Appendix Species Propagation method Matrix
Section 1 Introduction to the manualBackgroundMedicinal plants constitute a considerably large component of natural vegetation. Several of these species are in great demand for domestic consumption as well as for commercial use by the herbal industry. About 800 species are estimated to be in trade with a turn over of Rs.4000 crores per year. Except about 60-80 species whose produce comes from cultivated sources, the rest of the raw material being traded comes from the wild collections. This high demand by the herbal industry has put enormous pressure on the wild populations leading to destructive collection of the produce. Absence of commercial cultivation of these species, results in increased dependence on the wild collections, which has further aggravated the situation. Today, a large number of medicinal plants species are considered threatened due to such high demand and destructive collection practices. Thus, the conservation efforts are of immediate need to save these species in the wild by maintaining their wild populations, without which the species may be wiped out. Propagation of such prioritised species in the nurseries is a means towards conserving their genetic stocks. Through the nurseries it is possible to make available planting material of these species for cultivation. Bringing more species under large-scale cultivation helps reduce the pressure on the wild stocks. However, in the absence of comprehensive information on the propagation techniques, nursery management and agro-technology of medicinal plants, the initiatives to establish medicinal plants nurseries and cultivate them asPropagation of Commercially Important Medicinal Plants 1
commercial crops have not witnessed considerable success in the past.
Manual and its purposeThis manual is a step towards bridging this gap. It has attempted here, to bring together the available information on the propagation techniques of 81 medicinal plant species and discusses the basic principles of plant propagation and nursery management. The species included in the manual are of the following category: Species, which are native and are suitable to the soil and climatic conditions of Andhra Pradesh. Species, which witness a high demand by the herbal industry and vigorously traded Species, which have a potential for commercial cultivation Species which witness a high degree of collection from the wild, hence require possible remedial measures to replenish the stock Species which are recommended by the local communities as they are found in the local trade Species which are already in cultivation to a certain extent Species, which are red listed, hence require possible remedial measures to replenish the stock The manual has tried to make available the information in a userfriendly style.
Propagation of Commercially Important Medicinal Plants
Objectives of the manualWhile doing so, the manual focuses on the following objectives. To make the VSS understand the significance of raising nurseries of commercially important medicinal plants To orient the VSS towards the techniques for raising and managing medicinal plants nurseries To familiarise the VSS with the propagation methods of commercially important medicinal plants species To provide an overview of the cultivation status of commercially important medicinal plant species
Structure of the manualWhile addressing these objectives, the manual has been structured keeping the needs of the VSS. In order to facilitate easy understanding, the information has been made available in two sections. The first section provides an overview of the cultivation and propagation of medicinal plants and illustrates the basic principles involved in plant propagation and nursery management. The second section describes the propagation techniques of the selected medicinal plants species. Information in this section is presented in the form of easy to follow step-by-step instructions.
How to use the manualThe manual is user friendly. It can readily serve as a training tool. The manual has to be referred and used by a VSS member as a reference guide for training and orientating the VSS and the local communities about the propagation of medicinal plants. The first section of the manual helps in discussing the necessary background information about the cultivation and propagation. It further orients the VSS to the principles of plant propagation. In thePropagation of Commercially Important Medicinal Plants 3
second section, a VSS can concentrate on its choice of species. Details of
