Abstract  The psammophyte resists drought by different mechanisms. Aristida Pennata Trin, a typical psammophyte, can resists drought by a root set which comes from viscid material secreted from its root. The sterile seedling is raised in the laboratory to investigate the structure of its root set under optical microscope and electron microscope. The result shows that the root set is formed of viscid material secreted from its root, and its main part is a chamber which is segmented a few little rooms. Aristida Pennata Trin may store water in the chamber to resist drought.
Key words:  Stipagrostis pennata Trin      root set      drought resistance mechanism
