- Abstract
Andrographis paniculata (Burm. f.) Wall. ex Nees is an economically high‐demand medicinal plant for its traditional uses and overwhelming pharmacological properties. However, the current agricultural production of A. paniculata is insufficient to meet its pharmacological demand. Developing a rapid and efficient propagation technique is crucial to meet its increasing demand. This study assessed the ability of the auxins indole‐3‐butyric acid (IBA) and indole‐3‐acetic acid (IAA) to simulate adventitious root development in the young apical shoot (YAS) and old apical shoot (OAS) cuttings of A. paniculata. This investigation found that 3.0 mM IBA was better for achieving rapid growth (6.33 ± 0.42 d) of adventitious root in YAS cuttings, where the number of roots per cutting was 40 ± 1.29, with an average length of 4.11 ± 0.20 cm (mean ± SE; n = 6). Overall, YAS cuttings were comparatively more efficient to induce adventitious roots compared with OAS cuttings. The rapid regeneration of A. paniculata plantlets using IBA within a short time suggests that this plant can be propagated on a mass scale and that IBA can be used to accelerate production. Further study for evaluating soaking duration on the adventitious rooting in A. paniculata would be worthy. Core Ideas: External auxin significantly increased the root development in A. paniculata.Indole‐3‐butyric acid (IBA) was comparatively more effective than indole‐3‐acetic acid (IAA).IBA induced roots rapidly in young shoots (6.33 d) than old shoots (8.33 d).Shoot cutting soaking into auxin might be a suitable technique for commercial production.
