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.

Highlights

Different species of Ginseng are grown in different parts of the world having its own origin from a particularHow to cite this paper: Jamir, S
The lowest morphogenetic response was registered in 2012 where ~19.44% rhizome segments potentiated morphogenetic response and formed plantlets while in 2014, the response increased to 51.72%
Different parts of the plant such as Strychnos henningsii stem and root cuttings (Kipkemoi et al, 2013), Eucalyptus globules stem cuttings (Wilson, 1993), Triplochiton scleroxylon stem cuttings (Leakey, 1983), Warbugia ugandensis stem rooting (Kuria et al, 2010), Paris polyphylla (Deb et al, 2015) have been used for macropropagation for conservation programme and likewise propagation of Panax pseudoginseng through rhizome cuttings was found to be applicable for macro propagation of the plant species

Summary

Introduction

Different species of Ginseng are grown in different parts of the world having its own origin from a particularHow to cite this paper: Jamir, S. Different species of Ginseng are grown in different parts of the world having its own origin from a particular. Panax pseudoginseng Wall., a highly medicinal plant, originates from Nepal and the Eastern Himalayas (India) (Yun, 2001) and is known by the common name as the Himalayan Ginseng. Panax pseudoginseng is highly medicinal, herbaceous and long lived plant species that grows in the forest litter of shady primary forest. The plant roots of Panax pseudoginseng are widely use in local medicines in its dried powdered form for different ailments such as for diarrhea, dysentery, high blood pressure and for impotency (Jamir et al, 2012)
