摘 要 ：以梭梭无菌苗和肉苁蓉萌发种子为材料，对肉苁蓉离体寄生培养基质、离体寄生方式和离体寄生环境条件等进行了研究，以明确肉苁蓉的寄生特性，为肉苁蓉人工繁殖技术体系的建立与优化奠定基础。结果表明：玻璃纤维滤纸是肉苁蓉离体寄生适宜的培养基质；在黑暗、相对湿度80%、温度18℃~30℃的环境中，萌发的肉苁蓉种子与寄主梭梭寄生培养8 d后开始建立寄生关系，寄生率达82%；而光照条件下，萌发的肉苁蓉种子与梭梭不能建立寄生关系。

Abstract:In order to identify parasitic property and to provide foundation for construction and optimization of manual propagation technology of Cistanche deserticola,we studied the medium,method and surroundings condition of in vitro parasitism with aseptic seeding of Haloxylon ammodendron and germinate seed of C.deserticola.The results showed that glass fiber filter was suitable culture medium of in vitro system parasitism of C.deserticola.Under condition of dark,relative humidity at 80% and temperature between 18℃~30℃,germinated seed of C.deserticola parasite H.ammodendron for 8 days,and the highest parasitism rate was 82%.But germinated seed could not parasite H.ammodendron under light condition.
