AbstractMerremia quinquefolia, is an important medicinal plant of the family Convolvulaceae known for its vasoconstrictor, uterotonic, neurohormonic, sympathicolytic and sedative effects. In the present investigation effect of cytokinins 6-benzylaminopurine (BAP), kinetin (Kn) and thidiazuron (TDZ), at concentrations 1.0, 2.0, 3.0, 4.0 and 5.0 mg·dm−3 on in vitro shoot multiplication from nodal explants of M. quinquefolia was evaluated. Bud breaking and emergence of shoots started within 10-15 days of inoculation in all media containing cytokinin. Murashige and Skoog (MS) medium supplemented with 4.0 mg·dm−3 BAP resulted in maximum number of shoots from single node within 45 days. In vitro raised shoots were successfully rooted on ½ mineral salts of MS medium with 3% sucrose supplemented with 2.0 mg·dm−3 indole-3-butyric acid (IBA). This is the first report on in vitro propagation of Merremia quinquefolia. This study can be useful for development of micropropagation protocols for related taxa.

Clerodendrum Phlomidis

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.

Shoot explants from actively growing, greenhouse-maintained plants of Baptisia `Purple Smoke' were cultured in vitro for shoot initiation on Murashige and Skoog (MS) basal medium containing vitamins and supplemented with 30 g·L–1 sucrose, 8.87 μm BA, and 4.14 μm K-IBA. All subsequent media were supplemented with 2.47 mm NaH2PO4 to enhance shoot growth. Single-node explants were subcultured for shoot multiplication on MS medium with either no plant growth regulator or with 2.22, 4.44, 8.87, 17.74, or 35.48 mm BA in combination with 0.0 or 4.14 μm K-IBA. Explants produced a maximum of 4.1 shoots on the medium with 2.22 μm BA. Shoots rooted on all concentrations of K-IBA (2.07, 4.14, 10.36, or 20.72 μm) and K-NAA (2.23, 4.46, 11.15, or 22.29 μm) tested. Maximum rooting was 100% on MS medium with 11.15 μm K-NAA; however, this treatment induced copious stem callusing. Rooted shoots were greenhouse-acclimatized for 2.5 weeks. Overall survival was 86%. For optimal rooting and subsequent acclimatization, treatment with 2.23 μm K-NAA is recommended; this resulted in 83% rooting and 87% acclimatization. Chemical names used: N6 benzyladenine (BA); potassium salt of indole-3-butyric acid (K-IBA); potassium salt of 1-naphthalene acetic acid (K-NAA).

A tissue culture protocol was developed for an important medicinal plantRungia pectinataL. in the present study. Nodal shoots were used as explants and surface-sterilized with 0.1% HgCl2solution. Murashige and Skoog (MS) medium was used to establish the cultures ofR. pectinata. The bud break was reported on MS medium supplemented with 1.0 mg L−16-benzylaminopurine (BAP). About 98% response was observed with this media combination and maximum 3.2 shoots per explant with 4.3 cm length were recorded. The shoots were further multiplied using MS medium augmented with 0.5 mg L−1each of BAP and kinetin (Kin) + 0.1 mg L−1indole-3 acetic acid (IAA). Maximum 13.2 shoots per explant with 5.2 cm length were observed. All the shoots were rooted (4.9 roots per shoot with 3.5 cm length) on half strength MS medium fortified with 2.0 mg L−1indole-3 butyric acid (IBA).In vitroflowering was induced from the shoots on half strength MS medium supplemented with same concentrations and combinations of growth regulators used for shoot multiplication under 12/12 hr light/dark photoperiod. The plantlets were hardened in the greenhouse for two months and finally transferred to the field. The foliar micromorphological studies revealed the developmental changes in stomata, vein density, and trichomes during the culture of shoots underin vitroconditions.

The present paper reports the phytochemical and micropropagation investigations of an undermined plant, Gymnema sylvestre. Gymnema sylvestre which has a place with the family Asclepiadaceae is a lasting moderate developing restorative woody climber generally called as “Gudmar“. There is a developing interest for leaves of G. sylvestre in the pharmaceutical exchange because of its utilization as a solution for diabetes and furthermore as a tonic of the nerves and as a diuretic. Proliferation of this plant is regularly hard and costly. In the present review the subjective examination affirmed the nearness of different phytochemicals like alkaloids, flavonoids, phenols, tannins, terpenoids and glycosides. Quantitative estimation of flavonoids and phenols was likewise completed and antimycotic potential further evaluated using standardized assays. In vitro proliferation is an option technique for spread of the undermined and imperiled plant which can help its preservation. The nodal explants were refined on MS medium containing diverse focus and mixes of development controllers like 6-benzylaminopurine (BAP) and indoleacetic corrosive (IAA). Different shoot buds were regener-ated effectively from the nodal explants which were proficiently established on 1⁄2 quality MS medium supplemented with IBA. The recovered plantlets were effectively exchanged to the glasshouse, acclimatized and exchanged to the field.

Bud Breaking

High demand for edible bamboo shoots ofBambusa tuldaandMelocanna bacciferain many Asian ethnic groups has led to the need for developing intensive bamboo farming. To achieve this,in vitroregeneration of bamboo plantlets is needed due to the long and irregular bamboo flowering cycle and scarcity of bamboo seeds. An effective protocol for plantlets regeneration inB. tuldaandM. bacciferafrom nodal explants following validation of the species using the sequence of trnL-F intergenic spacer region is described. Effective axillary bud breaking was achieved at 3 mg/L of 6-benzylaminopurine (BAP) in MS medium. Importantly, combining 2 mg/L of kinetin (Kn) with 3 mg/L of BAP produced a synergistic effect for shoot multiplication inB. tuldaandM. baccifera. Under optimized conditions in half-strength MS medium supplemented with 3 mg/L of indole-3-butyric acid (IBA), 10 mg/L of coumarin, and 3% sucrose, profuse production of dark-brown rhizome inB. tuldaand abundant rooting (81.67%,P<0.05,F=15.46) forM. bacciferawithin 30 days were achieved. The established protocol and the validation of the reported species at the molecular level will be of help to stakeholders in edible bamboo trade to conserve gene-pool and increase productivity.

This study aims to investigate whether the in vitro-cultured L. pumila var. alata has higher antioxidant activity than its wild plant. An 8-week-old L. pumila var. alata nodal segment and leaf explants were cultured onto Murashige and Skoog (MS) medium supplemented with various cytokinins (zeatin, kinetin, and 6-benzylaminopurine (BAP)) for shoot multiplication and auxins (2,4-dichlorophenoxyacetic acid (2,4-D) and picloram) for callus induction, respectively. The results showed that 2 mg/L zeatin produced the optimal results for shoot and leaf development, and 0.5 mg/L 2,4-D produced the highest callus induction results (60%). After this, 0.5 mg/L 2,4-D was combined with 0.25 mg/L cytokinins and supplemented to the MS medium. The optimal results for callus induction (100%) with yellowish to greenish and compact texture were obtained using 0.5 mg/L 2,4-D combined with 0.25 mg/L zeatin. Leaves obtained from in vitro plantlets and wild plants as well as callus were extracted and analyzed for their antioxidant activities (DPPH and FRAP methods) and polyphenolic properties (total flavonoid and total phenolic content). When compared with leaf extracts of in vitro plantlets and wild plants of L. pumila var. alata, the callus extract displayed significantly higher antioxidant activities and total phenolic and flavonoid content. Hence, callus culture potentially can be adapted for antioxidant and polyphenolic production to satisfy pharmaceutical and nutraceutical needs while conserving wild L. pumila var. alata.
