Summary of philosophy doctoral dissertation on biology: Regeneration and micropropagation of Ngoc Linh ginseng (Panax vietnamensis Ha et Grushv.) using thin cell layer technique

The objective of the study was to find the explant resources, the type and concentration of plant growth regulators (PGRs), as well as the in vitro culture conditions suitable for different morphogenesis processes - callus induction, direct embryogenesis, shoot and root formation, etc. The growth and development of in vitro Ngoc Linh ginseng derived from thin cell layer (TCL) was examined in Quang Nam to assess the adaptability of in vitro Ngoc Linh plantlets in its natural territory, compared to those growing in Bidoup - Nui Ba National Park, Lam Dong.
