摘要
17份野生大豆的盆栽试验结果指出,野生大豆在结瘤固氮方面存在着明显的基因型差异。花期根瘤数、根瘤鲜重和固氮酶活性与单株叶片含氮量呈显著或极显著的正相关,固氮酶活性与单株籽粒氮产量呈正相关,分枝期、花期、结荚鼓粒期的相关系数分别为0.401,0.478和0.512。
The pot experiment was conducted to determine the nitrogenase activity of 17 genotypes of wild soybean.The results showed that the formation of root nodulse and nitrogenase activity were different significantly among the genotypes.The number and fresh weight of root nodules and the nitrogenaes activity were positive marked of highly marked correlated with N content of leaves at flowering stage.The positive correlation was also found between the nitrogenase activity and N yield of grains at the branching,flowering and pod-bearing stages,and the correlation coefficients were 0.4012,0.4781*,0.5123*,respectively.
