沙拐枣属植物的研究进展

沙拐枣属植物（Calligonum L.）作为我国荒漠地区的一种固沙造林先锋树种,具有抗旱、耐高温、耐瘠薄、抗风蚀沙埋、繁殖容易、适应性强、生长迅速、对干旱和流沙具有特殊适应性等特点。从种类分布、繁殖技术、化学成分、抗逆分子生物学及生态特性等方面对沙拐枣属植物的研究进展进行了综述,旨在为沙拐枣的荒漠治理、抗逆机理、基因资源挖掘等研究奠定基础。

Research Progress on Calligonum L.

The Calligonum L. is one of the most ecologically important resources in desert areas of China and is commonly used for dune fixation and afforestation. The Calligonum L. has a series of advantages, such as drought resistance, high temperature resistance, low soil fertility tolerance, wind erosion and sand burial resistance, easy propagation, strong adaptability, rapid growth, special adaptability to drought and shifting sand. The species distribution, propagation technique, chemical components, biological characteristics of stress resistance and ecological characteristics of the Calligonum L. were reviewed, so as to provide foundation for the study of Calligonum L. on desertification control, stress resistance mechanism and development of their genetic resources.
