An efficient protocol was developed for in vitro mass propagation of an important medicinal shrub, Plumbago zeylanica L., (Plumbaginaceae) through direct organogenesis using shoot tip and nodal explants. Best shoot induction was observed on MS basal medium supplemented with 0.5 mg/l BAP, in which 86.4% of nodal explants responded to produce maximum number (12.4 ± 0.66) of shoots per culture. In vitro raised shoots rooted on half strength MS medium with 0.5 mg/l IAA. For acclimatization and transplantation, the plantlets in the rooted culture tubes were kept in normal room temperature for 7 days before transplanting in pots where plantlets were reared for three weeks. The survival rate of regenerated plantlets was 85%. DOI: http://dx.doi.org/10.3329/bjsir.v47i3.13063 Bangladesh J. Sci. Ind. Res. 47(3), 297-302 2012

An efficient protocol was developed for shoot proliferation and plant regeneration of Phlogacanthus thyrsiflorus Nees. (Acanthaceae) - a rare medicinal shrub of Bangladesh, through in vitro culture using shoot tip and nodal explants. Best shoot induction was observed on MS with 1.0 mg/l BAP + 0.5 mg/l NAA, in which 84.2% of nodal explants responded to produce maximum number (12.4 ± 0.66) of shoots per culture. In vitro raised shoots rooted on half-strength MS with 0.5 mg/l IBA + 0.5 mg/l NAA. For acclimation and transplantation, the plantlets in the rooting culture tubes were kept in normal room temperature for 7 days before transplanting in pots where plantlets were reared for three weeks. The survival rate of regenerated plantlets was 85%. Key words: Phlogacanthus thyrsiflorus, Shoot proliferation, Plant regeneration   D. O.

A protocol was established for mass propagation of a valuable medicinal herb, Eclipta alba (Linn.) Hassk (Asteraceae) through in vitro culture. Apical and axillary buds of young sprouts from selected plants were used as explants. Best shoot induction was observed on MS basal medium supplemented with 0.5 mgl-1 BAP + 0.1 mgl-1 NAA, in which 94% of the explants produced 18 shoots per culture. Repeated subcultures in the same medium, resulted rapid shoot multiplication with 26 shoots per culture. In vitro raised shoots rooted on half strength MS medium with 1.0 mgl-1 IBA +1.0 mgl-1 NAA. For acclimatization and transplantation, the plantlets in the rooting culture tubes were kept in normal room temperature for 7 days before transplanting in pots where plantlets were reared for three weeks. The survival rate of regenerated plantlets was 80%. Key words: Eclipta alba, Medicinal plant, Shoot proliferation, Micropropagation, Acclimatization   DOI: 10.3329/bjsir.v43i2.965 Bangladesh J. Sci.

A consequency was obtained for mass propagation of a valuable ayurvedic medicinal herb, Heliotropium indicum Linn. (Boraginaceae) through in vitro culture. Apical and axillary buds of young sprouts from selected plants were used as explants. Best shoot induction was observed on MS basal medium supplemented with 0.5 mg/l BAP + 0.1 mg/l GA3, in which 92% of the axillary buds explants produced 12 shoots per culture. Repeated subcultures in the same medium, resulted rapid shoot multiplication with 18 shoots per culture. In vitro raised shoots rooted on half strength MS medium with 0.5 mg/l IBA. For acclimatization and transplantation, the plantlets in the rooting culture tubes were kept in normal room temperature for 7 days before transplanting in pots where plantlets were reared for three weeks.

An efficient protocol was established for in vitro mass propagation of a valuable medicinal shrubby plant, Mimosa pudica Linn., from shoot tip and nodal explants. Optimum in vitro shoot induction was observed from nodal explants on MS basal medium supplemented with 1.5 mg/l BAP + 0.5 mg/l NAA, in which 88.2% of the explants produced 9 shoots per culture within 3-4 weeks. Repeated subcultures in the same medium, resulted rapid shoot multiplication with 20.4 ± 1.20 shoots per culture within 12 weeks. The healthy in vitro raised shoots rooted on half strength MS medium with 0.5 mg/l IBA. For acclimatization and transplantation, the plantlets in the rooting culture tubes were kept in normal room temperature for 7 days before transplanting in pots where plantlets were reared for three weeks. The survival rate of regenerated plantlets was 80%.

An efficient in vitro mass propagation and promising protocol has been successfully standardized and developed for Coleus forskohlii through direct organogenesis from nodal explants. Nodal explants cultured onto MS basal medium supplemented with 4.44 μM BAP recorded the highest response and produced 24.3 ± 0.2 shoots per explant with an average shoot length 5.6 ± 0.4 cm after 30 days of culture. The in vitro shoots recorded higher response for development of rooting on half strength MS fortified with 2.46 μM IBA which produced the best response 7.8 ± 0.6 roots per in vitro shoot with an average root length of 4.3 ± 0.1 cm after 25 days. The in vitro rooted plantlets were transferred for hardening and 90% of the plantlets survived were successfully acclimatized and established in small plastic pots. This protocol recorded to be a highly repeatable, successful and rapid technique that could be utilized for the commercial mass propagation and ex situ conservation of Coleus forskohlii. It is important to note that the morphology of the in vitro plantlets of Coleus forskohlii showed a true-to-type growth habit, both in vitro and when transferred to ex vitro growth conditions.

Best shoot induction was observed on MS medium supplemented with 0.5 mg/l       BAP, in which 92% of nodal explants responded to produce maximum number (42.8 ± 1.18) of shoots per explants. In vitro raised shoots       rooted on half strength of MS medium with 0.5 mg/l IAA. For acclimatization and transplantation, the plantlets in the rooting culture tubes were kept in normal room temperature for 7 days before transplanting them in pots containing soil where plantlets were reared for three weeks. The survival rate of regenerated plantlets was 82%.   DOI: http://dx.doi.org/10.3329/bjsir.v47i2.11452   Bangladesh J. Sci. Ind. Res. 47(2), 197-202, 2012
