濒危植物小沙冬青研究进展

Research progress on rare and endangered plant Ammopiptanthus nanus

小沙冬青(Ammopiptanthus nanus (M. Pop.) Cheng f.)是荒漠干旱极端环境下唯一的常绿阔叶灌木,也是抗逆性研究的优秀指示植物材料。本文在查阅文献的基础上,对小沙冬青的群落生态学、解剖学、生殖生态学及遗传多样性、逆境胁迫下小沙冬青的生理及分子生物学响应方面的研究进行了综述,旨在为该植物资源的开发利用、荒漠区物种多样性的维持和生态环境建设提供借鉴。

Ammopiptanthus nanus(M.Pop.)Cheng f.is the only evergreen broad-leaved tree species in the extreme arid desert environment,which makes it an excellent plant material for research on plant stress resistance.In this paper,we summarize the community ecology,anatomy,reproductive ecology,genetic diversity,physiological,and molecular biological responses to stress of A.nanus.The purpose of this study was to provide references for the development and utilization of A.nanus,maintenance of species diversity in desert areas,and construction of the ecological environment.
