Introduction
Rauwolfia serpentina, commonly known as sarpagandha, is a medicinal plant belonging to the Apocynaceae family. Known for its therapeutic properties, particularly the active alkaloid reserpine, which is used for treating hypertension, the plant contains various bioactive components. Traditional propagation methods like cutting or grafting have proven ineffective for this species, necessitating alternative approaches such as micropropagation. The study highlighted in this article aims to enhance the propagation of Rauwolfia serpentina through in vitro techniques, focusing on multiple shoot generation for successful clonal propagation.
Efficient Multiple Shoot Generation
The study investigated the effects of different concentrations of Benzyl Adenine Purine (BAP) and its combination with Indole Butyric Acid (IBA) on multiple shoot generation using stem tips and nodal segment explants. The results indicated that the best results for multiple shoot formation were attained in a static MS medium enriched with 5.0 mg/l BAP and 0.5 mg/l IBA, yielding a remarkable 85.6% shoot multiplication rate. In the subsequent rooting phase, the regenerated shoots were cultured on media with various concentrations of IBA and Indole Acetic Acid (IAA). The optimal rooting success (76.6%) was achieved with 0.5 mg/l IBA, demonstrating that the combination of BAP and IBA significantly contributed to the successful propagation of this medicinal plant.
Conclusion
The study successfully demonstrates that micropropagation via multiple shoot generation is an effective method for propagating Rauwolfia serpentina. By utilizing specific concentrations of BAP and IBA, a high rate of shoot induction and rooting was achieved. Additionally, acclimatization of plantlets to open field conditions led to a 74% survival rate, indicating the feasibility of this method for the cultivation and conservation of Rauwolfia serpentina. This research highlights the importance of tissue culture in enhancing the availability of this valuable medicinal species, helping to meet the growing demand while ensuring its sustainability.
