Pot experiments were carried out to study the differences of root characteristics and the effects of nitrogen forms on root characteristics in two wheat varieties with different nitrogen uptake efficiency(NUE).

A recombinant inbred lines population(RILs)of 163 lines derived form a cross of Dasanbyeo(indiaca)/TR22183(japonica)was evaluated for analyzing inheritance of traits: nitrogen-absorbing ability and nitrogen-utilizing efficiency of rice at the maturity stage by the major genes plus polygenes mixed inheritance model of quantitative traits in plant.

Characteristics of N uptake and N recommendation for autumn Chinese cabbage in Beijing Suburb;

The results indicated that fresh ear and kernel yield,N uptake,and NUE were significantly different among varieties.

To understand the N uptake of weeds in wheat field to different N applications and the competition on the N absorption between weeds and wheat,plot trials were carried out in the semi-humid areas.

Process of nitrogen uptake by rice paddy ecosystem and its economic value.;

Effects of water deficit and nitrogen fertilization on winter wheat growth and nitrogen uptake

this experiment used Anthurium andraeanum as material and studied the effect of matrix moisture content on the growth、development and nitrogen uptake of Anthurium andraeanum.
