dc.descriptionDescription: The present investigation was conducted at Plant Tissue Culture Laboratory, Biotechnology Centre, Dr.P.D.K.V., Akola (MH). Sarpagandha (Apocynaceae) is a woody perennial medicinal shrub, and the plant is rare, endangered plant. Present investigation showed micropropagation protocol for mass in-vitro propagation of the plant to fulfill the demand of pharmaceuticals and industries at commercial and economic level.en_US
dc.description.abstractAbstract: The nodal segment and shoot tips were excised from a field grown plants for the investigation and inoculated on Murashige and Skoog medium supplemented with BAP. Nodal segment proved best as explant for in-vitro shoot proliferation than shoot tips. Therefore, nodal segment was used as an explant in present investigation. Among all the treatments bavistin 0.1% for 30 min, streptomycin 1.0% for 15 min, sodium hypochlorite 1.0% for 10 min and mercuric chloride 0.1% for 10 min duration was recorded as the best for surface sterilization and gave higher survival of explants. MS media supplemented with BAP with various concentrations in which MS+ 5 mg/l showed early response in ±6.93 days, number of shoots found was 4.13, regeneration 76.33% and height 5.53 cm. MS media supplemented with combination of BAP and IBA proved more responsive and effective for proliferation than BAP alone. MS+ 5 mg/l BAP + 0.5 mg/l IBA was found significantly better with 5.52 number of shoots and 81.30% shoot proliferation. Explants were found slightly more responsive in media combination MS + 5 mg/l BAP + 1.0 mg/l IBA with ±6.53 days and maximum height of shoots with 6.93 cm. For in-vitro shoot multiplication 3% sucrose concentration in MS media was proved best. Root induction in the regenerated shoots was found best in ½ MS media supplemented with 2.5 mg/l NAA + 2.0 mg/l IAA + 0.7% agar + 3% sucrose+ 0.65 g/l charcoal it responded in ±29.3 days and showed the highest root length with 2.9 cm among any other treatments. 1:3 soilrite and cocopeat hardening media with watering after 1 day proved best for primary hardening of the plantlets with maximum survival. The results obtained from the present investigation indicate that, in-vitro regeneration protocol will provide technique that can be successfully used for mass in-vitro propagation of sarpagandha species, Rauwolfia serpentina L.en_US
