对高油玉米和普通玉籽粒发育过程中还原糖、非还原糖和脂肪的积累动态及其相互转化关系进行了比较，结果表明，高油玉米与普通玉米籽粒发育过程中糖类、脂肪的积累动态基本相同，只是数量不同。脂肪数量的差异在籽粒发育的中后期达极显著水平。糖类与脂肪的积累呈明显负相关关系（r＝－0．7574）。
The dynamic changes of reducing sugars, non-reducing sugars and fat during the development of high-oil corn and common jasper were studied. The results showed that the accumulation of sugars and lipids during the development of high-oil corn and common corn Dynamic basically the same, but the number is different. The difference in the amount of fat in the mid-late grain development reached a very significant level. Sugar and fat accumulation showed a significant negative correlation (r = -0.7574).
