摘要：

为研究不同产地肉苁蓉种子携带真菌优势菌群和带菌率的差异，采用平皿法对肉苁蓉种子进行外部（洗涤法和干种子法）、内部（种子消毒法与种仁消毒法）带菌检测。结果表明，肉苁蓉种子携带菌群主要为曲霉属（Aspergillus spp.）、交链孢属（Alternaria spp.）、镰孢属（Fusarium spp.）、青霉属（Penicillium spp.）及少量的散囊菌属（Eurotium spp.）。不同产地肉苁蓉种子携带菌群及带菌率差异不显著，但分离频率有一定差异。研究结果为肉苁蓉种子标准的制定提供参考。

Abstract:

To study the dominant seed-borne fungi of Cistanche deserticola seeds which were from different producing area. Petri-dish testing was used to determine the external (washing and seed) and internal (seed disinfection and seed kernel disinfection) seed-borne fungi of the seed. The result indicated that Aspergillus spp., Alternaria spp., Fusarium spp., Penicillium spp. and Eurotium spp. were the main seed-borne fungi of Cistanche deserticola. There was few difference in the type of the fungi among producing areas but differences in the isolation frequency of the fungi. It would provide a scientific basis for instituting standard of seed C. deserticola.
