摘要
以不同筋力型小麦品种为材料,研究了稻茬小麦3个不同播期(S1、S2、S3)对其籽粒品质性状的影响。结果表明:小麦不同播期间S1(10月8日)的总淀粉含量和支链淀粉含量最大,分别为74.37%、56.48%,S3(10月28日)的最小,分别为71.84%、54.06%;直链淀粉含量表现为S2(10月18日)最大(18.23%),S3最小(17.79%);淀粉直/支比以S2最高(0.333),S1最小(0.317);籽粒总蛋白质含量和谷蛋白含量以S3最大,分别为11.65%、4.55%;清蛋白和球蛋白含量以S1最大,分别为2.17%、1.43%;谷/醇比则是随播期推迟而增加;小麦面粉吸水率、面团形成时间、粉质参数均以S1最大,分别为64.73%、3.57min、66mm,S3最小;弱化度则以S3最大(117FU),S1最小(84FU);而稳定时间以S2最大(4.77min),S3最小(3.38min)。不同筋力型品种各指标间表现不一。沿黄稻茬麦区适宜栽培中筋和弱筋小麦品种,中筋品种适期早播,弱筋品种则适宜晚播。
In the experiment, the winter wheat varieties with different gluten types were grew in paddy field along Yellow River in Henan province to study the effects of different sowing dates （S1〉S2〉S3） on grain quality traits. The result showed that the effects of sowing dates on grain starch content and its components,protein content and its components, and farinograph parame- ters were significant. Among 3 sowing dates, the grain starch content and amylopectin content showed a dynamic of S1〉S2〉S3,the amylose content showed a dynamic of S2〉S1〉S3,and the ratio of amylose to amylopectin had a dynamic of S2〉S3〉S1. The contents of total protein and glutelin had a dynamic of S3〉S1〉S2,while the contents of albumin and globulin showed a dy- namic of S1〉S3〉S2. The ratio of glu/pro increased with the delay of sowing date. S1 obtained the highest values and S3 got the lowest values for flour absorption and forming time, but for softness S3 got the largest value and S1 the smallest. All the indices were different among the cul- tivars with different gluten types.
