The endosperm sugars of a new corn (Zea mays L.) mutant, sugary enhancer (se), were analyzed by gas-liquid chromatography and were compared with sugars of other genotypes. Illinois 677a, a sugary (su) inbred containing the se gene, was high in sucrose and was distinguished from all of the other genotypes by its high maltose content. During kernel development, the maltose content of IL677a increased to 3.28% dry weight at 40 days postpollination and remained high at the dry mature stage, whereas ;Silver Queen,' a high quality sugary (su) hybrid not possessing the se gene, showed no such trend in maltose accumulation. Sucrose, fructose, and glucose decreased during kernel development in ;Silver Queen' and IL677a from 19 days postpollination until the dry mature stage. The slow drying characteristic and the reduced starch content previously reported for maturing seeds of IL677a may be related to the maltose accumulation reported here.
利用气液色谱法分析了一种新的玉米（Zea mays L.）突变体——含糖增强子（se）的胚乳糖分，并与其他基因型的糖分进行了比较。伊利诺伊677a是一个含有se基因的含糖（su）自交系，蔗糖含量高，且以其高麦芽糖含量与所有其他基因型区分开来。在籽粒发育过程中，授粉后40天时，IL677a的麦芽糖含量增加至干重的3.28%，在干熟期仍保持较高水平，而不具有se基因的优质含糖（su）杂交种“银皇后”在麦芽糖积累方面没有这种趋势。在“银皇后”和IL677a中，从授粉后19天到干熟期，籽粒发育过程中蔗糖、果糖和葡萄糖含量均下降。先前报道的IL677a成熟种子的缓慢干燥特性和降低的淀粉含量可能与此处报道的麦芽糖积累有关。
