摘要
在不同种植密度下,研究了烯效唑(S-3307)干拌种浓度对冬小麦生育后期叶、茎和穗中氮含量及籽粒品质的影响。结果表明,烯效唑提高了小麦生育后期叶、茎和穗中的含氮量,且对主茎的影响大于分蘖,随其拌种浓度的增加,冬小麦籽粒蛋白质含量加大。烯效唑改善了籽粒中蛋白质的组分,对清蛋白、球蛋白的含量及其和均以20 mg/kg拌种处理效果最好;随其拌种浓度的升高,对醇溶蛋白和麦谷蛋白含量及其和的影响越明显。烯效唑通过对氮源的调控而对蛋白质进行了调控。
The experiment was conducted with seed dressing of uniconazole （S-3307） with different concentrations （0, 10, 20 and 40 mg/kg） and different planting densities（90 × 10^4 , 180 × 10^4 and 270 × 10^4/ha） of wheat Mianyang 26（cv）. The results showed that the contents of nitrogen accumulated in ear, culm and leaf were more in S-3307 treatments than in control, and the effect of S-3307 on main stem was bigger than that on tiller. The grain protein was significantly higher in S-3307 treatments than in control. With the increase of S-3307 concentration, the contents of grain protein albumin and globulin were significantly increased, the effect of 20 mg/kg S-3307 （B3） was the best, and the contents of gliadin and glutenin also increased. It suggested that the grain protein is regulated through nitrogen source regulation by S-3307.
