In most of the cases, the regeneration potential of root explants was much higher than that of leaf ones and similar to that of petiole explants, and a combination of 0.3 mg/L benzyladeine with 0.01 mg/L naphthaleneacetic acid was the most effective combination and concentrations for inducing adventitious bud regeneration. Although the best result of bud regeneration was obtained from culture of petiole explants, a good result in regeneration rate of 100% and a high number of 1.75 buds per explant were obtained from culture of root explants. Buds regenerated from root explants initiated roots and became intact plants readily upon transfer to a medium containing 0.01 mg/L naphthaleneacetic acid. Results of the experiments indicated that root was an ideal explant source for rapid propagation by means of tissue culture in this plant species.Read More
