番茄质地构成与贮藏期间主要性状的相关分析

Performance and Correlation Analysis of Main Characters of Tomato Fruit Before and After Storage

以9个番茄品种为材料,测定采后果实质地参数及贮藏期间主要性状变化,分析其质地参数与贮藏期间主要性状之间的相关性。结果表明:硬度与可溶性固形物极显著负相关,与腐烂率显著负相关;凝聚性与胶性、咀嚼性极显著正相关,与粘弹性显著正相关;粘弹性与咀嚼性极显著正相关,与呼吸强度极显著负相关;胶性与咀嚼性极显著正相关,与腐烂率显著负相关。质构仪测定的硬度及胶性可以作为耐贮藏性的重要指标。

Taking nine tomato strains as material,the interrelation of physical properties and main characters during storage of tomato were studied.The results showed that the hardness was extremely significantly negative correlation with the content of soluble solid and significantly negative correlation with the decay rate;the cohesiveness was extremely significantly positive correlation with the gumminess and the chewiness,and significantly positive correlation with the springiness of fruit;the springiness was extremely significantly positive correlation with the chewiness,and extremely significantly negative correlation with the respiration;the gumminess was extremely significantly positive correlation with the chewiness,and significantly negative correlation with the decay rate.The hardness and the gumminess measured using Texture Analyzer could be used as an important indicator of resistance to storage.
