Abstract:
Dongnong 42 (high protein cultivar),Hefeng 25 (middle cultivar) and Dongnong 46 (high soil cultivar),were detected to compare their NR activities.The soybeans were planted in pots and fertilized with 0.033 g of N and K2O per kg soil,at the same time,four levels of phosphorous treatments were designed,which were P0、P5、P10、P15(i.e.,0、0.033、0.067、0.100 g of P2O5per kg soil).The NR activities was determined with in vitro method.In each cultivar under each treatment,NR activities in functional leaves were gradually decreased from seedling stage to ripening stage;In the same cultivars under each treatment,the highest NR activities in functional leaves were at P10treatment in high protein variety and middle variety,at P5treatment in high oil variety.In the same treatment with each species,the NR activities in functional leaves were the highest in high protein variety and the lowest in high oil variety.The highest NR activities in high protein variety showed the best nitrogen metabolic activity and the increase of protein content.
