摘 要 ：采用SDS-PAGE电泳和切胶比色进行亚基定量的方法，研究施氮量对2个小麦品种胚乳部分HMW-GS和GMP积累的影响。结果表明，高蛋白小麦品种徐州26在花后14 d HMW-GS就开始形成，低蛋白品种宁麦9号在花后21 d才开始形成。增施氮肥对小麦灌浆前期HMW-GS的形成作用不明显，而有利于徐州26 HMW-GS积累速度的提高和HMW-GS快速积累期的
Abstract:Accumulations of high molecular weight glutenin subunits (HMW-GS) and glutenin macropolymer (GMP) play key roles in grain quality of wheat (Triticum aestivum L.). The aims of this study were to analysis dynamic changes in contents of each high molecular weight glutenin subunit and GMP, and
