The results showed that both in Yumai49 and Yumai66, valueof total organic matter (TOM) of noodle and noodle cooking loss rate ranked the firstwhile noodle score (NS) ranked the lowest in treatments without any nitrogen application.As nitrogen application rate increased, TOM value decreased but NS increased. The lowestTOM and the highest NS existed for treatments with 225 and 150 kg N ha-1 in Yumai49 andYumai66, respectively. Increasing irrigation resulted in greater TOM and NS, but lessbroken noodles. However, no significant difference was found in NS among differentirrigation treatments. Significant difference was found in TOM, NS, breaking rate andwater absorption rate of noodle between these two cultivars. Yumai49, with an average TOMvalue of 1.19 g and NS of 88.5, was better than Yumai66, with an average TOM value of1.55 and NS of 85.7. Interaction in TOM value was found between irrigation and nitrogenapplication. Effects of nitrogen fertilization were greater than that of irrigation inYumai49, while in Yumai66 the other way round. It is suggested, therefore, thosedifferent irrigation and nitrogen application regimes be chosen in production practicebased upon cultivar quality traits.展开更多
在大田条件下,研究了不同施氮水平对豫麦49-198和兰考矮早八面粉色泽及面条品质的影响。结果表明,两品种面粉及面糊的色泽等级值(CGV)、红色度(a*)和黄色度(b*)随施氮量的增加而增大,亮度(L*)随施氮量的增加而下降。随着放置时间的延长...在大田条件下,研究了不同施氮水平对豫麦49-198和兰考矮早八面粉色泽及面条品质的影响。结果表明,两品种面粉及面糊的色泽等级值(CGV)、红色度(a*)和黄色度(b*)随施氮量的增加而增大,亮度(L*)随施氮量的增加而下降。随着放置时间的延长,面片的CGV、a*、b*升高,而L*值下降。质构仪分析表明,随着施氮量的增加,两品种面条的硬度、黏合性、咀嚼性呈上升趋势,以360 kg hm-2处理的值最高,并且和其他处理之间的差异达显著水平。展开更多
