查询词典 wheat-straw

The authors determined glutenin protein,soluble in acid glutenin protein, surplus protein content in 21 species of wheat and indexes of rheological characteristics and made sedimentation and bread baking test. By using stepwise regression and path analysis methods,it was further proved that prediction of bread baking quality of wheat by Surplus protein content is more precise than that by sedimentaion and approximately equal to that by the score of flour. So the authors suggest that the direct selection of ...

本试验测定了21个小麦品种的几种蛋白含量以及流变学特性指标，作了沉淀试验和面包烘烤试验，借助于逐步回归分析和通径分析方法，进一步验证了用剩余蛋白含量预测小麦烘烤品质与评价值相当，比沉淀值准确的结论，并建议在小麦品质育种及面包烘烤品质分析中，加强对剩余蛋白含量的直接选择。

Composition of low molecular weight glutenin subunits and gliadins were investigated with thirty common wheat cultivars which are widely grown in Shangdong province. In our study we used acid polyacrylamide gel electrophoresis and SDS-polyacrylamide gel electrophoresis, analysed Sedimentation test, Protein content, Mixing time, Stability, Max-resistance to extension, Farinograph Quality Number and Extensogram area of the 30 common wheats. They have close relationship with the technology properties of noodle wheat cultivars.

本研究通过酸性聚丙烯酰胺凝胶电泳和SDS-聚丙烯酰胺凝胶电泳，分析了30个山东省种植面积较大且具有部分代表性的普通小麦品种的低分子量麦谷蛋白亚基和醇溶蛋白组成，测定了30个品种的蛋白质含量、沉淀值、面团形成时间、稳定性、粉质评价值、最大拉伸阻力和拉伸曲线面积等面粉及面团主要品质性状，分析了低分子量谷蛋白亚基和醇溶蛋白组成与面条小麦品质性状的关系。
