Plant Growth Regulators Promotes Organogenesis in the Diploid and Tetrploid Codonopsis lanceolata

Codonopsis lanceolata is a perennial creeper that is used for food or medicine. Recently, functional substances of medicinal plants have been attained increasing attention, but research on breeding and cultivation method to increase yields is still limited. Therefore, the purpose of this study was to examine the effects of plant growth regulators (PGR) on organogenesis in diploid and tetraploid C. lanceolata with the purpose of acquiring mass propagation of superior species of C. lanceolata.
