Bamboo is one of the most versatile and unique groups of plant species known to mankind. It is generally recognized as a very useful indigenous product for majority of the rural population. It has also tremendous potential in various agroforestry systems, especially bamboo-based agroforestry on degraded lands. Various species of bamboo occupies a supreme position priority for its value as a raw material for the pulp and paper mills and other commercial, rural and household uses. It provides food, raw material, shelter, medicine and aesthetic use. It has been increasingly commercialized during the recent years. Natural genetic resources of bamboo are getting depleted very rapidly and there is much more demand than supply therefore its plantation activity is increasing globally. Global scarcity of bamboo seeds is widely known and well documented fact. Nevertheless, among the several methods of propagating bamboo on a large scale, seeds still considered being the most reliable method. However, various methods and their potential in multiplication of bamboo on semi large scale have been reviewed. Currently macroproliferation of seedlings of Bambusa arundinacea, Bambusa tulda, Dendrocalamus strictus and Dendrocalamus hamiltonii have been also investigated. Mineral nutrients applications on nursery seedlings of macroproliferated bamboo have significantly affected growth and rhizome biomass and proliferation rates. Several reports deal with nursery management practices in order to have healthy stocks of bamboo. Other traditional vegetative methods practices seem to laboratory practice and suffer from limitation of early flowering. Propagation of bamboo by conventional methods such as by off shoots, rhizome planting, culm cutting, layering are considered slow, time consuming and the percentage of rooting is also very low. Therefore, to meet the acute shortage of planting stock, tissue culture plays an alternative means and important role to regenerate innumerable numbers of plants. During the recent years a lot of emphasis has been laid on micropropagating bamboo through somatic embryogenesis as it is believed to involve rejuvenation. The present communication deals with the scarcity, demand, and protocol of in vitro clonal propagation of six bamboo species (Dendrocalamus asper, D. membranaceus, D. strictus, D. giganteus, Bambusa arundinacea and B. vulgaris) that have been undertaken on large scale multiplication. By using this methodology, large numbers of bamboo plantlets were developed and successfully established in the field.
