Jarmo Holopainen, Professor of Applied Ecology from the University of Eastern Finland, Department of Environmental Science and his research group are doing multifaceted biological and ecological research. The research is related to biological and ecological effects of global change, plant-herbivore interactions, secondary chemistry of plants, biogenic volatile organic compounds and to formation and ecological effects of biogenic secondary organic aerosols. Recent publications range from defence pathways in Scots pine bark after feeding by pine weevil and biotic stress accelerating reactive emission of biogenic volatile compounds leading formation of climate-relevant aerosols in boreal forests, to plant-to-plant communication with volatile defence compounds.
Recently installed Valoya lights are used to e.g. study the effects of light quality on plant growth, production of phenolic and terpenoid compunds and fine structure of the plants. These pilot experiments are related to a project assessing the possibilities to use modulation of light spectrum for enrichment of secondary metabolites in plants.
