Study on Nitrate Reductase and Nitrite Reductase Coupled Regulation of Sugar Beet
The diploid variety,Shuangfeng 8 was used to investigate the effect of different ratio of nitrogen forms on NRA and NiRA,the total nitrogen content and sucrose content of root,and to discuss the coupled relationship between NR and NiR.Results showed that NR activity (NRA) and NiR activity (NiRA) changes was the two-peak curve,and the changing trend was basically consistent and the coupled relationship was observed obvious.The total nitrogen content of root showed the two-peak curve,which was significantly positive or extremely-significant positive correlated with NRA or NiRA.Sucrose content displayed a single peak curve,which was basically complementary with total nitrogen content curve.
