Quinoa (Chenopodium quinoa Willd.) plants possess epidermal bladder cells (EBCs) on the leaf surface that accumulate excess sodium (Na⁺). However, whether excess cesium (Cs⁺) is transported from the leaf to the EBCs has not been elucidated in quinoa plants. In this study, the Cs⁺ concentration of EBCs and leaves of quinoa plants grown in soil treated with high concentrations of NaCl was investigated via pot experiments. Three different treatments were performed: 9.75 g plot, and 19.50 g plot, and a control (with no added NaCl). In 9.75 g plot and 19.50 g plot, 9.75 g and 19.5 g of NaCl were applied to the soil, respectively. And 0.10 g of CsCl were applied to all pots. We observed that Na⁺ concentration in EBCs and leaves with and without EBCs increased with increasing NaCl concentration at the vegetative and flowering stages; Na⁺ concentration was lower in the EBCs than in both types of leaves at both growth stages. Cs⁺ concentration in EBCs and both types of leaves increased with increasing NaCl concentration; Cs⁺ concentration was higher in EBCs than in both types of leaves at both growth stages. However, NaCl application did not affect the number of EBCs at both growth stages, but the number of EBCs in older leaves was lower than that in younger leaves at both growth stages. Moreover, EBC diameter increased with NaCl application at both growth stages; the EBCs of younger leaves (1st leaf) were larger than those of older leaves (5th leaf) at both growth stages. Therefore, NaCl increased the Cs⁺-accumulation capacity of quinoa plants by increasing the size of the EBCs.

藜麦（Chenopodium quinoa Willd.）植物的叶表面具有表皮膀胱细胞（EBC），可积累过量的钠（Na ⁺）。然而，在藜麦植物中，过量的铯 (Cs ⁺ ) 是否从叶子转运到 EBC 尚未阐明。在这项研究中，通过盆栽实验研究了在高浓度 NaCl 处理的土壤中生长的藜麦植物的 EBC 和叶子的Cs ⁺浓度。进行了三种不同的处理：9.75 g 图、19.50 g 图以及对照（未添加 NaCl）。在9.75克小区和19.50克小区中，分别向土壤施用9.75克和19.5克氯化钠。所有盆均施用 0.10 g CsCl。我们观察到，在营养期和开花期，EBC 以及有和没有 EBC 的叶子中的Na ⁺浓度随着 NaCl 浓度的增加而增加；在两个生长阶段，EBC 中的Na ⁺浓度均低于两种类型的叶子。 EBCs和两种类型叶片中的Cs ⁺浓度随着NaCl浓度的增加而增加；在两个生长阶段，EBC 中的Cs ⁺浓度均高于两种类型的叶子。然而，施用 NaCl 并不影响两个生长阶段的 EBC 数量，但两个生长阶段老叶中的 EBC 数量均低于新叶。此外，在两个生长阶段，EBC 直径都随着 NaCl 的施用而增加；在两个生长阶段，幼叶（第一叶）的 EBC 均大于老叶（第五叶）的 EBC。因此，NaCl通过增加EBC的大小来增加藜麦植物的Cs ^{+积累能力。}
