以苏玉糯5号和豫糯7号为材料，于2014、2015两年研究了开花前后渍水对鲜食糯玉米籽粒产量和食用品质的影响。开花前后的渍水降低了籽粒鲜重、体积和数量，导致鲜粒产量损失。授粉前渍水降低了籽粒含水率，增加了籽粒干重。渍水增加了淀粉含量，降低了蛋白质含量，尤其是授粉后；降低了清蛋白和谷蛋白含量，但不影响球蛋白含量。授粉前和授粉后渍水处理分别降低和增加了玉米醇溶蛋白的含量。不同种植年限、不同品种、不同受涝阶段的淀粉粒大小和碘结合力对受涝的响应不同。渍水对糊化温度和糊化温度的影响较小。淹水使苏玉糯5号在两个阶段的峰值粘度都增加，但这一参数降低。
The effects of waterlogging around flowering stage on the grain yield and eating quality of fresh waxy maize were studied using Suyunuo5 and Yunuo7 as materials in 2014 and 2015. Waterlogging around flowering stage decreased the fresh weight, volume, and number of grains, which led to the loss of fresh grain yield. Waterlogging before pollination reduced grain moisture content and increased grain dry weight. Waterlogging increased starch contents and decreased protein contents, especially after pollination; decreased albumin and glutenin contents; and did not affect globulin content. Zein content was decreased and increased, respectively, by waterlogging before and after pollination. The responses of starch granule size and iodine-binding capacity to waterlogging were dependent on planting year, variety, and waterlogging stage. Pasting and gelatinization temperatures were only slightly affected by waterlogging. Waterlogging increased peak viscosity at both stages in Suyunuo5, but this parameter decreased ...
