ECOLOGICAL ASPECT:

Nothing listed.

Plant conservation:

A growing demand of

Z. armatum

has caused a serious reduction in native population as a consequence of over harvesting and deforestation. As a result, target species

has been reported as a “endangered” species as

per International Union for Conservation of Nature (IUCN) criteria (Samant et al., 2007).

Natural regeneration mainly takes place through seeds. Seed germination is the easiest method but in Zanthoxylum, it is not uniform and takes few months to years for germination and establishment of seedling that is, exhibit strong dormancy apparently imposed by seed coat (Bonner, 1974). So propagation through seeds accounts for longer interval
