Cytochemical characterization of infection and resistance mechanisms in various host-pest relationships


  1. Gain insight into the resistance of Pinus banksiana and P. contorta to the European race of scleroderris canker.
  2. Study the mode of infection of Phytophthora ramorum, the causal agent of Sudden Oak Death.
  3. Study the role played by traumatic resin canals in the defense response of Norway spruce and eastern white pine to white pine weevil attack.
  4. Identify and locate growth regulators (e.g. abscisic acid) involved in defence mechanisms.
  5. Study the callus formation responses in elm following inoculation of the causal pathogen of Dutch elm disease.
  6. Prepare syntheses, such as the one currently under way on Dutch elm disease in Canada, encompassing its distribution, effects in the urban environment and research efforts.
  7. Characterize the differentiation that occurs in the wood of Populus tremuloides in response to forest tent caterpillar attack.
  8. Effect of various hormones on post-tapping defense reactions in sugar maple.
  9. Study how new preservatives penetrate and protect wood against decay organisms.
