Abstract

Orchids are popular plants because of the wide range of colors, shapes, sizes, and fragrances of their flowers. The demand for orchids as cut flowers and pot plants is ever increasing in the market. The survival and subsequent germination of orchid seeds are comparatively low in the wild. Thus, to meet the demand of the horticultural industry, the in vitro germination of orchid seeds needs to be performed. Although tropical orchids can germinate on relatively simple media, the temperate orchids might require complex media or the presence of a symbiotic fungus. This chapter focuses on two common micropropagation methods using seed and protocorm-like body (PLB) cultures, respectively. For seed culture, the micropropagation of Cypripedium macranthos is detailed. Regeneration of orchids can also be achieved using protocorms or PLBs from vegetative explants. PLBs are excellent explants for clonal propagation, artificial seed development, and genetic engineering because they are organized and easily regenerable somatic embryos that propagate rapidly. Here, the development of PLBs from leaf sections and root tips of Phalaenopsis orchids is also described.
