Area of expertise
Mineral nutrition and cold tolerance of tree seedlings
Research
- stress tolerance of trees
My research interests are in the field of tree physiology. I am particularly interested in how temperate and boreal trees adapt and acclimate to the stresses of low temperature and low levels of available nitrogen. To distinguish between adaptation and acclimation, I explore the interaction of genetic and environmental components of tree response to nutrient stress and cold stress. I study the association of trees with ectomycorrhizae and how ectomycorrhizal diversity allows trees to access various pools of nutrients in forest soils.
Recent projects
- Studies of net fluxes of ammonium, nitrate and protons along the length of conifer seedling roots; and how these fluxes are affected by species, genotype, nutrient status of the plant, and pH and nutrient concentration of the root medium.
- Co-adaptation of conifers and their mycorrhizal partners to soil nutrients
- Assessment of the phenology and cold hardiness of shoots and roots of yellow cypress seedlings from the provincial tree improvement program.
