不同类型梨果肉质地发育动态比较分析
Comparative analysis of dynamic development of flesh texture in different types of pear fruits
摘要
Abstract
[Objective]The purpose of this study was to explore changes in the flesh texture of different types of pear varieties at different growth and development stages,and provide a reference for optimizing pear texture evaluation methods.[Methods]The study employed the puncture method and texture polyhedral analysis(TPA)with a physical property analyzer,using crispy and soft pear varieties as experimental material.Relevant fruit indicators were measured and analyzed.[Results]As pear fruits grew,single fruit weight and soluble solid content showed an increasing trend.Texture parameter measured through the puncture and TPA methods,including puncture fruit firmness,puncture flesh firmness,puncture flesh stiffness,TPA flesh firmness,fracture,cohesiveness,springiness,adhesiveness,and chewiness,generally showed a decreasing trend.The rate of decline varied among pear varieties and texture parameter,particularly during days after flower bloom(97～153 d).Soft-flesh pears exhibited higher TPA flesh firmness,fracture,springiness,adhesiveness,chewiness,punctured fruit firmness,punc-tured flesh firmness,and punctured flesh stiffness compared to crispy-flesh pears,whereas crispy flesh pears demonstrated great-er adhesiveness.Single fruit weight and soluble solid content were significantly negatively correlated with TPA flesh firmness,fracture,cohesiveness,springiness,gumming,chewiness,punctured fruit firmness,punctured flesh firmness,and punctured flesh stiffness,but positively correlated with adhesiveness,though the latter correlation was not significant.PCA analysis of tex-ture parameters showed that the first principal component accounted for 64.3%of the variance,and the second accounted for 23.8%.The comprehensive PCA scores for soft flesh pear were higher than those for crispy flesh pear fruits,clearly distin-guishing the two types.[Conclusion]The study elucidated the dynamic changes in texture between soft flesh and crispy flesh pears,and highlighted significant differences in their characteristics.An indicator model could be established to quantitatively evaluate fruit flesh quality and maturity based on mature fruit texture parameters.关键词
