Achyranthes aspera L. is a highly valuable medicinal plant in Bangladesh, traditionally exploited for its bioactive secondary metabolites. Over harvesting from natural habitats necessitates the development of a reliable, large scale propagation protocol. This study establishes an efficient, highly reproducible in vitro seed germination and direct micropropagation pathway for A. aspera utilizing nodal segments and shoot apices. The maximum in vitro seed germination rate (100%) was achieved on Murashige and Skoog (MS) medium supplemented with 2.0 mg/l 6-benzyl amino purine (BAP) within 6-9 days. For multiple shoot buds (MSBs) induction, shoot apices exhibited superior organogenic potential compared to nodal segments. The highest frequency of MSBs induction (94%) and maximum number of shoots per explant (5.10 ± 0.37) were recorded on MS medium fortified with 2.0 mg/l BAP and 1.0 mg/l Indole-3-acetic acid (IAA) within 11-14 days. Nodal segments also performed optimally under BAP influence, yielding 4.33 ± 0.32 shoots per explant (92% induction) on MS medium with 2.0 mg/l BAP and 1.0 mg/l α-Naphthalene acetic acid (NAA). For shoot elongation, MS medium containing 1.0 mg/l BAP and 0.5 mg/l NAA facilitated the maximum longitudinal growth (4.68 ± 0.32 cm). Vigorous in vitro rhizogenesis (94% rooting frequency, 5.46 ± 0.20 roots per shoot, 3.98 ± 0.17 cm increased length) was achieved on half-strength MS medium supplemented with 1.0 mg/l Indole-3-butyric acid (IBA) after 30d of culture. Successfully rooted seedlings were acclimatized ex vitro with an 80% survival rate, displaying normal morphological development without somaclonal variations. This optimized protocol provides a robust foundation for the commercial cultivation, pharmaceutical exploitation and germplasm conservation of A. aspera.
