[ Metbod] A total of 36 crosses were developed from nine inbred lines, according to complete diallel crossing design. The NDF contents and proportion of dry matter in different organs were statistically analyzed. [ Result] The NDF contents were significantly different between different organs of silage corn, and the proportion of dry matter and NDF content had significant correlation in different organs. The wholeplant NDF content was positively correlated with the proportion of dry matter in straw, stem and leaf as well as bract and spike-stalk, but it was negatively correlated with the proportion of dry matter in ear. [Conclusion] TO reduce NDF content in straw and to increase grain yield are efficient ways to improve quality of silage corn.展开更多
对添加玉米高品质膳食纤维(corn high quality dietary fiber,CHQDF)的面包质构特性进行研究。结果表明,添加CHQDF对面包质构特性有一定影响,可增大面包硬度和咀嚼性,而对面包弹性和回复性影响较小;通过对面包物性、比容、保水性、老化...对添加玉米高品质膳食纤维(corn high quality dietary fiber,CHQDF)的面包质构特性进行研究。结果表明,添加CHQDF对面包质构特性有一定影响,可增大面包硬度和咀嚼性,而对面包弹性和回复性影响较小;通过对面包物性、比容、保水性、老化度及面包感官品质进行综合分析,确定CHQDF在面包中最大添加量为9%;此时面包口感细腻、质地柔软、呈有弹性、风味纯正。展开更多
