| 目的 为了解不同品种杏果实在贮藏期间的耐贮性，筛选最适贮藏的杏果实品种。方法 以新疆主栽的14个杏果实品种为试材，测定贮藏期间果实硬度、可溶性固形物、可滴定酸、Vc含量、呼吸强度、果实相对电导率、总酚、类黄酮、叶绿素和腐烂率10个指标。结果 在贮藏末期，“小红杏”的L*值、a*值、b*值、总酚、类黄酮、硬度、SSC、Vc含量、相对电导率、腐烂率均与初始值相比差异显著;“和田明星杏”的L*值、a*值、b*值、总酚、类黄酮、硬度、SSC、TA均与初始值相比变化较小。“小红杏”的呼吸峰值比其余峰值高15.07%~37.17%，而“和田明星杏”的峰值比其余峰值低22.62%~40.42%，低于其他峰值。库车小白杏叶绿素下降最慢，伊利吊干杏下降最快。贮藏期间各指标均呈现不同程度的相关性，各指标间存在信息重叠。主成分分析提取出4个主成分，方差贡献率累计达到78.936%，可代表原始指标的大部分信息。结论 综合各项指标可得，“和田明星杏”的贮藏性优于其他品种。文中研究可为新疆杏果实的栽培提供理论依据。 |

| The work aims to understand the storage tolerance of different varieties of apricot fruits during storage and screen out the the optimal varieties of apricot suitable for storage. With 14 apricot cultivars mainly planted in Xinjiang as test materials, 10 indexes of fruit hardness, soluble solids, titratable acid, Vc content, respiration intensity, relative conductivity, total phenols, flavonoids, chlorophyll and decay rate were determined during storage. At the end of storage, the L value, a value, b value, total phenol, flavonoid, hardness, SSC, Vc content, relative conductivity and decay rate of Xiaohong Apricot were significantly different from the initial values, and the L value, a value, b value, total phenols, flavonoid, hardness, SSC and TA of Hetian Mingxing Apricot all changed little compared with the initial values. The respiration peak of Xiaohong Apricot" was 15.07%-37.17% higher than that of other peaks, while the respiration peak of Hetian Mingxing Apricot was 22.62%-40.42% lower than that of other peaks. The chlorophyll of Kuqa Xiaobai Apricot decreased the slowest, and that of Yili Diaogan Apricot decreased the fastest. During storage, each index showed different degrees of correlation, and there was information overlap between each index. Four principal components were extracted by principal component analysis, and the variance contribution rate reached 78.936%, which could represent most of the information of the original index. According to the comprehensive indexes, the storage adaptability of Hetian Mingxing Apricot is better than that of other varieties, which can provide a theoretical basis for the cultivation of apricot fruit in Xinjiang. |
