摘　　要：氮是影响产量最重要的元素之一。硝酸盐是植物吸收氮素的主要形式,硝酸还原酶(NR)是硝酸盐同化过程中的第一个关键酶,硝酸还原酶活性(NRA)作为育种程序中改良氮素吸收、利用效率的指标。本研究选取了100份不同质源的高粱材料,通过对100份高粱材料进行硝酸还原酶活性测定,为筛选高粱氮高效材料奠定基础。Nitrogen is one of the most important elements affecting yield.Nitrate is the main form of nitrogen uptake by plants. Nitrate reductase(NR) is the first key enzyme in the process of nitrate assimilation. Nitrate reductase activity(NRA) is used as an index to improve the efficiency of nitrogen uptake and utilization in the breeding program.In this study, 100 sorghum materials with different quality sources were selected, and nitrate reductase activity was determined on 100 sorghum materials, which laid a foundation for screening sorghum nitrogen efficient materials.
