Popis: Ammannia baccifera L. is a wetland medicinal herb that belongs to the family Lythraceae. This plant is very notable to have a wide scope in pharmacological, therapeutic and medicinal properties. The current examination imparts an effective, proficient and fast strategy of commercial proliferation to satisfy the folklore medicinal and pharmacological demands of the market. A large-scale micropropagation of Ammannia baccifera L was done through a meticulous and a well-organized procedure. The leaf segments were cultured on MS medium augmented with different concentrations (0.5–2.5 mg/l) of 6- benzylaminopurine (BAP), (0.5- 2.0 mg/l) 1- naphthaleneacetic acid (NAA) and (1.0- 2.0 mg/l) 2,4- Dichlorophenoxyacetic acid (2,4-D) and were used for callus initiation. BAP at 1.0 mg/l combined with 0.5 mg/l NAA was found to be the best concentration and combination for initiation of high frequency of reddish green nodular callus (95.00±1.87) and good response for leaf explants. For shoot regeneration, MS medium blended with BAP at 1.5 mg/l and IAA at 0.6 mg/l produces maximum percentage of shoots from the callus derived by leaf explant. The leaf segments produce maximum percentage shoots (90.00±1.52), total number of shoots per explant (26.33±1.45) and length of shoot (9.63±0.73 cm). However, healthy established shoots were cultured on MS medium fortified with 1.5 mg/l indole-3-butyric acid (IBA) along with 2.0 mg/l. Indole-3-acetic acid (IAA) was found to be best for the root initiation and production in the leaf segments (95±1.57), number of roots (19.33±0.88) and root length (8.63±0.61cm). The regenerated plantlets were relocated to paper cups filled with vermiculite:sand:soil in the proportion of 1:2:1 (w/w) and were then transferred into outdoor conditions.
