Title: Mycorrhizal inoculation: What worked and what did not work?

Summary: Poor health of urban trees reduces photosynthesis and growth, thus affecting the efficient storage of atmospheric carbon in woody biomass. Since large trees generally store far more carbon than young plantings (Sillet, 2008), the arborist’s goal is to facilitate the highest rate of survival after transplanting through ongoing health maintenance. This study investigates the effect of different strains of mycorrhizae-forming fungi specifically selected for different urban settings. Trees were inoculated with specific micorrhyzal inoculi according to the species and the environmental conditions. Trees in diverse growing conditions were tested. The presentation will include the variable results obtained so far according to the different species and environmental conditions.
