a
Results are numbers of nodules per plant 21 days after inoculation (mean ± standard deviations; n = 4). All nodules were pink, indicating the presence of Lb. Control plants (uninoculated) had no nodules.
b
Numbers in parentheses show the nitrogenase (acetylene reduction) activity in nmol C2H4 plant−1 h−1 for 1 to 4 plants.
