摘　　要：对微胚乳玉米双超1号在乳熟期(授粉后21 d)籽粒中的多种营养成分进行了测定,并与超甜玉米正甜68进行了比较。结果表明,双超1号的蛋白质、脂肪、总膳食纤维、β-谷甾醇、磷脂、总黄酮、镁、锌、钙、钠、钼、碘、泛酸、胆碱、VB2和氨基酸的含量高于正甜68;双超1号的总糖、淀粉、果酸、铁、锰、铜、钾、VE、VC、VB1和β-胡萝卜素的含量低于正甜68;粗纤维和硒的含量二者相同。表明微胚乳玉米是一种富含多种营养成分的鲜食玉米。The main nutritional components of the kernels were measured for the micro-endosperm maize Shuanchao1 in the milky maturity stage（21 days after pollination）,and compared with those of the super sweet maize Zhengtian 68.The results were as follows： the contents of protein,fat,total dietary fiber,β-sitosterol,phosphatide,total flavonoids,Mg,Zn,Ca,Na,Mo,I,pantothenate,choline,vitamin B2 and amino acid in Shuanchao1 were higher than those in Zhengtian68;the contents of sugar,starch,fruit acid,Fe,Mn,Cu,K,vitamin E,vitamin C,vitamin B1 and β-carotene in Shuanchao1 were lower than those in Zhengtian68;the contents of crude fiber and Se of the two maize materials were equal.These showed that the fresh ears of micro-endosperm maize are rich in nutrition.
