The results showed that highly significant differences were observed between the two nitrogen treatments and also among family lines in the 4 nutrient contents. Applicating nitrogen may increase the contents of CP and CF in stalk, but decrease the contents of ADF and NDF. The variance segregation of stalk nutrients of F2∶4 lines were in normal distributions and with over parent segregation in some degree. The sensitivity to nitrogen fertilization varied with maize genotypes.

结果表明，两种氮肥处理之间以及不同家系之间各营养成分含量差异均达极显著水平；增施氮肥有利于提高秸秆的粗蛋白和粗脂肪的含量，降低酸性洗涤纤维和中性洗涤纤维的含量；两种氮水平条件下，不同家系之间秸秆各主要营养成分含量的变异性分离均符合正态分布，并存在不同程度的双向超亲分离；不同基因型的玉米对氮素的敏感性各异。

The nascent product distributions of CaH have been found with a Boltzmann rotational temperature of 1012±102 K and 834± 70K for the v=0 and 1 levels, respectively, and summations of the=(0,0) and=(1,1) rovibrational intensities separately show that the population ratio of CaH(v=0)/CaH(v=1) yields a value of 3.97+0.26, which corresponding to a Boltzmann vibrational temperature of 1313±173 K.
