To evaluate the phytoextraction efficiency of Gypsophila paniculata from Cs-contaminated soils and analyze the mechanism of Cs accumulation in G. paniculata, we analyzed the characteristics of Cs bioaccumulation and subcellular distribution, in addition to its chemical forms in the plant under hydroponic conditions. The results showed that total Cs content in the aboveground parts and the entire plant were as high as 6137.32 mg·kg⁻¹dry weight and 7338.49 mg·kg⁻¹dry weight, respectively, after 17 days in the 50 mg·L⁻¹ Cs treatment. The BCF was between 2.35 and 3.38. The TF was between 1.00 and 2.46 in G. paniculata. Subcellular distribution of Cs in the plant was as follows: soluble fraction > cell wall > organelles. Inorganic Cs (F-ethanol) and water-soluble Cs (F-dH2O) were the main types of Cs in G. paniculata. Further studies show that the phytoextraction efficiency can reach 10.30–11.91% planting a season of G. paniculata under potted conditions. The results suggested that G. paniculata, a perennial, drought-tolerant herb, was a high-accumulator of Cs, which may have potential uses in phytoremediation of Cs-contaminated soil.

为了评估的植物提取效率满天星从铯污染的土壤和分析在CS中积累的机制G.布渣叶，我们分析Cs的生物蓄积性和亚细胞分布，特点除了在水培条件下植物的化学形式。结果表明，在50 mg·L ^-1的土壤中，地上部分和整个植物的总Cs含量在17天后分别高达6133.72 mg·kg ^-1干重和7334.89 mg·kg ^-1干重。CS治疗。BCF在2.35和3.38之间。该TF在1.00和2.46之间G.穿心莲。Cs在植物中的亚细胞分布如下：可溶性部分>细胞壁>细胞器。无机Cs（F-乙醇）和水溶性Cs（F-dH2O）是G. paniculata中Cs的主要类型。进一步的研究表明，在盆栽条件下种植一季G. paniculata的植物提取效率可以达到10.30-11.91％。结果表明，多年生耐旱草本植物G. paniculata是Cs的高积累剂，可能在植物修复Cs污染的土壤中具有潜在用途。
