the fruit naturally fell off. The results showed that with the extension of the growth and development period, indicators such as firmness with peel, firmness without peel, and soluble solid content showed significant regular changes. After comprehensive analysis of various indicators, using firmness with peel, firmness without peel, and soluble solid content as variables and different growth and development days of Flavor Queen as observation variables, cluster analysis showed that the clustering results could be divided into 5 levels of maturity. Principal component analysis showed that there were significant differences in quality between different maturity levels, and discriminant analysis was used to validate the clustering results. The results showed that clustering analysis could be used to classify fruits with different harvest maturity levels. By screening the contribution rates of each indicator, it can be concluded that measuring indicators such as firmness with peel, firmness without peel, solid acid ratio, and soluble solid content can achieve the purpose of distinguishing different maturity grading standards and methods for Flavor Queen. Based on different production needs, theoretical basis can be provided to determine the maturity suitable for fresh food, processing, storage, transportation, and long-distance sales.
