| 摘 要： | 通过田间试验和室内分析，研究不同面包小麦品种的产量及其蛋白质含量对氮肥用量的反应。结果表明，４个品种的产量，需肥量和籽粒蛋白质含量都有显著差异。应用 ＳＤＳ－ＰＡＧＦＥ法结合薄层扫描，得出安农９１９２和安农０１１６８的ＨＭＷ－ＧＳ组成为１，５＋１０，７＋８，山东１８７为１，１３＋１６，５＋１０，豫麦２８号为１，７＋９，５＋１０。根据多项式回归，４个品种的最高产量位点依次为８１０６．０，７２５５．５

| Abstract: | Field experiment and chemical analyses were conducted to study the response
of grain yield and protein content of wheat cultivars to nitrogen supply level. These four cultivars
tested differed greatly in yield, nitrogen requirement and grain protein content. Results obtained
by SDS-PAGE and thin layer scanning showed that the composition of the subunits of glutenin in
grains of these four bread wheat cultivars were different ,Annong 9192 and 91168 belong to 1, 7
8, 5 10; Shandong 187 to 1, 13 16, 5 10 and Yumai 28 to 1,7 9, 5 10. Based on
multinomial regression analysis the maxium yield and nitrogen applied rate of four cultivars were
8106. 0, 7255. 5, 7159. 5, 6000. 0 kg/ha and 337. 5, 301. 5, 247. 5, 321. 0 kg/ha, respectively
and protein contents were 16.0%, 13.2%, 11.1% and 17.5% at the maxium yield. Define
dY/dN as formation rate of grain yield and dP/dN as biosynthesis intensity of protein in these
four cultivars were also quite different. |
