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.
在一项关于伽马辐射对幼苗生理反应影响的研究中，对经济上重要的药用植物卵叶车前（Plantago ovata Forsk）进行了微量元素和叶绿素分析。采用质子激发X射线发射（PIXE）技术对幼苗期未辐照和伽马辐照的植物中的微量元素进行定量分析。实验揭示了辐射引起的微量元素和叶绿素浓度变化。
