Preliminary Study on the Mechanism for Adaptation of Stipagrosits Pennata to Desert

Psammophyte can resist drought through different mechanism, such as small and thin leaves, leaves covered with wax, well developed roots. As typical psammophyte, stipagrosits pennata’ root form entwined structure with sand, therefore shows excellent drought tolerance. This paper describes the mechanism of the adaptation of stipagrosits pennata to desert from different aspects such as morphology, anatomical structure and stress simulation.
