Abstract: Phalaenopsis spp. was regularly produced through micropropagation by protocorm like bodies (PLBs); micropropagation takes a lot of labor, and has high cost of seedlings, energy and material. The purpose of this paper was to study the new technique of using in vitro embryogenesis culturing for microprogation. The method involved using protocorm like bodies as planting materials. PLBs were cut into slices and placed on the medium for callus initiation. The callus was initiated on the medium MS + BA (0.1 mg/l) supplemented with NAA (1 mg/l) or 2,4D (1 mg/l) and was proliferated on the medium MS + BA (0.1 mg/l) supplemented with NAA (1 mg/l). Somatic cell suspensions were initiated and proliferated on the medium MS + BA (0.1 mg/l) supplemented with NAA (0.5, 1 mg/l). Somatic cell suspensions were differentiated to embryonic cell suspensions on the MS medium supplemented with NAA (0.1 mg/l) + BA (0.5 mg/l). Embryonic cell suspensions were plated and regenerated on the medium: 1/2MS supplemented with NAA (0.1 mg/l) + BA (0.5 mg/l). Micropropagation of Phalaenopsis sp. via the embryogenesis technique was set up to produce 5,800 plantlets per one liter of somatic embryogenesis suspension.
