Abstract Phalaenopsis orchids are recognized as the most popular orchid genus in the world, especially in horticultural industry due to their large, colorful, and durable flowers as well as their wider adaptability to room conditions. The characteristics of seedling propagated by vegetative means are not uniform; therefore, propagation through tissue culture is desirable. Although the micro propagation of Phalaenopsis has shown very good development, but the wide spread of micro propagation still limited due some problems such as the exudation of phenolic compounds, the PGR concentration, the media used, somaclonal variation, the chosen explants, etc. This paper endeavor to include some important investigations based on the common explants used; leaf and flower stalk.
