A protocol was established for mass propagation of the valuable medicinal plant Ficus religiosa L. (Moraceae) through in vitro culture using apical and axillary buds of young sprouts from selected plants. Best shoot induction was observed on MS basal medium supplemented with 0.5 mg/l BAP + 0.1 mg/l IAA, in which 78 per cent of the explants produced 16 shoots per culture. Repeated subcultures in the same medium, resulted rapid shoot multiplication with 24 shoots per culture. In vitro raised shoots rooted on half strength MS supplemented with 2.0 mg/l IBA + 0.1 mg/l NAA. For acclimatization and transplantation, the plantlets in the rooting culture tubes were kept in normal room temperature for seven days before transplanting in pots where plantlets were reared for three weeks. The survival rate of regenerated plantlets was 85 per cent.  Key words: Ficus religiosa, Medicinal plant, Shoot proliferation, Regeneration,                   Acclimatization D.O.I. 10.3329/ptcb.v19i1.4987 Plant Tissue Cult. & Biotech. 19(1): 71-78, 2009 (June)

An efficient protocol was established for rapid and large scale propagation of woody aromatic medicinal plant Vitex negundo L. by in vitro shoot multiplication from shoot tips and nodal segments of mature plant. Of the four different growth regulators BA, Kn, GA3, NAA and coconut water, MS fortified with BA 1.0 mg/l was found to be the most effective for inducing multiple shoots from nodal explants. The percentage (96%) of shoot multiplication per node (21.83) was highest up to second subculture passages, after which there was a gradual decline in shoot development. Best rooting was induced (93%) in excised shoots on half strength MS medium supplemented with an optimal combination of NAA (0.3 mg/l). Soil, compost and sand (1:1:1) mixture was the most suitable planting substrate for hardening. The survival rate was 80% and the regenerated plants were successfully transferred to the soil.Key words: Vitex negundo, Medicinal plant, Shoot proliferation, Micropropagation, RegenerationDOI = 10.3329/bjsir.v43i3.1149Bangladesh J.

Shoot multiplication of Bupleurum distichophyllum was achieved from the nodal and shoot tip explants of mature plants using MS with different concentrations and combinations of growth regulators. Maximum explant response was from axillary shoots and the highest number of shoots per explant was obtained on MS fortified with 1.0 mg/l BAP. The highest degree of axillary shoot proliferation was found to be 74 and 70% for nodal- and shoot tip explants, respectively on the medium containing 1.0 mg/l BAP + 0.1 mg/l NAA. The combination of BAP and GA3 was also found to be effective for both type of explants. The degree of shoot formation was affected by explant types and the exogenous hormonal regime in the medium. The regenerated shoots were successfully rooted on MS supplemented with 2.0 mg/l IBA, after sequential hardening, survival rate was 71%.

Abstract Clerodendrum phlomidis L. f. is an important medicinal plant of the Lamiaceae family, particularly its roots, which are used for various therapeutic purposes in a pulverized form. The objective of this study was to develop a standard protocol for axillary shoot proliferation and rooting of C. phlomidis for its propagation and conservation. Nodal explants were inoculated on Murashige and Skoog (MS) medium that was supplemented with one of six cytokinins: 6-benzyladenine, kinetin, thidiazuron, N6-(2-isopentenyl) adenine (2iP), trans-zeatin (Zea) and meta-topolin. Callus induction, which was prolific at all concentrations, formed at the base of nodal explants and hindered shoot multiplication and elongation. To avoid or reduce callus formation with the objective of increasing shoot formation, the same six cytokinins were combined with 4 μM 2,3,5-tri-iodobenzoic acid (TIBA) alone or in combination with 270 μM adenine sulphate (AdS). Nodal explants that were cultured on the medium supplemented with 9.12 μM Zea, 4 μM TIBA and 270 μM AdS produced significantly more and longer shoots than on medium without TIBA and AdS. Half-strength MS medium supplemented with 8.05 μM α-naphthaleneacetic acid was the best medium for root formation. Most (75%) in vitro rooted plantlets were successfully acclimatized under natural conditions.

Plantlets were recovered from axillary bud cultures of muscadine grape (Vitis rotundifolia, `Summit'). Nodal segments 0.5 to 1.0 cm long were cultured in Murashige and Skoog (MS) basal medium supplemented with 5, 10, 20, or 40 μm BA. Best total shoot production was obtained with 10 μm BA; with higher BA levels, shoots were unexpanded and exhibited high mortalities. MS medium supplemented with IBA enhanced rooting by increasing rooting percentage and number per plantlet. Shoots previously proliferated on medium with 5 μm BA rooted significantly better than those multiplied on 10 μM BA. Shoot vigor during rooting was greater in shoots proliferated on 5 vs. 10 μm BA. Root development was not significantly affected by liquid vs. agar-solidifted medium or shoot length. Chemical names used: N-(phenylmethyl) -1H-purin-6-amine (BA), 1H-indole-3-butyric acid (IBA).

Optimal axillary shoot proliferation was obtained from stem explants of a clone of Eriostemon myoporoides DC. on Murashige and Skoog (MS) basal medium containing 0.1 mg BA/liter, and of Eriostemon `Stardust' on MS medium containing 0.5 mg BA/liter. Overall average number of shoots and shoot lengths for all treatments was greater for E. `Stardust' (22.4 shoots and 12.1-mm shoot length) than for E. myoporoides (4.5 shoots and 8.3-mm shoot length). Maximum percent rooting of E. myoporoides (42%) and E. `Stardust' (95%) was obtained on MS medium supplemented with 1.0 mg K-IBA/liter for E. myoporoides and 0.1 mg NAA/liter for E. `Stardust'. Overall average percent rooting and root lengths were greater for E. `Stardust' (42% rooting and 11.0-mm root length) than for E. myoporoides (27% rooting and 2.3-mm root length). For E. `Stardust', reducing sucrose in the rooting medium from 50 to 25 g·liter-1 significantly decreased overall average percent rooting to 1670 and root length to 6.8 mm. Plantlets of both clones were acclimatized in the greenhouse and transferred successfully to soil, although survival was <7070. Chemical names used: N -(phenylmethyl) -l H -purine-6-amine (BA); potassium-l H -indole-3-butyric acid (K-IBA); l-naphthaleneacetic acid (NAA).

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.

Several rose species (Rosa rugosa, R. wichuraiana, R. setigera, R. laevigata, R. banksiae, R. roxburghii, R. odorata and hybrids) were employed to establish the appropriate nutrient media for shoot multiplication and root initiation of cultured shoots and to describe a procedure for the successful transfer to soil of plants obtained in vitro. Cultured shoot tips and lateral buds from different genotypes proliferated multiple shoots on a basal medium (MS salt, vitamins, glycine, sucrose and agar) supplemented with 0mg/l to 6mg/l 6-benzylamino purine (BA) and 0mg/l to 0.5 mg/l naphthalene acetic acid (NAA). Most rose species cultured in a modified MS medium supplemented with 2mg/l BA showed good growth and shoot proliferation. The buds nearest the apex exhibited the slowest rate of bud development. Root development was enhanced and shoot development inhibited by lowering the concentration of MS salts to quarter- and half-strength. With difficult-to-root species, rooting was improved by supplementing the media with auxin or giving them 3-7days of dark treatment.

Hybrids between Corymbia torelliana (F.Muell.) K.D.Hill & L.A.S.Johnson and C. citriodora subsp. variegata (F.Muell.) A.R.Bean & M.W.McDonald are used extensively to establish forestry plantations in subtropical Australia. Methods were developed for in vitro seed germination, shoot multiplication and plantlet formation that could be used to establish in vitro and ex vitro clone banks of juvenile Corymbia hybrids. Effects of sodium hypochlorite concentration and exposure time on seed contamination and germination, and effects of cytokinin and auxin concentrations on shoot multiplication and subsequent rooting, were assessed. A two-step surface sterilisation procedure, involving 70% ethanol followed by 1% sodium hypochlorite, provided almost no contamination and at least 88% germination. A novel method of cytokinin-free node culture proved most effective for in vitro propagation. Lateral bud break of primary shoots was difficult to induce by using cytokinin, but primary shoots rooted prolifically, elongated rapidly and produced multiple nodes in the absence of exogenous cytokinin. Further multiplication was obtained either by elongating lateral shoots of nodal explants in cytokinin-free medium or by inducing organogenic callus and axillary shoot proliferation with 2.2 µm benzyladenine. Plantlets were produced using an in vitro soil-less method that provided extensive rooting in sterile propagation mixture. These methods provide a means for simultaneous laboratory storage and field-testing of clones before selection and multiplication of desired genotypes.
