PIXE analysis of trace elements in relation to chlorophyll concentration in Plantago ovata Forsk

Plantago ovata Forsk – an economically important medicinal plant – was analyzed for trace elements and chlorophyll in a study of the effects of gamma radiation on physiological responses of the seedlings. Proton-induced X-ray emission (PIXE) technique was used to quantify trace elements in unirradiated and gamma-irradiated plants at the seedling stage. The experiments revealed radiation-induced changes in the trace element and chlorophyll concentrations.
