摘　　要：赖草属是多年生禾本科植物,在中国的分布地域较为广泛。该属内植物对逆境具有较强的抗性,尤其是对于干旱、盐碱、高寒和病虫害等有较强的抵抗能力。综述了近年来赖草属植物抗逆性方面的研究进展,从赖草的耐旱性、耐盐性、耐寒性以及抗病虫害等方面对赖草属植物的抗逆性机理进行了探讨,并对其未来应用做出了展望。Leymus is a perennial gramineous plant that widely spreads in China. It has a very strong resistant capabihty, especially to drought, salt, freezing, plant diseases and insect pests. The advances related to its resistant capability in recent years were presented. The reason and mechanism of its stress response that make it survive in the adversity including drought, salt, freezing, plant diseases and insect pests was summarized and discussed in details. Furthermore, its future development and application were also prospected.
