稀植栽培条件下春小麦品质变异及其与产量的关系

以8个春小麦品种为供试材料,分析了春小麦在稀植栽培下的品质变化及其与产量关系。结果表明,稀植化栽培处理对籽粒千粒重和容重有显著的正相关作用,蛋白质含量、面筋指标和沉降值多数品种差异不显著。产量和蛋白质含量在稀植栽培条件下呈不显著负相关,其中龙麦26、龙麦29两个品种对产量和品质关系协调较好,其次是东农97-4056、克丰6、东农122、龙麦20。

Study on quality variation and relationship between quality and yield in spring wheat under lower density cultivation

The relations among quality characters and relations between quality and yield of spring wheat were analyzed with 8 spring wheat varieties under lower density. The results indicated that, in condition of lower density. Thousand kernel weight and test weight among spring wheat varieties showed positive correlations. Protein content, gluten characters and Sedimentation value among some varieties do not show significant. The negative correlations between yield and protein content were not significant, the relations between quality and yield of Longmai26, Longmai29 showed better than Dongnong97-4056, Kefeng6. Dongnong,122, Longmai20.
