Effects of different factors on adventitious bud induction from stem explants of Ludisia discolor
Abstract
In this study, the stem explants of Ludisia discolor were used as experimental materials to investigate the effects of 6-BA, NAA, Cu2+ and Ag+ on the induction of adventitious bud regeneration, and to analyze the most suitable culture conditions for stem explants regeneration. The results showed that when the medium was supplemented with 1.0 mg/L 6-BA, 0.75 mg/L NAA, 0.25 mg/L CuSO4, or 6.4 mg/L AgCl, the best regeneration effects would be gained, respectively. And the adventitious bud regeneration rate reached the maximum, which were 61.67%, 83.67%, 80.95% and 87.63%, respectively. The results of this study provided a theoretical basis for tissue culture and rapid propagation of L. discolor.
