Abstract: The work showed that the highest nitrate reductase activity (NRA) appe-aedr in the functional period of each leaf on main stem of groundnut, which could last for a period(6days) and then dropped. In the whole growing period of groundnut, an obvious peak of NRA came out in seedling stage. In seedling stage NRA was inversely correlative with nitrogen response of varieties. Through measuring and assaying 6 varieties grown in field successively, the results showed that the mean value of NRA was inversely correlative with the nitrogen response of varieties, but directly correlative with the amount of NO-3-N in leaves and protein in seeds.So it was considered that NRA of groundnut could be used as an index in its biochemical breeding. In the treatment of N fertilizer as seed manure, the more N fertilizer was applied, the higher the amount of NO-3-N in seedling,stage, the lower the NRA.So it was concluded that N fertilizer could inhibit the NRA of seedling stage.
