High post-transplantation tree mortality is an important limitation in efforts to enhance tree cover in Canadian cities, one resultingx000D
in large costs to municipalities and tree owners. Lallemand Plant Care has developed several products that enhance plant stressx000D
resistance in agricultural crops, two of which may have important application in urban forestry due to their mitigation of droughtx000D
stress; Bluestim (Glycine betaine) and Rhizocell (Bacillus amyloliquefaciens IT-45) inoculants. Individually, one works to stimulatex000D
root growth and improve nutrient uptake, while the other enhances normal functioning of photosynthesis and translocation of waterx000D
and nutrients during environmental stress (i.e. high or low temperatures, water stress, saline/sodic soil), conditions commonlyx000D
faced by newly-planted trees in urban settings. Research is needed to investigate the potential for these agents to interact whenx000D
combined with standard endomycorhizzal inoculations (Glomus intraradices) to mitigate planting shock and tree stress normallyx000D
experienced during street tree establishment. Based on their modes of action, it is predicted that the two agents will have ax000D
positive, synergistic effect on tree seedling growth, one that will enhance individual vigour and survival. When combined, it is alsox000D
likely that they will confer improved stress and pest tolerance, however both greenhouse and field trials designed to elucidate thex000D
exact physiological mechanisms and extent of improvement are needed in order to demonstrate commercial application. Ifx000D
successful, this approach will provide a breakthrough of great significance to both Lallemand and the growing number ofx000D
municipalities across Canada in desperate need of better tools to enhance urban greening.
