Abstract:
Objective Callus induction and plantlets regeneration of Pogostemon cablin(Blanco)Benth.are studied to establish a high-efficiency regeneration system for tissue culture.Methods The leaf segments,nodular stem segments,stem segments and root tips from Pogostemon cablin(Blanco)Benth.were cultured in vitro.The factors which affect the induction,multiplication and differentiation of callus were studied.Results Benzylaminopurine(BA) or thidiazuron(TDZ) combined with ?-naphthylacetic acid(NAA) was helpful to induce callus.The optimal concentrations of BA were 0.2～0.5mg/L.Nodular stem segments and stem segments were the most suitable explants for callus induction.The medium containing BA and NAA promoted the multiplication of callus.The multiplication rate and differentiation rate of 30-day callus were much higher than those of 60-day callus.BA was helpful to induce callus differentiation.The callus from leaf segments exerted a higher differentiation rate.Conclusion A high-efficiency regeneration system of callus induction and plant regeneration from Pogostemon cablin(Blanco)Benth.has been established.
