The results showed that nitrogen supply obviously increased the contents of soluble sugar, sucrose and starch, and the activities of enzymes related to sucrose inversion and starch synthesis.
结果表明，施氮可明显促进籽粒可溶性总糖、蔗糖、淀粉含量的增加，促进蔗糖分解转化及淀粉合成关键酶活性的增强。
The soluble sugar is the direct resource of the synthesis of starch.
可溶性糖是淀粉合成的直接来源。
