EFFECTS OF HANDLING AND SURGICAL TREATMENTS ON NITROGENASE ACTIVITY IN ROOT NODULES OF ALNUS GLUTINOSA, WITH SPECIAL REFERENCE TO THE APPLICATION OF INDOLE-ACETIC ACID

Authors


SUMMARY

The possible effects of applied indole-acetic acid upon nitrogenase activity and respiration in alder nodules could not be distinguished from the effects of the manipulative procedures themselves. The extent to which plants were handled during the acetylene reduction assay had a large inhibitory effect upon the apparent nitrogenase activity of the nodules.
