Biomass of plantlet and nodule and nodule nitrogenase activities.

Fresh weights of above-ground sections of hairy roots at 35 d after inoculation. Nodules were harvested at 35 d after inoculation. The data represent the mean ±SE of three independent experiments. Significance of the data was analyzed using independent-samples T test.*, indicate the means in the same vertical column were significant at PBiomass of plantlet and nodule and nodule nitrogenase activities.
