An efficient plant regeneration protocol was developed for Artemisia annua, an aromatic medicinal herb. Nodal explants inoculated on MS supplemented with 4.44 ?M BAP showed better growth response and produced 116.2 ± 0.1 micro-shoots of an average length 1.9 ± 0.3 cm after 35 days culture. The cluster of small shootlets were cultured on shoot elongation medium supplemented with 1.44 ?M GA3 and 10% coconut milk (CM) showed shoot elongation up to 4.6 ± 0.7 cm. Roots were induced after transfer to half strength MS supplemented with 2.46 ?M IBA produced 14.3 ± 0.2 roots with an average height of 4.3 ± 0.53 cm after 30 days. The rooted plantlets were transferred for hardening, 80 per cent of plantlets survived and resumed growth in the mixture of soil, vermiculite and farm yard manure (1 :  1 : 1).

A protocol for multiple shoot induction and plant regeneration from nodal explants of Ocimum citriodorum has been developed. Nodal explants inoculated on Murashige and Skoog (MS) medium supplemented with 1.0 mg/l Benzyl adenine (BAP) and 0.025 mg/l indole -3- acetic acid (IAA) showed better growth response (80%) and produced 15.2 ± 1.28 shoots per explant with an average length of 6.17 ± 0.29 cm after 35 days. Roots were induced after transfer to half strength MS medium supplemented with 0.5 mg/l Indole -3- butyric acid (IBA) produced 6.0 ± 1.0 roots with an average height of 4.9 ± 0.26 cm after 30 days. Plantlets with well developed root and shoot systems were successfully acclimated (80 %) and established in earthen pots containing mixture of soil, vermiculite and farm yard manure (1:1:1).

In Vitro Shoot Proliferation

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.

Basal Media

Shoots were induced from axillary and nodal buds of Magnolia punduna on MS supplemented with 0.1 μm of BAP. Out of five basal media tested (MS, ½ MS, ¼ MS, LS and WP), MS was found to be most effective for shoot and callus initiation. Different plant growth regulators (0.1 ‐ 1.0 μm) induced shoot formation in different proportions. The combination of 0.1 μm IBA and 0.5 μm BAP was found optimum for shoot elongation with minimal necrosis of the explants. Half strength of MS supplemented with 8.0 μm IBA was found suitable for rooting.Plant Tissue Cult. & Biotech. 27(2): 153-159, 2017 (December)

Bauhinia Forficata

Plant regeneration was achieved from cells of callus induced from hypocotyl segments of Bauhinia forficata on half strength Murashige and Skoog culture medium supplemented with several concentrations of BAP. Within 40 days of culture shoot buds formation was observed on callus surface. Calli were then transferred to a same composition culture medium without plant growth regulator in order to induce shoot elongation. Histological studies indicated that in vitro plant regeneration in B. forficata occurred through indirect organogenesis. Meristemoids consisting of small cells with dense cytoplasm and prominent nuclei were randomly distributed throughout the callus surface indicating early stages of shoot bud differentiation. Shoots developed de novo from superficial layers of cells and the pattern of shoot origin and development were very similar to those previously described for other leguminous species.

An efficient system was developed for shoot proliferation and large scale plant regeneration of a seasonal multipotent medicinal herb, Phyllanthus fraternus Webster through in vitro culture. Shoot tips and nodal explants 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 88% of nodal explants responded to produce maximum number (16.8 ± 0.95) of 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. The survival rate of regenerated plantlets was 82%.
