Abstract

The objective is to determine the influences of, and the interactions between, mycorrhizal infection and elevated atmospheric CO2, in the important invasive weeds of pastures Senecio jacobaea (Ragwort). The impact of infection and CO2 concentration upon phenology, fecundity, assimilation of carbon and its allocation to plant, fungal mycelium and soil, and upon phosphorus uptake efficiency will be determined by growing plants through complete life-cycles in a split glasshouse with ambient and raised CO2, with and without mycorrhiza and at different nutrient levels. Responses will be determined by sequential harvesting, growth and tissue analysis, with inter-harvest measurements of gas exchange and carbon allocation using IRGA and tracer techniques.
