摘 要 ：花生品种间根瘤量的变化有显著差异,但每克根瘤中固氮酶活性则差异不显著。固氮酶活性在全生育期出现两次高峰,分别在下针期和结荚期,而单株根瘤中固氮酶活性和单株根瘤量均在结荚期出现一次高峰。花生主茎复叶硝酸还原酶活性(NRA)在生育前期出现一次高峰,其活性的高低与品种耐肥性呈负相关。NRA 和根瘤中固氮酶活性有正相关

Abstract:Studies on the nitrogenase activity(NA)and the nitrate reductase activity(NRA)in the nodules of groundnut revealed that although the number of nodules and noduleweight of different groundnut varieties were significantly different from each other,thedifferences among the NA of each gram of nodules of
