Analysis of salt secreted by the salt glands of Tamarix aphylla shows that the composition of the secreted salt is dependent on the salt composition of the root environment. Rubidium ion, if added to culture solutions in which the plants were growing, is also taken up by the plants and subsequently secreted by the glands. Electron micrographs of glands from the ribidium-secreting plants show accumulations of electron-dense material in the microvacuoles of the secretory cells. It is concluded that rubidium is accumulated in the microvacuoles and subsequently secreted by their fusion with the plasmalemma.
对无叶柽柳盐腺分泌的盐分分析表明，所分泌盐分的组成取决于根系环境中的盐分组成。如果向植物生长的培养液中添加铷离子，植物也会吸收并随后由盐腺分泌出来。分泌铷的植物盐腺的电子显微镜照片显示，分泌细胞的微液泡中有电子致密物质积累。得出的结论是，铷在微液泡中积累，随后通过与质膜融合而分泌。
