玉米胚乳是碳、氮吸收的主要器官。胚乳中的淀粉和醇溶蛋白是影响籽粒产量和品质的主要储藏成分。这两种物质的合成需要营养组织提供蔗糖和氨基酸怍为主要的碳、氮基质。以前的研究指出,在不同玉米杂交种籽粒中,碳与氮的相对含量是有差异的(Canvin
Corn endosperm is carbon and nitrogen absorption of the main organs. Starch and gliadin in endosperm are the main storage components that affect grain yield and quality. The synthesis of these two substances requires that the vegetative tissue provide sucrose and amino acid 怍 as the major carbon and nitrogen substrates. Previous studies have shown that there is a difference in the relative amounts of carbon and nitrogen in different maize hybrids (Canvin
