| ABSTRACT Growing orchids has been classified as an international business since it covers 8% of the world floriculture trade. Thus, large-scale micropropagation of orchid using tissue culture techniques and improvement of some essential traits, such as resistances to various diseases and pests, and tolerances to environmental stresses, such as low temperatures and low light intensities, via genetic engineering acknowledged the orchids as one of the top ten cut flowers. Protocorm-like bodies (PLBs) are excellent explants for clonal propagation, artificial seeds development and genetic engineering since they are organized and easily regenerable somatic embryos that propagate rapidly.
