Changes in the defence compounds pyrrolizidine alkaloids (PAs) in roots and shoots of Senecio jacobaea are reported in response to nutrient addition in order to investigate whether changes in concentration are adaptive. PA concentrations were examined in leaves and roots of 40 vegetative ragwort plants, subjected to four nutrient treatments in a climate chamber study.
