Abstract:
OBJECTIVEThe quantity and genus of fungi on 13 samples of American ginseng seed from Beijing and Northeast area in China were detected.
METHODWashing and surface sterilization were used to isolate the fungi existed on seed surface and inside of the seed, respectively.
RESULTThe genera of the fungi in embryo and shell of the seeds mainly belonged to Fusarium spp., Alternaria spp., Penicilium spp., Cephalosporium sp., Rhizopus spp., and a small quantity of Mucor, Aspergillus, Tritroderma, Doratomyces and so on. The isolated fungal frequencies on the shell and in the embryo were 36%-100% and 40%-100% respectively.
CONCLUSIONThe fungal frequency of American ginseng seed was higher. There were significant differences among different seed samples, the main fungal genera and isolation frequency in the seed embryo were identical with the results from the seed shell.
