Abstract
In order to investigate nitrogen dynamic change in high-protein soybean cultivar,the dynamic change of nitrogen accumulation,distribution and translocation and its effects on protein content in seeds were analyzed.Two high-protein and one common soybean varieties with similar yield were chosen as test materials and the nitrogen content in different organ after branching were determined and calculated.The results showed that the nitrogen content in 3 cultivars was similar before podding.After podding,the nitrogen content of all vegetative organs(leaf,stem and petiole)of high-protein cultivars,except that of petiole in the 7th week,were higher than those of normal cultivar.Therefore,the higher nitrogen content and maintaining for a long time in the vegetative organs were beneficial to nitrogen accumulation of seeds.On the contrary,nitrogen content in pod shell(with the exception of mature stage)of high-protein soybean was lower,which suggested most nitrogen in vegetative organs were translocated to seed in high-protein soybeans.During seed formation,translocated N contributed more to seed protein content for high-protein soybean.At maturity,the high-protein cultivars still could uptake more nitrogen than normal cultivar and the nitrogen content in all organs were higher than those of normal cultivar,which is favorable to the comprehensive utilization on both seeds and straw of high-protein soybean cultivars.
