| 摘 要： | Physiological studies of soybeanGlycine max(L.)Merr.]genotypes with wide differences in seed protein concentration may permit detection of important yield-related processes.In order to research the law of protein accumulation and the characteristics of N accumulation and translocation,we did an experiment with three soybean cultivars which have different protein content and the similar phase in pot culture.The results showed that the laws of protein accumulation of three soybean cultivars are similar in the course of seeding;protein content descended in the early stage,and increased steadily in the middle period,then increased quickly in the later period.But the speed of protein accumulation in soybean seeds was difference in different period.In addition,high-protein cultivar(Dongnong 42)and intermediate protein cultivar(Dongnong 7819)were more than those of low-protein cultivar (Dongnong 434),including nitrogen in leaf and petiole,stem and pod,peak value of nitrogen accumulation of the whol plant,value of nitrogen translocation,its efficiency.
