新疆引进美国扁桃品种种仁的品质特性

摘要

为了解新疆引进美国扁桃品种的品质特性,以本地品种纸皮为对照(CK),对Nonpareil、Sonora、Mission、Thompson、Ne puls ultra和Butte 6个美国扁桃品种种仁的7种常规成分、9种矿质元素、17种氨基酸和5种脂肪酸含量进行对比研究.结果表明,美国扁桃品种与本地扁桃品种都含有丰富的营养物质,测定的成分互有高低,脂肪、水解后还原糖、Na、P、Ca、亚油酸的含量美国品种间均值高于对照,而蛋白质、还原糖、Vc、K、Cu、Zn、油酸的含量美国品种间均值低于对照,灰分、干物质、氨基酸、Fe、Mg、Mn、棕榈酸等指标的含量两者相当.说明新疆喀什引进的美国扁桃品种保持了扁桃种仁营养丰富的品质特性,适应当地的气候条件.%In order to evaluate kernel quality of American-introduced almond varieties, seven ingredients and nine mineral elements and 17 amino acids and five fatty acids contents of almond kernel were determined in Nonpareil, Sonora, Mission, Thompson, Ne puls ultra, Butte, and the local almond variety Zhipi severed as a control. The result shows that the content of nine mineral elements were different between American and local almond varieties. The average content of fat, hydrolysis-reducing suga, Na, P, Ca and linoleic acid were higher than the control. But the average content of protein, reducing sugar, Vc, K, Cu, Zn and oleic acid were lower than the control. And the average content of ash, dry matter, amino acids, Fe, Mg and palmitic acid were equal to the control. Therefore, the almond varieties introduced from American to Xinjiang maintain the kernel characteristics.
