The orchids are habitat specific and their trade from naturally grown population has been banned by Government of India. The clandestine trade, however is continuing without any check. The desire for new and exotic colours and the demand in Japanese market, future sales of tropical orchids are likely to increase. Countries like Thailand, Singapore, Malaysia, Japan, Korea are now running multibillion dollar business in orchids using Tissue Culture technique. However, commercial orchid growing in India is yet to be properly organized. The book is primarily intended to be an useful laboratory tool for those who wish to make carrier either in research in the field of orchid tissue culture or in commercialization of orchids as an Industry.
