为了探究核桃不同品种之间的品质差异,对新疆地区29个核桃品种坚果的外观品质进行了调查评价,定性定量确定了其果仁中的含油量。综合评价了不同核桃品种的果实差异,以期为不断推广新疆优良核桃品种起到积极的作用。结果表明:核桃不同品种之间的坚果外观品质有差异,‘XJ-009’、‘XJ-017’、‘XJ-020’、‘XJ-021’、‘XJ-028’外观品质较优。核桃不同品种间的粗脂肪含量均较高且差异较大,粗脂肪含量均超过65%,符合国家Ⅰ级标准。其中‘XJ-023’粗脂肪含量最高,为78.4%。 In order to explore the quality differences among different varieties of walnut, the appearance quality of 29 walnut varieties in Xinjiang was investigated and evaluated, and the content of oil in nuts was qualitatively and quantitatively determined. Comprehensive evaluation of the different varieties of walnut fruit differences, with a view to continue to promote Xinjiang good walnut varieties play a positive role. The results showed that there were differences in the appearance quality of nuts between different varieties of walnut. The quality of ’XJ-009’, ’XJ-017’, ’XJ-020’, ’XJ-021’ and ’XJ-028’ was better. The content of crude fat in different varieties of walnuts is higher and different, the content of crude fat is more than 65%, which is in line with the national grade Ⅰ standard.
