【摘要】 为探究新疆不同核桃品种的品质差异,合理利用新疆核桃资源,本研究对新疆11个核桃品种的营养品质(包括脂肪、碘价、脂肪酸、维生素E、还原糖、纤维素、总糖、单宁和蛋白质各组分)和外观品质(包括果形指数、单果重、壳厚度、出仁率)进行测定,利用方差分析法对各核桃品种的品质进行比较。结果表明不同核桃品种间品质存在差异,从营养品质来看,可以从中筛选出3个高脂肪品种即纸皮、浑巴士和新巨丰,1个高维生素E含量品种即新温81号,2个高蛋白品种即新温81号和新萃丰;纸皮、温138号外观品质较优,出仁率较高的品种有新温81号、温138号、新179号和纸皮。综合各品质,筛选出品质较好的品种有纸皮、扎71号和新温81号。更多还原

【Abstract】 In order to explore the quality difference of different walnut varieties in Xinjiang and make rational use of walnut resources in Xinjiang, the nutritional quality(including fat, iodine value, fatty acid, vitamin E, reducing sugar, cellulose, total sugar, tannin and protein components) and appearance quality(including fruit shape index, protein content) of 11 varieties of walnut in Xinjiang were studied. Fruit weight, shell thickness and kernel yield were measured. In this regard, variance analysis was adopted to make comparison over the quality of different walnut varieties. The results showed that the quality varies according to walnut varieties. Three varieties with high content of vitamin E, such as Xinwen 81, Xinwen 81 and Xincuifeng, were selected from the three varieties with high fat content, such as Zhipi, Hunbashi and Xinjufeng. The results showed that there were three varieties had high content of vitamin E, such as Xinwen 81 and Xincuifeng. Besides, the appearance quality of Zhipi and Wen 138 was better, and the walnut varieties with higher kernel rate were Xinwen 81, Wen 138, Xin 179 and Zhipi. Finally, according to the comprehensive quality, the varieties with better quality were selected, such as Zhipi, Zha 71 and Xinwen 81.更多还原
