摘　　要：为研究不同品种山楂果实的贮藏性能,以‘大金星’、‘泽州红’和‘红五棱’为试样,通过质构剖面分析(TPA)和穿刺试验,探讨不同品种山楂果实贮藏期果实质地的差异、变化规律和贮藏性能。结果表明,不同品种山楂果实质地之间存在一定差异,贮藏性也具有差异。在贮藏期间‘,大金星’的果皮硬度、果肉硬度和粘附性变化值最小‘,红五棱’次之‘,泽州红’各指标的变化值最大。主成分分析的综合得分显示,山楂贮藏性能由好到坏依次为‘大金星’>‘红五棱’>‘泽州红’。To investigate the storage performance of different varieties of hawthorn fruits,‘Dajinxing’,‘Zezhouhong’and‘Hongwuleng’were used as specimens to carry out texture profile analysis(TPA)and puncture test.The differences of fruit texture,texture change patterns and storage performance of different varieties of hawthorn fruits during storage were investigated.The results showed that there were some differences in texture and storage properties among different varieties of hawthorn fruits.During the storage period,‘Dajinxing’had the smallest values of variation in peel hardness,flesh hardness and adhesion,followed by‘Hongwuleng’,and‘Zezhouhong’had the largest value of variation in each index.The overall scores of the principal component analysis showed that the storage performance of hawthorn was‘Dajinxing’>‘Hongwuleng’>‘Zezhouhong’in the order of good to bad.
