Abstract
Eight winter wheat genotypes,NR9405,9430,Yanshi 9,Xiaoyan No.6,San 229,Xinong 2208,Aifeng 3 and Sang 188,were used as indication crops to study the effects of genotypes and nitrogen fertilizer application rate(0,90Nkg/hm~2) on the wheat nitrogen assimilation,the cumulative fraction of dry matter,yield and yield components.The results showed that there were significant differences of genotypes on the nitrogen concentration of leaves,stems,hull and rachis,grain at maturity,nitrogen harvest index(NHI),the cumulative fraction of dry matter allocated to the leaves,stems,grains,which were not significantly effected by nitrogen application rate.There were significant differences of genotypes on the total nitrogen assimilation(NTA),grain yield,the number of ears per unit area,the number of tillers per plant,kernels per spike,kernels of unit area,1000 kernels weight,grain mass per ears.The consequence of wheat yield increasing was that nitrogen application increased the plants per unit area,spikes per unit area,the number of tillers per plant,kernels of unit area and grains of unit area.Meanwhile,nitrogen application improved the dry matter accumulation as well as the total nitrogen assimilation,but it did not increase the grain nitrogen content.
