Abstract
The present PhD-Thesis deals with
the morphology and anatomy of the Korean ginseng plant, Panax
ginseng C. A. Meyer. The root system, leaves and fruits are
described, just as the morphological and anatomical particularities
and special features of different developmental stages (seed,
embryo, seedling, one-year-old plants and older plants). It is
shown, that conventionally used botanical terms do not deal with
all aspects of plant anatomy or morphology. Germination experiments
reveal, that modifiction of environmental determinants can be used
for only slight shortening of natural occurring ginseng diaspore
dormancy. But, these determinants were important for germination
rates. Treatment with gibberillic acid also stimulates germination
rates of Panax ginseng in a special way and reduces dormancy of
ginseng diapores. The second part of the thesis focuses on the
importance of arbuscular mycorrhizal fungi in ginseng cultivation.
Inoculation with 12 different AMF-isolates including the genera
Glomus, Acaulospora and Gigaspora were succesful, but there are
dependencies on inoculation procedures and plant age. The different
AMF-isolates give rise to growth stimulation effects on several
growth criterion. Most of the isolates enhance growth of the
ginseng plants, but some are causing growth depression. Substrates
at different nutrition regimes can modify growth stimulation
additionally. Finally, the usefulness of AMF in ginseng cultivation
is discussed.
