Stimulation of pine oleoresin flow by fungus inoculation

  • Russell B. Clapper
Original Research


Since the early 1930’s it has been known that application of certain chemicals to tapping surfaces on pine trees will stimulate the flow of oleoresin, and industrial use of a 50% sulphuric acid spray for this purpose is increasing. Now, investigations, discussed here, indicate that some stimulation may be achieved by inoculation with a fungus.
