通过对平欧杂种榛、平榛、欧洲榛共43个品种的基本营养物质进行测定并分析差异性。结果表明：榛子水分含量3.87%～9.51%,淀粉含量0.92%～2.03%,总糖含量12.66%～19.09%,蛋白质含量29.22～68.57mg/g,脂肪含量53.80%～63.33%。不同榛子品系之间具有一定差异性,欧洲榛所有营养物质均与平榛和平欧杂种榛有显著差异,平榛与平欧杂种榛在淀粉与总糖含量上有显著差异。水分：平欧杂种榛〉平榛〉欧洲榛;淀粉：欧洲榛〉平欧杂种榛〉平榛;总糖：平欧杂种榛〉欧洲榛〉平榛;可溶性蛋白：欧洲榛〉平榛〉平欧杂种榛;脂肪：欧洲榛〉平欧杂种榛〉平榛。%The essential nutrients of 43 hazelnut varieties including Corylus heterophylla,Corylus avellanas and their hybrids were analyzed.Hazelnut kernel contained 3.87%-9.51% water,0.92%-2.03% starch,12.66%-19.09% sugars in total,29.22-68.57 mg/g protein,and 53.80%-63.33% fat content.All the nutrients of Corylus avellana are significantly different with those in Corylus heterophylla and hybrid hazelnuts.The contents of starch and total sugar in Corylus heterophylla and hybrid hazelnuts were significantly different.Three groups of hazelnuts were ranked in decreasing order of as follows： hybrid hazelnuts Corylus heterophylla Corylus avellanas by water content,Corylus avellanas hybrid hazelnuts Corylus heterophylla by starch content,hybrid hazelnuts Corylus avellanas Corylus heterophylla by total sugar content,Corylus avellanas Corylus heterophylla hybrid hazelnuts by soluble protein content,and Corylus avellanas hybrid hazelnuts Corylus heterophylla by fat content.
