Baikal skullcap (Scutellaria baicalensisGeorgi.),a member of the Lamiaceae familyhas been commonly used in traditionalmedicine. Baikal skullcap (called“Hoang cam” in Vietnamese) was introduced into Vietnam and has been planted in some areasin this country. Due to its naturally slow growth and development, large growing areas have not been developed yet. Presently, the most common method of propagation of Baikal skullcap isusingits seeds. Thisstudywas conducted toestablish a rapid micropropagation protocol that can beappliedfor multiplicationof elite strainsand actively provide the disease-free seedlings. The seeds were sterilized using0.5% Presept solution for 15 min, then placed on a medium containing water, sucrose, and agar for germination. Microshoots were highly induced and multiplied (7.47 ± 0.57 shoots/explant) on MS medium supplemented with 1mg/l BA. The suitable sucrose concentrations for the growth and development of microshoots were 20 g/l or 30 g/l. Allshoots were rootedby 100% by addingMS medium supplemented with 0.8-1.6 mg/l IBA. Therefore, theestablished protocol can be applied forin vitro micropropagationofBaikal skullcap.
