Abstract

Aconitum violaceum Jacq. ex Stapf is a threatened medicinal plant with restricted global distribution. The highest frequency of seed germination was recorded on Murashige and Skoog’s (MS) basal medium, supplemented with 0.5 mg L−1 kinetin with a germination rate of 77.32% and mean germination time of 27 days. Among the various plant growth regulators examined, 0.1 mg L−1 kinetin (Kn) + 0.5 mg L−1 indole-3-acetic acid (IAA) proved to be effective for maximum embryogenic callus production (51.0%) within 31 days of inoculation. The conversion rate of somatic embryos into complete plantlets was highest in the MS medium augmented with 0.1 mg L−1 Kn + 0.5 mg L−1 IAA (68.00%), with an average root initiation time of 25 days. The rooted plantlets were subsequently hardened into jiffy pots with a combination of loamy soil, coco-peat, and vermicompost (1:1:1 v/v), and then transplanted into a greenhouse with a 60% survival rate. To our knowledge, this is the first study on direct in vitro propagation and embryogenic callus induction from seeds. The established regeneration protocol could be employed to propagate A. violaceum on a large scale in a short time. This would contribute significantly to its rapid propagation and germplasm conservation, and establish a framework for the domestication of this highly valued threatened medicinal plant.
