From: Micropropagation of Andrographis producta through axillary and adventitious shoot regeneration
Histological studies on shoot regeneration from varied explants of Andrographis producta. A Longitudinal section of the nodal explant developed on MS medium with 10 μM 2-iP after 2 weeks of culture showing direct shoot regeneration (bar-, 0.075 cm). B Section through 4-week-old shoot tip cultured on MS medium containing 5 μM BAP showing multiple shoot regeneration (bar-, 0.112 cm). C Transverse section of 4-weeks-old shoot tip explant cultured on 10 μM 2-iP showing direct shoot induction (bar-, 0.075 cm) (Black- colored arrows indicate newly formed shoot buds and shoot, and red arrows indicate original explants)
