| 摘 要： | 【目的】研究遮阴处理对不同冬小麦品种籽粒灌浆及品质特性的影响,为耐阴小麦选育提供理论基础。【方法】在大田灌溉条件下,以新冬20号、新冬40号、新冬57号和新冬60号为材料,分别设置自然光对照和遮光度为50%的遮阴处理,研究不同冬小麦品种在遮阴和自然光条件下籽粒灌浆特性、品质特性及产量的变化规律。【结果】 遮阴处理后,四个冬小麦品种的籽粒灌浆特性表现为:新冬57号＞新冬60号＞新冬40号＞新冬20号,各品种的蛋白质含量、湿面筋含量和沉降值均表现为:新冬20号＞新冬57号＞新冬40号＞新冬60号;新冬57号的形成时间最长,为5.7 min;新冬60号的稳定时间最长,为11.6 min;面团拉伸特性表现为:新冬60号＞新冬20号＞新冬40号＞新冬57号;产量表现为:新冬40号＞新冬57号＞新冬20号＞新冬60号。【结论】遮阴显著降低了四个冬小麦品种的灌浆特性及产量,对品质特性也有一定的影响。

| Abstract: | 【Objective】 This project aims to study the influences of shading treatment on the grain-filling and quality characteristics in different winter wheat varieties in the hope of providing a theoretical basis for the shading-tolerant wheat breeding.【Method】Take the Xindong 20,Xindong 40,Xindong 57,Xindong 60 as the experimental materials under the field irrigation conditions. Set the natural light as CK and take the shading level 50% as the shading treatment respectively, to research the grain filling characteristics, quality characteristics and yield of different winter wheat varieties under the shading treatment and natural light.【Result】After shading treatment, the grain filling characteristics of the four winter wheat varieties were: Xindong 57 >Xindong 60 >Xindong 40 >Xindong 20, the protein content, wet gluten content and Sedimentation volume of all varieties showed as follows: Xindong 20 > Xindong 57 > Xindong 40 > Xindong 60; The development time of Xindong 57 was the longest, which was 5.7 min; Xindong 60 had the longest stability time, which was 11.6 min; the dough extensograph characteristics were: Xindong 60 > Xindong 40 > Xindong 20 > Xindong 57; The yield was: Xindong 40 > Xindong 57 > Xindong 60 > Xindong 20.【Conclusion】Shading significantly reduced the grain filling characteristics and yield of four winter wheat varieties, and at the same time, it also has an impact on quality characteristics. |
