ABSTRACT: Panax pseudoginseng Wall., a highly medicinal, herbaceous, long-lived plant, grows in the
forest litter of shady primary forest. The species is threatened in the natural
habitat due to unsustainable harvesting of rhizome for medicine and habitat destruction.
The species has very poor adaptive power to the synthetic environment and fails
to grow and propagate. Present study was undertaken to develop suitable low
cost propagation technique and produce clonal planting materials through
rhizome splitting and root cutting. Rhizomes and roots were cut into segments and sowed in the raised soil bed prepared by
mixing decayed wood powder, sand and top black soil at 1:1:3 ratios in a
shaded poly house. Of the sowed rhizome segments ~55% segments remained recalcitrant
to morphogenetic response in the first year of the study and the response
improved in the subsequent years. In the third year ~51% rhizome segments
responded positively. The horizontal root cuts mostly remained morphogenetically
dormant but inclined root cuts exhibited better response. The morphogenetic
response from the roots was comparatively very poor compare to rhizome
segments. The plantlets formed both rhizome segments and root cuttings were
maintained for three years in the bed/pots followed by transferring in the
cultivated plots.
