中文摘要：为了解绍兴香榧品质情况,提高香榧品质及商品价值,对来自绍兴香榧核心产区12个香榧样品的21个外在和内在指标变异情况进行研究,并对其变异情况及坚果综合品质进行了主成分分析和聚类分析。结果表明:香榧外观及内在品质各指标差异显著。香榧样品种仁平均油脂质量分数为50.28%,蛋白质平均含量为12.70 g/100 g,而且不同产区之间差异皆显著(P<0.05);香榧种仁不饱和脂肪酸所占比例在60.08%~75.77%,主要为油酸和亚油酸。经综合评价及聚类分析可知,嵊州的香榧综合评价值最高,其次依次为诸暨的香榧和绍兴稽东的香榧。种子长度、油脂质量分数、种子质量、蛋白质含量、油酸和亚油酸质量分数是评价香榧品质质量的重要指标。综合评价分析表明坚果品质综合表现较优的为嵊州香榧。综上,利用主成分分析和聚类分析可以对香榧坚果品质进行评价和其简化。

外文摘要：The objective of this investigation was to explore the nutritional quality of Torreya grandis ‘Merrilli＇ nuts. Variations in 21 internal and external quality attributes of 12 nut samples from the core growing area of Shaoxing, Zhejiang province were measured and analyzed by principal component analysis（PCA） and cluster analysis（CA）. Furthermore, a comprehensive evaluation was carried out on the quality of T. grandis ‘Merrilli＇ nuts. The results showed that significant differences in both internal and external quality characteristics were observed among 12 samples. The oil and protein contents of T. grandis ‘Merrilli＇ nut kernels significantly varied among geographical areas（P 0.05）, with average values of 50.28% and 12.70 g/100 g, respectively. The proportion of unsaturated fatty acids in the kernel oil was in the range of 60.08%–75.77%, oleic acid and linoleic acid being the predominant ones. Comprehensive evaluation and PCA analysis demonstrated that the comprehensive score of T. grandis ‘Merrilli＇ from Shengzhou was the highest, followed by those from Zhuji and Shaoxing＇s Jidong. The seed length, total fat content, seed weight, and average protein content, oleic acid and linoleic acid were considered as the most important quality indicators. In summary, PCA and CA could simplify the evaluation of T. grandis ‘Merrilli＇ quality.
