摘要： 分析野生矮桃生物量分布规律，以及对硒与矿质元素的吸收、迁移及其相关性的探究。采取野生矮桃样本，测出其生物量；分别采用原子发光色谱法和原子荧光法，对不同居群的矮桃植株及土壤中矿质元素和硒元素进行测定，并进行相关性分析。结果显示：矮桃叶的生物量分配率最高，矮桃根和果实中的硒与钾含量成显著负相关，矮桃叶中的硒含量最高。为探究矮桃作为富硒植物开发提供了基本科学依据。

Abstract: The research analyzed the biomass distribution of uncultivated lysimachia clethroides and the absorbing ability, migration and correlation between the content of selenium and mineral elements； the samples of uncultivated lysimachia clethroides were gathered to measure the biomass. The contents of mineral elements and selenium were determined respectively by the atomic luminescence chromatography and the atomic fluorescent method，and the correlation analysis was done meantime. The result showed the biomass distribution rates in the leaves of the lysimachia clethroides were the highest, and the content of selenium was negatively correlated to potassium in the roots and fruits. Besides, the leaves possessed the highest content of selenium.
